Summary

Determines the shortest paths to visit the input stops and returns the driving directions, information about the visited stops, and the route paths, including travel time and distance.

The service can find routes that visit several input stops in a sequence you predetermine or in a sequence that minimizes overall travel. You can group the input stops into different routes using the RouteName field, and the service will output one route for each group of stops, allowing you to generate routes for many vehicles in a single solve operation.

Legacy:
This is a deprecated tool. See the support article to learn more about how to carry out Network Analysis workflows from the Network Analysis gallery.

Usage

  • Tools in the Ready To Use toolbox areArcGIS Online geoprocessing services that use hosted data and analysis capabilities from ArcGIS Online.

  • The service finds the shortest routes based on travel time if the value for the Measurement Units parameter is time based and on travel distance if the value is distance based.

  • You must specify at least two stops to successfully run the service. You can load up to 10,000 stops and assign a maximum of 150 stops per route.

  • You can include up to 250 point barriers. You can add any number of line or polygon barriers, but line barriers cannot intersect more than 500 street features, and polygon barriers cannot intersect more than 2,000 features.

  • You can use the road hierarchy when solving so that results are generated quicker than exact routes, but the solution may be less than optimal.

  • Regardless of whether the Use Hierarchy parameter is checked (True), hierarchy is always used when the straight-line distance between any pair of stops is greater than 50 miles (80.46 kilometers).

  • The straight-line distance between any pair of stops cannot be greater than 27 miles (43.45 kilometers) when Travel Mode is set to Walking or when it is set to Custom and the Walking restriction is used.

  • If the distance between an input point and its nearest traversable street is greater than 12.42 miles (20 kilometers), the point is excluded from the analysis.

Parameters

DialogPython

LabelExplanationData Type
Stops

Specifies the locations the output route or routes will visit.

You can add up to 10,000 stops and assign up to 150 stops to a single route. (Assign stops to routes using the RouteName attribute.)

When specifying the stops, you can set properties for each—such as its name or service time— using the following attributes:

Name

The name of the stop. The name is used in the driving directions. If no name is provided, a unique name prefixed with Location is automatically generated in the output stops, routes, and directions.

RouteName

The name of the route to which the stop belongs. Stops with the same RouteName value are grouped together.

You can group up to 150 stops into one route.

Sequence

The output routes will visit the stops in the order you specify with this attribute. In a group of stops that have the same RouteName value, the sequence number should be greater than 0 but not greater than the total number of stops. Also, the sequence number should not be duplicated.

If Reorder Stops To Find Optimal Routes is checked (True), all but possibly the first and last sequence values for each route name are ignored so the tool can find the sequence that minimizes overall travel for each route. (The settings for Preserve Ordering of Stops and Return to Start determine whether the first or last sequence values for each route are ignored.)

AdditionalTime

The amount of time spent at the stop, which is added to the total time of the route. The default value is 0.

The units for this attribute value are specified by the Measurement Units parameter. The attribute value is included in the analysis only when the measurement units are time based.

You can account for the extra time it takes at the stop to complete a task, such as to repair an appliance, deliver a package, or inspect the premises.

AdditionalDistance

The extra distance traveled at the stops, which is added to the total distance of the route. The default value is 0.

The units for this attribute value are specified by the Measurement Units parameter. The attribute value is included in the analysis only when the measurement units are distance based.

Generally, the location of a stop, such as a home, isn't exactly on the street; it is set back somewhat from the road. This attribute value can be used to model the distance between the actual stop location and its location on the street if it is important to include that distance in the total travel distance.

AdditionalCost

The extra cost spent at the stop, which is added to the total cost of the route. The default value is 0.

This attribute value should be used when the travel mode for the analysis uses an impedance attribute that is neither time based nor distance based. The units for the attribute values are interpreted to be in unknown units.

TimeWindowStart

The earliest time the stop can be visited. By specifying a start and end time for a stop's time window, you are defining when a route will visit the stop. When the travel mode for the analysis uses an impedance attribute that is time based, specifying time-window values will cause the analysis to find a solution that minimizes overall travel and reaches the stop within the prescribed time window.

Ensure that you specify the value as a date and time value, such as 8/12/2015 12:15 PM.

When solving a problem that spans multiple time zones, time-window values refer to the time zone in which the stop is located.

This field can contain a null value; a null value indicates that a route can arrive at any time before the time indicated in the TimeWindowEnd attribute. If a null value is also present in TimeWindowEnd, a route can visit the stop at any time.

TimeWindowEnd

The latest time the stop can be visited. By specifying a start and end time for a stop's time window, you are defining when a route will visit the stop. When the travel mode for the analysis uses an impedance attribute that is time based, specifying time-window values will cause the analysis to find a solution that minimizes overall travel and reaches the stop within the prescribed time window.

Ensure that you specify the value as a date and time value, such as 8/12/2015 12:15 PM.

When solving a problem that spans multiple time zones, time-window values refer to the time zone in which the stop is located.

This field can contain a null value; a null value indicates that a route can arrive at any time after the time indicated in the TimeWindowStart attribute. If a null value is also present in TimeWindowStart, a route can visit the stop at any time.

CurbApproach

Specifies the direction a vehicle can arrive at and depart from the stop. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Either side of vehicle)—The vehicle can approach and depart the stop in either direction, so a U-turn is allowed at the stop. This setting can be used if it is possible and practical for a vehicle to turn around at the stop. This decision may depend on the width of the road and the amount of traffic or whether the stop has a parking lot where vehicles can enter and turn around.
  • 1 (Right side of vehicle)—When the vehicle approaches and departs the stop, the curb must be on the right side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the right-hand side.
  • 2 (Left side of vehicle)—When the vehicle approaches and departs the stop, the curb must be on the left side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the left-hand side.
  • 3 (No U-Turn)—When the vehicle approaches the stop, the curb can be on either side of the vehicle; however, the vehicle must depart without turning around.

The CurbApproach attribute works with both national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider a stop on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach a stop from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, to arrive at a stop and not have a lane of traffic between the vehicle and the stop, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

LocationType

Specifies the stop type. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Stop)—A location that the route will visit. This is the default.
  • 1 (Waypoint)—A location that the route will travel through without making a stop. Waypoints can be used to force the route to take a specific path (to go through the waypoint) without being considered an actual stop. Waypoints do not appear in directions.

Bearing

The direction in which a point is moving. The units are degrees and are measured clockwise from true north. This field is used in conjunction with the BearingTol field.

Bearing data is usually sent automatically from a mobile device equipped with a GPS receiver. Try to include bearing data if you are loading an input location that is moving, such as a pedestrian or a vehicle.

Using this field tends to prevent adding locations to the wrong edges, which can occur when a vehicle is near an intersection or an overpass, for example. Bearing also helps the tool determine on which side of the street the point is.

BearingTol

The bearing tolerance value creates a range of acceptable bearing values when locating moving points on an edge using the Bearing field. If the Bearing field value is within the range of acceptable values that are generated from the bearing tolerance on an edge, the point can be added as a network location there; otherwise, the closest point on the next-nearest edge is evaluated.

The units are in degrees, and the default value is 30. Values must be greater than 0 and less than 180. A value of 30 means that when Network Analyst attempts to add a network location on an edge, a range of acceptable bearing values is generated 15 degrees to either side of the edge (left and right) and in both digitized directions of the edge.

NavLatency

This field is only used in the solve process if the Bearing and BearingTol fields also have values; however, entering a NavLatency field value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much cost is expected to elapse from the moment GPS information is sent from a moving vehicle to a server and the moment the processed route is received by the vehicle's navigation device.

The units of NavLatency are the same as the units of the impedance attribute.

Feature Set
Measurement Units

Specifies the units that will be used to measure and report the total travel time or travel distance for the output routes.

This parameter value determines whether distance or time will be measured to find the best routes. To minimize travel time for the travel mode (driving or walking time, for instance), specify a time unit. To minimize travel distance for the travel mode, specify a distance unit. This value also determines the units that will be used for total time or distance in the results.

  • Meters—The linear unit will be meters.
  • Kilometers—The linear unit will be kilometers.
  • Feet—The linear unit will be feet.
  • Yards—The linear unit will be yards.
  • Miles—The linear unit will be miles.
  • Nautical Miles—The linear unit will be nautical miles.
  • Seconds—The time unit will be seconds.
  • Minutes—The time unit will be minutes.
  • Hours—The time unit will be hours.
  • Days—The time unit will be days.
String
Analysis Region
(Optional)

The region in which the analysis will be performed. If a value is not specified for this parameter, the tool will automatically calculate the region name based on the location of the input points. Setting the name of the region is required only if the automatic detection of the region name is not accurate for the inputs.

To specify a region, use one of the following values:

  • Europe—The analysis region will be Europe.
  • Japan—The analysis region will be Japan.
  • Korea—The analysis region will be Korea.
  • Middle East And Africa—The analysis region will be Middle East and Africa.
  • North America—The analysis region will be North America.
  • South America—The analysis region will be South America.
  • South Asia—The analysis region will be South Asia.
  • Thailand—The analysis region will be Thailand.
Legacy:

The following region names are no longer supported and will be removed in future releases. If you specify one of the deprecated region names, the tool automatically assigns a supported region name for the region.

  • Greece redirects to Europe
  • India redirects to SouthAsia
  • Oceania redirects to SouthAsia
  • SouthEastAsia redirects to SouthAsia
  • Taiwan redirects to SouthAsia

String
Reorder Stops to Find Optimal Routes
(Optional)

Specifies whether stops will be visited in the order you define or the order the tool determines will minimize overall travel.

  • Checked (True)—Stops will be visited in the order determined by the tool to minimize overall travel distance or time. It can reorder stops and account for time windows at stops. Additional parameters allow you to preserve the first or last stops while allowing the tool to reorder the intermediary stops.
  • Unchecked (False)—Stops are visited in the order you define. You can set the order of stops using a Sequence attribute in the input stops features or using the Object ID value of the stops. This is the default.

Finding the optimal stop order and the best routes is commonly known as solving the traveling salesperson problem (TSP).

Boolean
Preserve Terminal Stops
(Optional)

Specifies how terminal stops will be preserved. When Reorder Stops to Find Optimal Routes is checked (or True), you can preserve the starting or ending stops, and the tool will reorder the rest.

The first and last stops are determined by their Sequence attribute values or, if the Sequence values are null, by their Object ID values.

Preserve Terminal Stops is ignored when Reorder Stops to Find Optimal Routes is unchecked (or False).

  • Preserve First—The first stop won't be reordered. Choose this option if you are starting from a known location, such as your home, headquarters, or current location.
  • Preserve Last—The last stop won't ve reordered. The output routes can start from any stop feature but must end at the predetermined last stop.
  • Preserve First and Last—The first and last stops won't be reordered.
  • Preserve None—Any stop can be reordered, including the first and last stops. The route can start or end at any of the stop features.
String
Return to Start
(Optional)

Specifies whether routes will start and end at the same location. With this parameter, you can avoid duplicating the first stop feature and sequencing the duplicate stop at the end.

The starting location of the route is the stop feature with the lowest value in the Sequence attribute. If the Sequence values are null, it is the stop feature with the lowest Object ID value.

  • Checked (True)—The route will start and end at the first stop feature. When Reorder Stops to Find Optimal Routes and Return to Start are both checked (True), Preserve Terminal Stops must be set to Preserve First. This is the default value.
  • Unchecked (False)—The route will not start and end at the first stop feature.
Boolean
Use Time Windows
(Optional)

Specifies whether time windows will be honored. Check this parameter (set to True) if any input stops have time windows that specify when the route will reach the stop. You can add time windows to input stops by entering time values in the TimeWindowStart and TimeWindowEnd attributes.

  • Checked (True)—Time windows for the input stops, if they exist, will be honored.
  • Unchecked (False)—Time windows for the input stops, if they exist, will not be honored. This is the default value.

The tool will take slightly longer to run when Use Time Windows is checked (or True), even if no input stops have time windows, so it is recommended that you uncheck this option (set to False) if possible.

Boolean
Time of Day
(Optional)

The time and date the routes will begin.

If you are modeling the driving travel mode and specify the current date and time as the value for this parameter, the tool will use live traffic conditions to find the best routes, and the total travel time will be based on traffic conditions.

Specifying a time of day results in more accurate routes and estimations of travel times because the travel times account for the traffic conditions that are applicable for that date and time.

The Time Zone for Time of Day parameter specifies whether this time and date refer to UTC or the time zone in which the stop is located.

The tool ignores this parameter when Measurement Units isn't set to a time-based unit.

Date
Time Zone for Time of Day
(Optional)

Specifies the time zone of the Time of Day parameter.

  • Geographically Local—The Time of Day parameter refers to the time zone in which the first stop of a route is located. If you are generating many routes that start in multiple time zones, the start times are staggered in coordinated universal time (UTC). For example, a Time of Day value of 10:00 a.m., 2 January, means a start time of 10:00 a.m. eastern standard time (UTC-3:00) for routes beginning in the eastern time zone and 10:00 a.m. central standard time (UTC-4:00) for routes beginning in the central time zone. The start times are offset by one hour in UTC. The arrive and depart times and dates recorded in the output Stops feature class will refer to the local time zone of the first stop for each route.
  • UTC—The Time of Day parameter refers to UTC. Choose this option if you want to generate a route for a specific time, such as now, but aren't certain in which time zone the first stop will be located. If you are generating many routes spanning multiple time zones, the start times in UTC are simultaneous. For example, a Time of Day value of 10:00 a.m., 2 January, means a start time of 5:00 a.m. eastern standard time (UTC-5:00) for routes beginning in the eastern time zone and 4:00 a.m. central standard time (UTC-6:00) for routes beginning in the central time zone. Both routes start at 10:00 a.m. UTC. The arrive and depart times and dates recorded in the output Stops feature class will refer to UTC.
String
UTurn at Junctions
(Optional)

Specifies the U-turn policy at junctions. Allowing U-turns implies the solver can turn around at a junction and double back on the same street. Given that junctions represent street intersections and dead ends, different vehicles may be able to turn around at some junctions but not at others—it depends on whether the junction represents an intersection or dead end. To accommodate this, the U-turn policy parameter is implicitly specified by the number of edges that connect to the junction, which is known as junction valency. The acceptable values for this parameter are listed below; each is followed by a description of its meaning in terms of junction valency.

This parameter is ignored unless Travel Mode is set to Custom.

  • Allowed—U-turns are permitted at junctions with any number of connected edges. This is the default value.
  • Not Allowed—U-turns are prohibited at all junctions, regardless of junction valency. However, U-turns are still permitted at network locations even when this option is chosen, but you can set the individual network locations' CurbApproach attribute to prohibit U-turns there as well.
  • Allowed only at Dead Ends—U-turns are prohibited at all junctions except those that have only one adjacent edge (a dead end).
  • Allowed only at Intersections and Dead Ends—U-turns are prohibited at junctions where exactly two adjacent edges meet but are permitted at intersections (junctions with three or more adjacent edges) and dead ends (junctions with exactly one adjacent edge). Often, networks have extraneous junctions in the middle of road segments. This option prevents vehicles from making U-turns at these locations.
String
Point Barriers
(Optional)

Use this parameter to specify one or more points that will act as temporary restrictions or represent additional time or distance that may be required to travel on the underlying streets. For example, a point barrier can be used to represent a fallen tree along a street or a time delay spent at a railroad crossing.

The tool imposes a limit of 250 points that can be added as barriers.

When specifying point barriers, you can set properties for each, such as its name or barrier type, using the following attributes:

Name

The name of the barrier.

BarrierType

Specifies whether the point barrier restricts travel completely or adds time or distance when it is crossed. The value for this attribute is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Restriction)—Prohibits travel through the barrier. The barrier is referred to as a restriction point barrier since it acts as a restriction.

  • 2 (Added Cost)—Traveling through the barrier increases the travel time or distance by the amount specified in the Additional_Time, Additional_Distance, or AdditionalCost field. This barrier type is referred to as an added cost point barrier.

Additional_Time

The added travel time when the barrier is traversed. This field is applicable only for added-cost barriers and when the Measurement Units parameter value is time based.

This field value must be greater than or equal to zero, and its units must be the same as those specified in the Measurement Units parameter.

Additional_Distance

The added distance when the barrier is traversed. This field is applicable only for added-cost barriers and when the Measurement Units parameter value is distance based.

The field value must be greater than or equal to zero, and its units must be the same as those specified in the Measurement Units parameter.

AdditionalCost

The added cost when the barrier is traversed. This field is applicable only for added-cost barriers when the Measurement Units parameter value is neither time based nor distance based.

FullEdge

Specifies how the restriction point barriers are applied to the edge elements during the analysis. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (False)—Permits travel on the edge up to the barrier but not through it. This is the default value.
  • 1 (True)—Restricts travel anywhere on the associated edge.

CurbApproach

Specifies the direction of traffic that is affected by the barrier. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Either side of vehicle)—The barrier affects travel over the edge in both directions.
  • 1 (Right side of vehicle)—Vehicles are only affected if the barrier is on their right side during the approach. Vehicles that traverse the same edge but approach the barrier on their left side are not affected by the barrier.
  • 2 (Left side of vehicle)—Vehicles are only affected if the barrier is on their left side during the approach. Vehicles that traverse the same edge but approach the barrier on their right side are not affected by the barrier.

Because junctions are points and don't have a side, barriers on junctions affect all vehicles regardless of the curb approach.

The CurbApproach attribute works with both types of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider a facility on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach a facility from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, to arrive at a facility and not have a lane of traffic between the vehicle and the facility, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

Bearing

The direction in which a point is moving. The units are degrees and are measured clockwise from true north. This field is used in conjunction with the BearingTol field.

Bearing data is usually sent automatically from a mobile device equipped with a GPS receiver. Try to include bearing data if you are loading an input location that is moving, such as a pedestrian or a vehicle.

Using this field tends to prevent adding locations to the wrong edges, which can occur when a vehicle is near an intersection or an overpass, for example. Bearing also helps the tool determine on which side of the street the point is.

BearingTol

The bearing tolerance value creates a range of acceptable bearing values when locating moving points on an edge using the Bearing field. If the Bearing field value is within the range of acceptable values that are generated from the bearing tolerance on an edge, the point can be added as a network location there; otherwise, the closest point on the next-nearest edge is evaluated.

The units are in degrees, and the default value is 30. Values must be greater than 0 and less than 180. A value of 30 means that when Network Analyst attempts to add a network location on an edge, a range of acceptable bearing values is generated 15 degrees to either side of the edge (left and right) and in both digitized directions of the edge.

NavLatency

This field is only used in the solve process if the Bearing and BearingTol fields also have values; however, entering a NavLatency field value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much cost is expected to elapse from the moment GPS information is sent from a moving vehicle to a server and the moment the processed route is received by the vehicle's navigation device.

The units of NavLatency are the same as the units of the impedance attribute.

Feature Set
Line Barriers
(Optional)

Use this parameter to specify one or more lines that prohibit travel anywhere the lines intersect the streets. For example, a parade or protest that blocks traffic across several street segments can be modeled with a line barrier. A line barrier can also quickly fence off several roads from being traversed, thereby channeling possible routes away from undesirable parts of the street network.

The tool imposes a limit on the number of streets you can restrict using the Line Barriers parameter. While there is no limit to the number of lines you can specify as line barriers, the combined number of streets intersected by all the lines cannot exceed 500.

When specifying the line barriers, you can set name and barrier type properties for each using the following attributes:

Name

The name of the barrier.

Feature Set
Polygon Barriers
(Optional)

Use this parameter to specify polygons that either completely restrict travel or proportionately scale the time or distance required to travel on the streets intersected by the polygons.

The service imposes a limit on the number of streets you can restrict using the Polygon Barriers parameter. While there is no limit to the number of polygons you can specify as polygon barriers, the combined number of streets intersected by all the polygons cannot exceed 2,000.

When specifying the polygon barriers, you can set properties for each, such as its name or barrier type, using the following attributes:

Name

The name of the barrier.

BarrierType

Specifies whether the barrier restricts travel completely or scales the cost (such as time or distance) for traveling through it. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Restriction)—Prohibits traveling through any part of the barrier. The barrier is referred to as a restriction polygon barrier since it prohibits traveling on streets intersected by the barrier. One use of this type of barrier is to model floods covering areas of the street that make traveling on those streets impossible.

  • 1 (Scaled Cost)—Scales the cost (such as travel time or distance) required to travel the underlying streets by a factor specified using the ScaledTimeFactor or ScaledDistanceFactor field. If the streets are partially covered by the barrier, the travel time or distance is apportioned and then scaled. For example, a factor of 0.25 means that travel on underlying streets is expected to be four times faster than normal. A factor of 3.0 means it is expected to take three times longer than normal to travel on underlying streets. This barrier type is referred to as a scaled-cost polygon barrier. It can be used to model storms that reduce travel speeds in specific regions, for example.

ScaledTimeFactor

This is the factor by which the travel time of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

This field is applicable only for scaled-cost barriers and when the Measurement Units parameter is time-based.

ScaledDistanceFactor

This is the factor by which the distance of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

This field is applicable only for scaled-cost barriers and when the Measurement Units parameter is distance-based.

ScaledCostFactor

This is the factor by which the cost of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

This field is applicable only for scaled-cost barriers when the Measurement Units parameter is neither time-based nor distance-based.

Feature Set
Use Hierarchy
(Optional)

Specifies whether hierarchy will be used when finding the shortest paths between stops.

  • Checked (True in Python)—Hierarchy will be used when finding routes. When hierarchy is used, the tool identifies higher-order streets (such as freeways) before lower-order streets (such as local roads) and can be used to simulate the driver preference of traveling on freeways instead of local roads even if that means a longer trip. This is especially useful when finding routes to faraway locations, because drivers on long-distance trips tend to prefer traveling on freeways, where stops, intersections, and turns can be avoided. Using hierarchy is computationally faster, especially for long-distance routes, as the tool identifies the best route from a relatively smaller subset of streets.
  • Unchecked (False in Python)—Hierarchy will not be used when finding routes. If hierarchy is not used, the tool considers all the streets and doesn't necessarily identify higher-order streets when finding the route. This is often used when finding short routes in a city.

The tool automatically reverts to using hierarchy if the straight-line distance between facilities and demand points is greater than 50 miles (80.46 kilometers), even if this parameter is unchecked (set to False in Python).

This parameter is ignored unless Travel Mode is set to Custom. When modeling a custom walking mode, it is recommended that you turn off hierarchy since hierarchy is designed for motorized vehicles.

Boolean
Restrictions
(Optional)

The restrictions that will be honored by the tool when finding the best routes.

A restriction represents a driving preference or requirement. In most cases, restrictions cause roads to be prohibited. For instance, using the Avoid Toll Roads restriction will result in a route that will include toll roads only when it is required to travel on toll roads to visit an incident or a facility. Height Restriction makes it possible to route around any clearances that are lower than the height of the vehicle. If you are carrying corrosive materials on the vehicle, using the Any Hazmat Prohibited restriction prevents hauling the materials along roads where it is marked illegal to do so.

Note:

Some restrictions require an additional value to be specified for their use. This value must be associated with the restriction name and a specific parameter intended to work with the restriction. You can identify such restrictions if their names appear in the AttributeName column of the Attribute Parameter Values parameter. Specify the ParameterValue field for the Attribute Parameter Values parameter for the restriction to be correctly used when finding traversable roads.

Note:

Some restrictions are supported only in certain countries; their availability is stated by region in the list below. Of the restrictions that have limited availability within a region, you can determine whether the restriction is available in a particular country by reviewing the table in the Country list section of Network analysis coverage. If a country has a value of Yes in the Logistics Attribute column, the restriction with select availability in the region is supported in that country. If you specify restriction names that are not available in the country where the incidents are located, the service ignores the invalid restrictions. The service also ignores restrictions when the Restriction Usage attribute parameter value is between 0 and 1 (see the Attribute Parameter Value parameter). It prohibits all restrictions when the Restriction Usage parameter value is greater than 0.

The service supports the following restrictions:

  • Any Hazmat Prohibited—The results will not include roads where transporting any kind of hazardous material is prohibited. Availability: Select countries in North America and Europe
  • Avoid Carpool Roads—The results will avoid roads that are designated exclusively for car pool (high-occupancy) vehicles. Availability: All countries

  • Axle Count Restriction—The results will not include roads where trucks with the specified number of axles are prohibited. The number of axles can be specified using the Number of Axles restriction parameter.Availability: Select countries in North America and Europe
  • Driving a Bus—The results will not include roads where buses are prohibited. Using this restriction will also ensure that the results will honor one-way streets. Availability: All countries
  • Driving a Taxi—The results will not include roads where taxis are prohibited. Using this restriction will also ensure that the results will honor one-way streets. Availability: All countries
  • Driving a Truck—The results will not include roads where trucks are prohibited. Using this restriction will also ensure that the results will honor one-way streets. Availability: All countries

Note:

The values you provide for this parameter are ignored unless Travel Mode is set to Custom.

String
Attribute Parameter Values
(Optional)

Use this parameter to specify additional values required by an attribute or restriction, such as to specify whether the restriction prohibits, avoids, or prefers travel on restricted roads. If the restriction is meant to avoid or prefer roads, you can further specify the degree to which they are avoided or preferred using this parameter. For example, you can choose to never use toll roads, avoid them as much as possible, or prefer them.

Note:

The values you provide for this parameter are ignored unless Travel Mode is set to Custom.

If you specify the Attribute Parameter Values parameter from a feature class, the field names on the feature class must match the fields as follows:

  • AttributeName—The name of the restriction.
  • ParameterName—The name of the parameter associated with the restriction. A restriction can have one or more ParameterName field values based on its intended use.
  • ParameterValue—The value for ParameterName used by the tool when evaluating the restriction.

The Attribute Parameter Values parameter is dependent on the Restrictions parameter. The ParameterValue field is applicable only if the restriction name is specified as the value for the Restrictions parameter.

In Attribute Parameter Values, each restriction (listed as AttributeName) has a ParameterName field value, Restriction Usage, that specifies whether the restriction prohibits, avoids, or prefers travel on the roads associated with the restriction as well as the degree to which the roads are avoided or preferred. The Restriction Usage ParameterName can be assigned any of the following string values or their equivalent numeric values listed in the parentheses:

  • PROHIBITED (-1)—Travel on the roads using the restriction is completely prohibited.
  • AVOID_HIGH (5)—It is highly unlikely the tool will include in the route the roads that are associated with the restriction.
  • AVOID_MEDIUM (2)—It is unlikely the tool will include in the route the roads that are associated with the restriction.
  • AVOID_LOW (1.3)—It is somewhat unlikely the tool will include in the route the roads that are associated with the restriction.
  • PREFER_LOW (0.8)—It is somewhat likely the tool will include in the route the roads that are associated with the restriction.
  • PREFER_MEDIUM (0.5)—It is likely the tool will include in the route the roads that are associated with the restriction.
  • PREFER_HIGH (0.2)—It is highly likely the tool will include in the route the roads that are associated with the restriction.

In most cases, you can use the default value, PROHIBITED, as the Restriction Usage value if the restriction is dependent on a vehicle characteristic such as vehicle height. However, in some cases, the Restriction Usage value depends on your routing preferences. For example, the Avoid Toll Roads restriction has the default value of AVOID_MEDIUM for the Restriction Usage attribute. This means that when the restriction is used, the tool will route around toll roads when it can. AVOID_MEDIUM also indicates how important it is to avoid toll roads when finding the best route; it has a medium priority. Choosing AVOID_LOW puts lower importance on avoiding tolls; choosing AVOID_HIGH instead gives it a higher importance and makes it more acceptable for the service to generate longer routes to avoid tolls. Choosing PROHIBITED entirely disallows travel on toll roads, making it impossible for a route to travel on any portion of a toll road. Keep in mind that avoiding or prohibiting toll roads, and avoiding toll payments, is the objective for some. In contrast, others prefer to drive on toll roads, because avoiding traffic is more valuable to them than the money spent on tolls. In the latter case, choose PREFER_LOW, PREFER_MEDIUM, or PREFER_HIGH as the value for Restriction Usage. The higher the preference, the farther the tool will go to travel on the roads associated with the restriction.

Record Set
Route Shape
(Optional)

Specifies the type of route features that will be output by the tool.

When the Route Shape parameter is set to True Shape or True Shape with Measures, the generalization of the route shape can be further controlled using the appropriate value for the Route Line Simplification Tolerance parameter.

No matter which value you choose for the Route Shape parameter, the best route is always determined by minimizing the travel time or the travel distance, never using the straight-line distance between stops. This means that only the route shapes are different, not the underlying streets that are searched when finding the route.

  • True Shape—The exact shape of the resulting route that is based on the underlying streets will be returned.
  • True Shape with Measures—The exact shape of the resulting route that is based on the underlying streets will be returned. Additionally, construct measures so the shape can be used in linear referencing. The measurements increase from the first stop and record the cumulative travel time or travel distance in the units specified by the Measurement Units parameter.
  • Straight Line—A straight line between two stops will be returned.
  • None—No shapes for the routes will be returned. This value can be useful, and return results quickly, when you are only interested in determining the total travel time or travel distance of a route.
String
Route Line Simplification Tolerance
(Optional)

The amount by which the geometry of the output lines will be simplified for routes, directions, and route edges.

The tool ignores this parameter if the Route Shape parameter isn't set to True Shape.

Simplification maintains critical points on a route, such as turns at intersections, to define the essential shape of the route and removes other points. The simplification distance you specify is the maximum allowable offset that the simplified line can deviate from the original line. Simplifying a line reduces the number of vertices that are part of the route geometry. This improves the tool processing time.

Linear Unit
Populate Route Edges
(Optional)

Specifies whether edges for each route will be generated. Route edges represent the individual street features or other similar features that are traversed by a route. The output Route Edges layer is commonly used to determine which streets or paths are traveled on the most or least by the resultant routes.

  • Checked (True)—Route edges will be generated, and the output Route Edges layer will be populated with line features.
  • Unchecked (False)—Route edges will not be generated, and an empty output Route Edges layer will be returned.
Boolean
Populate Directions
(Optional)

Specifies whether the tool will generate driving directions for each route.

  • Checked (True in Python)—Directions will be generated and configured based on the values of the Directions Language, Directions Style Name, and Directions Distance Units parameters.
  • Unchecked (False in Python)—Directions will not be generated, and the tool will return an empty Directions layer.

Boolean
Directions Language
(Optional)

The language that will be used when generating travel directions.

This parameter is used only when the Populate Directions parameter is checked (True in Python).

The parameter value can be specified using one of the following two- or five-character language codes:

  • ar—Arabic
  • bg—Bulgarian
  • bs—Bosnian
  • ca—Catalan
  • cs—Czech
  • da—Danish
  • de—German
  • el—Greek
  • en—English
  • es—Spanish
  • et—Estonian
  • fi—Finnish
  • fr—French
  • he—Hebrew
  • hr—Croatian
  • hu—Hungarian
  • id—Indonesian
  • it—Italian
  • ja—Japanese
  • ko—Korean
  • lt—Lithuanian
  • lv—Latvian
  • nb—Norwegian
  • nl—Dutch
  • pl—Polish
  • pt-BR—Portuguese (Brazil)
  • pt-PT—Portuguese (Portugal)
  • ro—Romanian
  • ru—Russian
  • sk—Slovak
  • sl—Slovenian
  • sr—Serbian
  • sv—Swedish
  • th—Thai
  • tr—Turkish
  • uk—Ukrainian
  • vi—Vietnamese
  • zh-CN—Chinese (China)
  • zh-HK—Chinese (Hong Kong)
  • zh-TW—Chinese (Taiwan)

The tool first searches for an exact match for the specified language including any language localization. If an exact match is not found, it tries to match the language family. If a match is still not found, the tool returns the directions using the default language, English. For example, if the directions language is specified as es-MX (Mexican Spanish), the tool will return the directions in Spanish, as it supports the es language code but not es-MX.

Caution:

If a language supports localization, such as Brazilian Portuguese (pt-BR) and European Portuguese (pt-PT), specify the language family and the localization. If you only specify the language family, the tool will not match the language family and instead return directions in the default language, English. For example, if the directions language specified is pt, the tool will return the directions in English since it cannot determine whether the directions should be returned in pt-BR or pt-PT.

String
Directions Distance Units
(Optional)

Specifies the units that will display travel distance in the driving directions. This parameter is used only when the Populate Directions parameter is checked (True in Python).

  • Miles—The linear unit will be miles.
  • Kilometers—The linear unit will be kilometers.
  • Meters—The linear unit will be meters.
  • Feet—The linear unit will be feet.
  • Yards—The linear unit will be yards.
  • Nautical Miles—The linear unit will be nautical miles.
String
Directions Style Name
(Optional)

Specifies the name of the formatting style for the directions. This parameter is used only when the Populate Directions parameter is checked (True in Python).

  • Network Analyst Desktop—The style will be turn-by-turn directions suitable for printing.
  • Network Analyst Navigation—The style will be turn-by-turn directions designed for an in-vehicle navigation device.
String
Travel Mode
(Optional)

The mode of transportation that will be modeled in the analysis. Travel modes are managed in ArcGIS Online and can be configured by the administrator of your organization to reflect the organization's workflows. Specify the name of a travel mode that is supported by your organization.

To get a list of supported travel mode names, run the Get Travel Modes tool from the Utilities toolbox under the same GIS Server connection you used to access the tool. The Get Travel Modes tool adds a table, Supported Travel Modes, to the application. Any value in the Travel Mode Name field from the Supported Travel Modes table can be specified as input. You can also specify the value from the Travel Mode Settings field as input. This speeds up tool execution, as the tool does not have to find the settings based on the travel mode name.

The default value, Custom, allows you to configure a custom travel mode using the custom travel mode parameters (UTurn at Junctions, Use Hierarchy, Restrictions, Attribute Parameter Values, and Impedance). The default values of the custom travel mode parameters model traveling by car. You can also choose Custom and set the custom travel mode parameters listed above to model a pedestrian with a fast walking speed or a truck with a given height, weight, and cargo of certain hazardous materials. You can try different settings to get the analysis results you want. Once you have identified the analysis settings, work with your organization's administrator and save these settings as part of a new or existing travel mode so that everyone in your organization can run the analysis with the same settings.

Caution:

When you choose Custom, the values you set for the custom travel mode parameters are included in the analysis. Specifying another travel mode, as defined by your organization, causes any values you set for the custom travel mode parameters to be ignored; the tool overrides them with values from the specified travel mode.

String
Impedance
(Optional)

Specifies the impedance, which is a value that represents the effort or cost of traveling along road segments or on other parts of the transportation network.

Travel time is an impedance: a car may take 1 minute to travel a mile along an empty road. Travel times can vary by travel mode—a pedestrian may take more than 20 minutes to walk the same mile, so it is important to choose the right impedance for the travel mode you are modeling.

Travel distance can also be an impedance; the length of a road in kilometers can be thought of as impedance. Travel distance in this sense is the same for all modes—a kilometer for a pedestrian is also a kilometer for a car. (What may change is the pathways on which the different modes are allowed to travel, which affects distance between points, and this is modeled by travel mode settings.)

Choose from the following impedance values:

If you choose a time-based impedance, such as TravelTime, TruckTravelTime, Minutes, TruckMinutes, or WalkTime, the Measurement Units parameter must be set to a time-based value. If you choose a distance-based impedance, such as Miles or Kilometers, Measurement Units must be distance based.

  • Travel Time—Historical and live traffic data is used. This option is good for modeling the time it takes automobiles to travel along roads at a specific time of day using live traffic speed data where available. When using TravelTime, you can optionally set the TravelTime::Vehicle Maximum Speed (km/h) attribute parameter to specify the physical limitation of the speed the vehicle is capable of traveling.
  • Minutes—Live traffic data is not used, but historical average speeds for automobiles data is used.
  • Truck Travel Time—Historical and live traffic data is used, but the speed is capped at the posted truck speed limit. This is good for modeling the time it takes for the trucks to travel along roads at a specific time. When using TruckTravelTime, you can optionally set the TruckTravelTime::Vehicle Maximum Speed (km/h) attribute parameter to specify the physical limitation of the speed the truck is capable of traveling.
  • Truck Minutes—Live traffic data is not used, but the smaller of the historical average speeds for automobiles and the posted speed limits for trucks is used.
  • Walk Time—The default is a speed of 5 km/hr on all roads and paths, but this can be configured through the WalkTime::Walking Speed (km/h) attribute parameter.
  • Miles—Length measurements along roads are stored in miles and can be used for performing analysis based on shortest distance.
  • Kilometers—Length measurements along roads are stored in kilometers and can be used for performing analysis based on shortest distance.
  • Time At One Kilometer Per Hour—The default is a speed of 1 km/hr on all roads and paths. The speed cannot be changed using any attribute parameter.
  • Drive Time—Travel times for a car are modeled. These travel times are dynamic and fluctuate according to traffic flows in areas where traffic data is available. This is the default value.
  • Truck Time—Travel times for a truck are modeled. These travel times are static for each road and don't fluctuate with traffic.
  • Walk Time—Travel times for a pedestrian are modeled.
  • Travel Distance—Length measurements along roads and paths are stored. To model walk distance, choose this option and ensure that Walking is set for the Restriction parameter. Similarly, to model drive or truck distance, choose Travel Distance here and set the appropriate restrictions so the vehicle travels only on roads where it is permitted to do so.
Caution:

The value you provide for this parameter is ignored unless Travel Mode is set to Custom, which is the default value.

Legacy:

Drive Time, Truck Time, Walk Time, and Travel Distance impedance values are no longer supported and will be removed in a future release. If you use one of these values, the tool uses the value of the Time Impedance parameter for time-based values and the Distance Impedance parameter for distance-based values.

String
Time Zone for Time Windows
(Optional)

Specifies the time zone that will be used for the time window values on stops. The time windows are specified as part of TimeWindowStart and TimeWindowEnd fields on stops. This parameter is applicable only when the Use Time Windows parameter is checked (set to True).

  • Geographically Local—The time window values associated with the stops are in the time zone in which the stops are located. For example, if the stop is located in an area that follows eastern standard time and has time window values of 8 AM and 10 AM, the time window values will be treated as 8 a.m. and 10 a.m eastern standard time. This is the default.
  • UTC—The time window values associated with the stops are in coordinated universal time (UTC). For example, if the stop is located in an area that follows eastern standard time and has time window values of 8 AM and 10 AM, the time window values will be treated as 12 p.m and 2 p.m eastern standard time, assuming eastern standard time is obeying daylight saving time. Specifying the time window values in UTC is useful if you do not know the time zone in which the stops are located or if you have stops in multiple time zones and you want all the time windows to start simultaneously.
String
Save Output Network Analysis Layer
(Optional)

Specifies whether the analysis settings will be saved as a network analysis layer file. You cannot directly work with this file even when you open the file in an ArcGIS Desktop application such as ArcMap. It is meant to be sent to Esri Technical Support to diagnose the quality of results returned from the tool.

  • Checked (True in Python)—The output will be saved as a network analysis layer file. The file will be downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the value for the Output Network Analysis Layer parameter in the entry corresponding to the tool service in the geoprocessing history of the project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu of the Output Network Analysis Layer parameter in the entry corresponding to the tool service in the Geoprocessing Results window.
  • Unchecked (False in Python)—The output will not be saved as a network analysis layer file. This is the default.

Boolean
Overrides
(Optional)

Note:

This parameter is for internal use only.

String
Save Route Data
(Optional)

Specifies whether the output will include a .zip file that contains a file geodatabase with the inputs and outputs of the analysis in a format that can be used to share route layers with ArcGIS Online or Portal for ArcGIS.

  • Checked (True in Python)—The route data will be saved as a .zip file. The file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the value for the Output Route Data parameter in the entry corresponding to the tool operation in the geoprocessing history of the project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu of the Output Route Data parameter in the entry corresponding to the tool operation in the Geoprocessing Results window.
  • Unchecked (False in Python)—The route data will not be saved as a .zip file. This is the default.

Boolean
Time Impedance
(Optional)

The time-based impedance value represents the travel time along road segments or on other parts of the transportation network.

  • Minutes—Time impedance will be minutes.
  • Travel Time—Time impedance will be travel time.
  • Time At One Kilometer Per Hour—Time impedance will be time at one kilometer per hour.
  • Walk Time—Time impedance will be walk time.
  • Truck Minutes—Time impedance will be truck minutes.
  • Truck Travel Time—Time impedance will be truck travel time.
Note:
If the impedance for the travel mode, as specified using the Impedance parameter, is time based, the values for the Time Impedance and Impedance parameters must be identical. Otherwise, the service will return an error.
String
Distance Impedance
(Optional)

The distance-based impedance value represents the travel distance along road segments or on other parts of the transportation network.

  • Miles—Distance impedance will be miles.
  • Kilometers—Distance impedance will be kilometers.
Note:
If the impedance for the travel mode, as specified using the Impedance parameter, is distance based, the values for the Distance Impedance and Impedance parameters must be identical. Otherwise, the service will return an error.
String
Output Format
(Optional)

Specifies the format in which the output features will be returned.

When a file-based output format, such as JSON File or GeoJSON File, is specified, no outputs will be added to the display because the application, such as ArcMap or ArcGIS Pro, cannot draw the contents of the result file. Instead, the result file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the value for the Output Result File parameter in the entry corresponding to the tool operation in the geoprocessing history of the project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu of the Output Result File parameter in the entry corresponding to the tool operation in the Geoprocessing Results window.

  • Feature Set—The output features will be returned as feature classes and tables. This is the default.
  • JSON File—The output features will be returned as a compressed file containing the JSON representation of the outputs. When this option is specified, the output is a single file (with a .zip extension) that contains one or more JSON files (with a .json extension) for each of the outputs created by the service.
  • GeoJSON File—The output features will be returned as a compressed file containing the GeoJSON representation of the outputs. When this option is specified, the output is a single file (with a .zip extension) that contains one or more GeoJSON files (with a .geojson extension) for each of the outputs created by the service.
String
Ignore Invalid Locations
(Optional)

Specifies whether invalid input locations will be ignored.

  • Checked—Network locations that are unlocated will be ignored and the analysis will run using valid network locations only. The analysis will also continue if locations are on non-traversable elements or have other errors. This is useful if you know the network locations are not all correct, but you want to run the analysis with the network locations that are valid. This is the default.
  • Unchecked—Invalid locations will not be ignored. Do not run the analysis if there are invalid locations. Correct the invalid locations and rerun the analysis.
Boolean
Locate Settings
(Optional)

Use this parameter to specify settings that affect how inputs are located, such as the maximum search distance to use when locating the inputs on the network or the network sources being used for locating.

Learn more about locating inputs

The locator JSON object has the following properties:

  • tolerance and toleranceUnits—Allows you to control the maximum search distance when locating inputs. If no valid network location is found within this distance, the input features will be considered unlocated. A small search tolerance decreases the likelihood of locating on the wrong street but increases the likelihood of not finding any valid network location. The toleranceUnits parameter value can be specified as one of the following values:
    • esriCentimeters
    • esriDecimalDegrees
    • esriDecimeters
    • esriFeet
    • esriInches
    • esriIntFeet
    • esriIntInches
    • esriIntMiles
    • esriIntNauticalMiles
    • esriIntYards
    • esriKilometers
    • esriMeters
    • esriMiles
    • esriMillimeters
    • esriNauticalMiles
    • esriYards
  • sources— Allows you to control which network source can be used for locating. For example, you can configure the analysis to locate inputs on streets but not on sidewalks. The list of possible sources on which to locate is specific to the network dataset this service references. Only the sources that are present in the sources array are used for locating. Sources is specified as an array of objects each having the following property:
    • name—The name of the network source feature class that can be used for locating inputs
  • allowAutoRelocate—Allows you to control whether inputs with existing network location fields can be automatically relocated when solving to ensure valid, routable location fields for the analysis. If the value is true, points located on restricted network elements and points affected by barriers will be relocated to the closest routable location. If the value is false, network location fields will be used as is even if the points are unreachable, and this may cause the solve to fail. Even if the value is false, inputs with no location fields or incomplete location fields will be located during the solve operation.
Note:
Currently, you can't specify different source names for the sources array. Also, allowAutoRelocate is always set to true since the service does not support location fields.

The parameter value is specified as a JSON object. The JSON object allows you to specify a locator JSON for all input feature in the analysis, or you can specify an override for a particular input. The override allows you to have different settings for each analysis input. For example, you can disallow stops to locate on highway ramps and allow point barriers to locate on highway ramps. When specifying the Locate_Settings JSON, you must provide the tolerance, toleranceUnits, and allowAutoRelocate properties. If you need to provide a different locator JSON for a particular input class, you must include the overrides property for that input. The property name must match the input parameter name. The locator JSON for a particular input doesn't need to include all the properties; you only need to include the properties that are different from the default locator JSON properties.

NameExplanationData Type
Stops

Specifies the locations the output route or routes will visit.

You can add up to 10,000 stops and assign up to 150 stops to a single route. (Assign stops to routes using the RouteName attribute.)

When specifying the stops, you can set properties for each—such as its name or service time— using the following attributes:

Name

The name of the stop. The name is used in the driving directions. If no name is provided, a unique name prefixed with Location is automatically generated in the output stops, routes, and directions.

RouteName

The name of the route to which the stop belongs. Stops with the same RouteName value are grouped together.

You can group up to 150 stops into one route.

Sequence

The output routes will visit the stops in the order you specify with this attribute. In a group of stops that have the same RouteName value, the sequence number should be greater than 0 but not greater than the total number of stops. Also, the sequence number should not be duplicated.

If Reorder Stops To Find Optimal Routes is checked (True), all but possibly the first and last sequence values for each route name are ignored so the tool can find the sequence that minimizes overall travel for each route. (The settings for Preserve Ordering of Stops and Return to Start determine whether the first or last sequence values for each route are ignored.)

AdditionalTime

The amount of time spent at the stop, which is added to the total time of the route. The default value is 0.

The units for this attribute value are specified by the Measurement Units parameter. The attribute value is included in the analysis only when the measurement units are time based.

You can account for the extra time it takes at the stop to complete a task, such as to repair an appliance, deliver a package, or inspect the premises.

AdditionalDistance

The extra distance traveled at the stops, which is added to the total distance of the route. The default value is 0.

The units for this attribute value are specified by the Measurement Units parameter. The attribute value is included in the analysis only when the measurement units are distance based.

Generally, the location of a stop, such as a home, isn't exactly on the street; it is set back somewhat from the road. This attribute value can be used to model the distance between the actual stop location and its location on the street if it is important to include that distance in the total travel distance.

AdditionalCost

The extra cost spent at the stop, which is added to the total cost of the route. The default value is 0.

This attribute value should be used when the travel mode for the analysis uses an impedance attribute that is neither time based nor distance based. The units for the attribute values are interpreted to be in unknown units.

TimeWindowStart

The earliest time the stop can be visited. By specifying a start and end time for a stop's time window, you are defining when a route will visit the stop. When the travel mode for the analysis uses an impedance attribute that is time based, specifying time-window values will cause the analysis to find a solution that minimizes overall travel and reaches the stop within the prescribed time window.

Ensure that you specify the value as a date and time value, such as 8/12/2015 12:15 PM.

When solving a problem that spans multiple time zones, time-window values refer to the time zone in which the stop is located.

This field can contain a null value; a null value indicates that a route can arrive at any time before the time indicated in the TimeWindowEnd attribute. If a null value is also present in TimeWindowEnd, a route can visit the stop at any time.

TimeWindowEnd

The latest time the stop can be visited. By specifying a start and end time for a stop's time window, you are defining when a route will visit the stop. When the travel mode for the analysis uses an impedance attribute that is time based, specifying time-window values will cause the analysis to find a solution that minimizes overall travel and reaches the stop within the prescribed time window.

Ensure that you specify the value as a date and time value, such as 8/12/2015 12:15 PM.

When solving a problem that spans multiple time zones, time-window values refer to the time zone in which the stop is located.

This field can contain a null value; a null value indicates that a route can arrive at any time after the time indicated in the TimeWindowStart attribute. If a null value is also present in TimeWindowStart, a route can visit the stop at any time.

CurbApproach

Specifies the direction a vehicle can arrive at and depart from the stop. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Either side of vehicle)—The vehicle can approach and depart the stop in either direction, so a U-turn is allowed at the stop. This setting can be used if it is possible and practical for a vehicle to turn around at the stop. This decision may depend on the width of the road and the amount of traffic or whether the stop has a parking lot where vehicles can enter and turn around.
  • 1 (Right side of vehicle)—When the vehicle approaches and departs the stop, the curb must be on the right side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the right-hand side.
  • 2 (Left side of vehicle)—When the vehicle approaches and departs the stop, the curb must be on the left side of the vehicle. A U-turn is prohibited. This is typically used for vehicles such as buses that must arrive with the bus stop on the left-hand side.
  • 3 (No U-Turn)—When the vehicle approaches the stop, the curb can be on either side of the vehicle; however, the vehicle must depart without turning around.

The CurbApproach attribute works with both national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider a stop on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach a stop from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, to arrive at a stop and not have a lane of traffic between the vehicle and the stop, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

LocationType

Specifies the stop type. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Stop)—A location that the route will visit. This is the default.
  • 1 (Waypoint)—A location that the route will travel through without making a stop. Waypoints can be used to force the route to take a specific path (to go through the waypoint) without being considered an actual stop. Waypoints do not appear in directions.

Bearing

The direction in which a point is moving. The units are degrees and are measured clockwise from true north. This field is used in conjunction with the BearingTol field.

Bearing data is usually sent automatically from a mobile device equipped with a GPS receiver. Try to include bearing data if you are loading an input location that is moving, such as a pedestrian or a vehicle.

Using this field tends to prevent adding locations to the wrong edges, which can occur when a vehicle is near an intersection or an overpass, for example. Bearing also helps the tool determine on which side of the street the point is.

BearingTol

The bearing tolerance value creates a range of acceptable bearing values when locating moving points on an edge using the Bearing field. If the Bearing field value is within the range of acceptable values that are generated from the bearing tolerance on an edge, the point can be added as a network location there; otherwise, the closest point on the next-nearest edge is evaluated.

The units are in degrees, and the default value is 30. Values must be greater than 0 and less than 180. A value of 30 means that when Network Analyst attempts to add a network location on an edge, a range of acceptable bearing values is generated 15 degrees to either side of the edge (left and right) and in both digitized directions of the edge.

NavLatency

This field is only used in the solve process if the Bearing and BearingTol fields also have values; however, entering a NavLatency field value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much cost is expected to elapse from the moment GPS information is sent from a moving vehicle to a server and the moment the processed route is received by the vehicle's navigation device.

The units of NavLatency are the same as the units of the impedance attribute.

Feature Set
Measurement_Units

Specifies the units that will be used to measure and report the total travel time or travel distance for the output routes.

This parameter value determines whether distance or time will be measured to find the best routes. To minimize travel time for the travel mode (driving or walking time, for instance), specify a time unit. To minimize travel distance for the travel mode, specify a distance unit. This value also determines the units that will be used for total time or distance in the results.

  • Meters—The linear unit will be meters.
  • Kilometers—The linear unit will be kilometers.
  • Feet—The linear unit will be feet.
  • Yards—The linear unit will be yards.
  • Miles—The linear unit will be miles.
  • NauticalMiles—The linear unit will be nautical miles.
  • Seconds—The time unit will be seconds.
  • Minutes—The time unit will be minutes.
  • Hours—The time unit will be hours.
  • Days—The time unit will be days.
String
Analysis_Region
(Optional)

The region in which the analysis will be performed. If a value is not specified for this parameter, the tool will automatically calculate the region name based on the location of the input points. Setting the name of the region is required only if the automatic detection of the region name is not accurate for the inputs.

To specify a region, use one of the following values:

  • Europe—The analysis region will be Europe.
  • Japan—The analysis region will be Japan.
  • Korea—The analysis region will be Korea.
  • MiddleEastAndAfrica—The analysis region will be Middle East and Africa.
  • NorthAmerica—The analysis region will be North America.
  • SouthAmerica—The analysis region will be South America.
  • SouthAsia—The analysis region will be South Asia.
  • Thailand—The analysis region will be Thailand.
Legacy:

The following region names are no longer supported and will be removed in future releases. If you specify one of the deprecated region names, the tool automatically assigns a supported region name for the region.

  • Greece redirects to Europe
  • India redirects to SouthAsia
  • Oceania redirects to SouthAsia
  • SouthEastAsia redirects to SouthAsia
  • Taiwan redirects to SouthAsia

String
Reorder_Stops_to_Find_Optimal_Routes
(Optional)

Specifies whether stops will be visited in the order you define or the order the tool determines will minimize overall travel.

  • Checked (True)—Stops will be visited in the order determined by the tool to minimize overall travel distance or time. It can reorder stops and account for time windows at stops. Additional parameters allow you to preserve the first or last stops while allowing the tool to reorder the intermediary stops.
  • Unchecked (False)—Stops are visited in the order you define. You can set the order of stops using a Sequence attribute in the input stops features or using the Object ID value of the stops. This is the default.

Finding the optimal stop order and the best routes is commonly known as solving the traveling salesperson problem (TSP).

Boolean
Preserve_Terminal_Stops
(Optional)

Specifies how terminal stops will be preserved. When Reorder Stops to Find Optimal Routes is checked (or True), you can preserve the starting or ending stops, and the tool will reorder the rest.

The first and last stops are determined by their Sequence attribute values or, if the Sequence values are null, by their Object ID values.

  • Preserve First—The first stop won't be reordered. Choose this option if you are starting from a known location, such as your home, headquarters, or current location.
  • Preserve Last—The last stop won't ve reordered. The output routes can start from any stop feature but must end at the predetermined last stop.
  • Preserve First and Last—The first and last stops won't be reordered.
  • Preserve None—Any stop can be reordered, including the first and last stops. The route can start or end at any of the stop features.

Preserve Terminal Stops is ignored when Reorder Stops to Find Optimal Routes is unchecked (or False).

String
Return_to_Start
(Optional)

Specifies whether routes will start and end at the same location. With this parameter, you can avoid duplicating the first stop feature and sequencing the duplicate stop at the end.

The starting location of the route is the stop feature with the lowest value in the Sequence attribute. If the Sequence values are null, it is the stop feature with the lowest Object ID value.

  • Checked (True)—The route will start and end at the first stop feature. When Reorder Stops to Find Optimal Routes and Return to Start are both checked (True), Preserve Terminal Stops must be set to Preserve First. This is the default value.
  • Unchecked (False)—The route will not start and end at the first stop feature.
Boolean
Use_Time_Windows
(Optional)

Specifies whether time windows will be honored. Check this parameter (set to True) if any input stops have time windows that specify when the route will reach the stop. You can add time windows to input stops by entering time values in the TimeWindowStart and TimeWindowEnd attributes.

  • Checked (True)—Time windows for the input stops, if they exist, will be honored.
  • Unchecked (False)—Time windows for the input stops, if they exist, will not be honored. This is the default value.

The tool will take slightly longer to run when Use Time Windows is checked (or True), even if no input stops have time windows, so it is recommended that you uncheck this option (set to False) if possible.

Boolean
Time_of_Day
(Optional)

The time and date the routes will begin.

If you are modeling the driving travel mode and specify the current date and time as the value for this parameter, the tool will use live traffic conditions to find the best routes, and the total travel time will be based on traffic conditions.

Specifying a time of day results in more accurate routes and estimations of travel times because the travel times account for the traffic conditions that are applicable for that date and time.

The Time Zone for Time of Day parameter specifies whether this time and date refer to UTC or the time zone in which the stop is located.

The tool ignores this parameter when Measurement Units isn't set to a time-based unit.

Date
Time_Zone_for_Time_of_Day
(Optional)

Specifies the time zone of the Time of Day parameter.

  • Geographically Local—The Time of Day parameter refers to the time zone in which the first stop of a route is located. If you are generating many routes that start in multiple time zones, the start times are staggered in coordinated universal time (UTC). For example, a Time of Day value of 10:00 a.m., 2 January, means a start time of 10:00 a.m. eastern standard time (UTC-3:00) for routes beginning in the eastern time zone and 10:00 a.m. central standard time (UTC-4:00) for routes beginning in the central time zone. The start times are offset by one hour in UTC. The arrive and depart times and dates recorded in the output Stops feature class will refer to the local time zone of the first stop for each route.
  • UTC—The Time of Day parameter refers to UTC. Choose this option if you want to generate a route for a specific time, such as now, but aren't certain in which time zone the first stop will be located. If you are generating many routes spanning multiple time zones, the start times in UTC are simultaneous. For example, a Time of Day value of 10:00 a.m., 2 January, means a start time of 5:00 a.m. eastern standard time (UTC-5:00) for routes beginning in the eastern time zone and 4:00 a.m. central standard time (UTC-6:00) for routes beginning in the central time zone. Both routes start at 10:00 a.m. UTC. The arrive and depart times and dates recorded in the output Stops feature class will refer to UTC.
String
UTurn_at_Junctions
(Optional)

Specifies the U-turn policy at junctions. Allowing U-turns implies the solver can turn around at a junction and double back on the same street. Given that junctions represent street intersections and dead ends, different vehicles may be able to turn around at some junctions but not at others—it depends on whether the junction represents an intersection or dead end. To accommodate this, the U-turn policy parameter is implicitly specified by the number of edges that connect to the junction, which is known as junction valency. The acceptable values for this parameter are listed below; each is followed by a description of its meaning in terms of junction valency.

  • Allowed—U-turns are permitted at junctions with any number of connected edges. This is the default value.
  • Not Allowed—U-turns are prohibited at all junctions, regardless of junction valency. However, U-turns are still permitted at network locations even when this option is chosen, but you can set the individual network locations' CurbApproach attribute to prohibit U-turns there as well.
  • Allowed Only at Dead Ends—U-turns are prohibited at all junctions except those that have only one adjacent edge (a dead end).
  • Allowed Only at Intersections and Dead Ends—U-turns are prohibited at junctions where exactly two adjacent edges meet but are permitted at intersections (junctions with three or more adjacent edges) and dead ends (junctions with exactly one adjacent edge). Often, networks have extraneous junctions in the middle of road segments. This option prevents vehicles from making U-turns at these locations.

This parameter is ignored unless Travel Mode is set to Custom.

String
Point_Barriers
(Optional)

Use this parameter to specify one or more points that will act as temporary restrictions or represent additional time or distance that may be required to travel on the underlying streets. For example, a point barrier can be used to represent a fallen tree along a street or a time delay spent at a railroad crossing.

The tool imposes a limit of 250 points that can be added as barriers.

When specifying point barriers, you can set properties for each, such as its name or barrier type, using the following attributes:

Name

The name of the barrier.

BarrierType

Specifies whether the point barrier restricts travel completely or adds time or distance when it is crossed. The value for this attribute is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Restriction)—Prohibits travel through the barrier. The barrier is referred to as a restriction point barrier since it acts as a restriction.

  • 2 (Added Cost)—Traveling through the barrier increases the travel time or distance by the amount specified in the Additional_Time, Additional_Distance, or AdditionalCost field. This barrier type is referred to as an added cost point barrier.

Additional_Time

The added travel time when the barrier is traversed. This field is applicable only for added-cost barriers and when the Measurement Units parameter value is time based.

This field value must be greater than or equal to zero, and its units must be the same as those specified in the Measurement Units parameter.

Additional_Distance

The added distance when the barrier is traversed. This field is applicable only for added-cost barriers and when the Measurement Units parameter value is distance based.

The field value must be greater than or equal to zero, and its units must be the same as those specified in the Measurement Units parameter.

AdditionalCost

The added cost when the barrier is traversed. This field is applicable only for added-cost barriers when the Measurement Units parameter value is neither time based nor distance based.

FullEdge

Specifies how the restriction point barriers are applied to the edge elements during the analysis. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (False)—Permits travel on the edge up to the barrier but not through it. This is the default value.
  • 1 (True)—Restricts travel anywhere on the associated edge.

CurbApproach

Specifies the direction of traffic that is affected by the barrier. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Either side of vehicle)—The barrier affects travel over the edge in both directions.
  • 1 (Right side of vehicle)—Vehicles are only affected if the barrier is on their right side during the approach. Vehicles that traverse the same edge but approach the barrier on their left side are not affected by the barrier.
  • 2 (Left side of vehicle)—Vehicles are only affected if the barrier is on their left side during the approach. Vehicles that traverse the same edge but approach the barrier on their right side are not affected by the barrier.

Because junctions are points and don't have a side, barriers on junctions affect all vehicles regardless of the curb approach.

The CurbApproach attribute works with both types of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider a facility on the left side of a vehicle. It is always on the left side regardless of whether the vehicle travels on the left or right half of the road. What may change with national driving standards is your decision to approach a facility from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, to arrive at a facility and not have a lane of traffic between the vehicle and the facility, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

Bearing

The direction in which a point is moving. The units are degrees and are measured clockwise from true north. This field is used in conjunction with the BearingTol field.

Bearing data is usually sent automatically from a mobile device equipped with a GPS receiver. Try to include bearing data if you are loading an input location that is moving, such as a pedestrian or a vehicle.

Using this field tends to prevent adding locations to the wrong edges, which can occur when a vehicle is near an intersection or an overpass, for example. Bearing also helps the tool determine on which side of the street the point is.

BearingTol

The bearing tolerance value creates a range of acceptable bearing values when locating moving points on an edge using the Bearing field. If the Bearing field value is within the range of acceptable values that are generated from the bearing tolerance on an edge, the point can be added as a network location there; otherwise, the closest point on the next-nearest edge is evaluated.

The units are in degrees, and the default value is 30. Values must be greater than 0 and less than 180. A value of 30 means that when Network Analyst attempts to add a network location on an edge, a range of acceptable bearing values is generated 15 degrees to either side of the edge (left and right) and in both digitized directions of the edge.

NavLatency

This field is only used in the solve process if the Bearing and BearingTol fields also have values; however, entering a NavLatency field value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much cost is expected to elapse from the moment GPS information is sent from a moving vehicle to a server and the moment the processed route is received by the vehicle's navigation device.

The units of NavLatency are the same as the units of the impedance attribute.

Feature Set
Line_Barriers
(Optional)

Use this parameter to specify one or more lines that prohibit travel anywhere the lines intersect the streets. For example, a parade or protest that blocks traffic across several street segments can be modeled with a line barrier. A line barrier can also quickly fence off several roads from being traversed, thereby channeling possible routes away from undesirable parts of the street network.

The tool imposes a limit on the number of streets you can restrict using the Line Barriers parameter. While there is no limit to the number of lines you can specify as line barriers, the combined number of streets intersected by all the lines cannot exceed 500.

When specifying the line barriers, you can set name and barrier type properties for each using the following attributes:

Name

The name of the barrier.

Feature Set
Polygon_Barriers
(Optional)

Use this parameter to specify polygons that either completely restrict travel or proportionately scale the time or distance required to travel on the streets intersected by the polygons.

The service imposes a limit on the number of streets you can restrict using the Polygon Barriers parameter. While there is no limit to the number of polygons you can specify as polygon barriers, the combined number of streets intersected by all the polygons cannot exceed 2,000.

When specifying the polygon barriers, you can set properties for each, such as its name or barrier type, using the following attributes:

Name

The name of the barrier.

BarrierType

Specifies whether the barrier restricts travel completely or scales the cost (such as time or distance) for traveling through it. The field value is specified as one of the following integers (use the numeric code, not the name in parentheses):

  • 0 (Restriction)—Prohibits traveling through any part of the barrier. The barrier is referred to as a restriction polygon barrier since it prohibits traveling on streets intersected by the barrier. One use of this type of barrier is to model floods covering areas of the street that make traveling on those streets impossible.

  • 1 (Scaled Cost)—Scales the cost (such as travel time or distance) required to travel the underlying streets by a factor specified using the ScaledTimeFactor or ScaledDistanceFactor field. If the streets are partially covered by the barrier, the travel time or distance is apportioned and then scaled. For example, a factor of 0.25 means that travel on underlying streets is expected to be four times faster than normal. A factor of 3.0 means it is expected to take three times longer than normal to travel on underlying streets. This barrier type is referred to as a scaled-cost polygon barrier. It can be used to model storms that reduce travel speeds in specific regions, for example.

ScaledTimeFactor

This is the factor by which the travel time of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

This field is applicable only for scaled-cost barriers and when the Measurement Units parameter is time-based.

ScaledDistanceFactor

This is the factor by which the distance of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

This field is applicable only for scaled-cost barriers and when the Measurement Units parameter is distance-based.

ScaledCostFactor

This is the factor by which the cost of the streets intersected by the barrier is multiplied. The field value must be greater than zero.

This field is applicable only for scaled-cost barriers when the Measurement Units parameter is neither time-based nor distance-based.

Feature Set
Use_Hierarchy
(Optional)

Specifies whether hierarchy will be used when finding the shortest paths between stops.

  • Checked (True in Python)—Hierarchy will be used when finding routes. When hierarchy is used, the tool identifies higher-order streets (such as freeways) before lower-order streets (such as local roads) and can be used to simulate the driver preference of traveling on freeways instead of local roads even if that means a longer trip. This is especially useful when finding routes to faraway locations, because drivers on long-distance trips tend to prefer traveling on freeways, where stops, intersections, and turns can be avoided. Using hierarchy is computationally faster, especially for long-distance routes, as the tool identifies the best route from a relatively smaller subset of streets.
  • Unchecked (False in Python)—Hierarchy will not be used when finding routes. If hierarchy is not used, the tool considers all the streets and doesn't necessarily identify higher-order streets when finding the route. This is often used when finding short routes in a city.

The tool automatically reverts to using hierarchy if the straight-line distance between facilities and demand points is greater than 50 miles (80.46 kilometers), even if this parameter is unchecked (set to False in Python).

This parameter is ignored unless Travel Mode is set to Custom. When modeling a custom walking mode, it is recommended that you turn off hierarchy since hierarchy is designed for motorized vehicles.

Boolean
Restrictions
[Restrictions,...]
(Optional)

The restrictions that will be honored by the tool when finding the best routes.

A restriction represents a driving preference or requirement. In most cases, restrictions cause roads to be prohibited. For instance, using the Avoid Toll Roads restriction will result in a route that will include toll roads only when it is required to travel on toll roads to visit an incident or a facility. Height Restriction makes it possible to route around any clearances that are lower than the height of the vehicle. If you are carrying corrosive materials on the vehicle, using the Any Hazmat Prohibited restriction prevents hauling the materials along roads where it is marked illegal to do so.

Note:

The values you provide for this parameter are ignored unless Travel Mode is set to Custom.

Note:

Some restrictions require an additional value to be specified for their use. This value must be associated with the restriction name and a specific parameter intended to work with the restriction. You can identify such restrictions if their names appear in the AttributeName column of the Attribute Parameter Values parameter. Specify the ParameterValue field for the Attribute Parameter Values parameter for the restriction to be correctly used when finding traversable roads.

Note:

Some restrictions are supported only in certain countries; their availability is stated by region in the list below. Of the restrictions that have limited availability within a region, you can determine whether the restriction is available in a particular country by reviewing the table in the Country list section of Network analysis coverage. If a country has a value of Yes in the Logistics Attribute column, the restriction with select availability in the region is supported in that country. If you specify restriction names that are not available in the country where the incidents are located, the service ignores the invalid restrictions. The service also ignores restrictions when the Restriction Usage attribute parameter value is between 0 and 1 (see the Attribute Parameter Value parameter). It prohibits all restrictions when the Restriction Usage parameter value is greater than 0.

The service supports the following restrictions:

  • Any Hazmat Prohibited—The results will not include roads where transporting any kind of hazardous material is prohibited. Availability: Select countries in North America and Europe

String
Attribute_Parameter_Values
(Optional)

Use this parameter to specify additional values required by an attribute or restriction, such as to specify whether the restriction prohibits, avoids, or prefers travel on restricted roads. If the restriction is meant to avoid or prefer roads, you can further specify the degree to which they are avoided or preferred using this parameter. For example, you can choose to never use toll roads, avoid them as much as possible, or prefer them.

Note:

The values you provide for this parameter are ignored unless Travel Mode is set to Custom.

If you specify the Attribute Parameter Values parameter from a feature class, the field names on the feature class must match the fields as follows:

  • AttributeName—The name of the restriction.
  • ParameterName—The name of the parameter associated with the restriction. A restriction can have one or more ParameterName field values based on its intended use.
  • ParameterValue—The value for ParameterName used by the tool when evaluating the restriction.

The Attribute Parameter Values parameter is dependent on the Restrictions parameter. The ParameterValue field is applicable only if the restriction name is specified as the value for the Restrictions parameter.

In Attribute Parameter Values, each restriction (listed as AttributeName) has a ParameterName field value, Restriction Usage, that specifies whether the restriction prohibits, avoids, or prefers travel on the roads associated with the restriction as well as the degree to which the roads are avoided or preferred. The Restriction Usage ParameterName can be assigned any of the following string values or their equivalent numeric values listed in the parentheses:

  • PROHIBITED (-1)—Travel on the roads using the restriction is completely prohibited.
  • AVOID_HIGH (5)—It is highly unlikely the tool will include in the route the roads that are associated with the restriction.
  • AVOID_MEDIUM (2)—It is unlikely the tool will include in the route the roads that are associated with the restriction.
  • AVOID_LOW (1.3)—It is somewhat unlikely the tool will include in the route the roads that are associated with the restriction.
  • PREFER_LOW (0.8)—It is somewhat likely the tool will include in the route the roads that are associated with the restriction.
  • PREFER_MEDIUM (0.5)—It is likely the tool will include in the route the roads that are associated with the restriction.
  • PREFER_HIGH (0.2)—It is highly likely the tool will include in the route the roads that are associated with the restriction.

In most cases, you can use the default value, PROHIBITED, as the Restriction Usage value if the restriction is dependent on a vehicle characteristic such as vehicle height. However, in some cases, the Restriction Usage value depends on your routing preferences. For example, the Avoid Toll Roads restriction has the default value of AVOID_MEDIUM for the Restriction Usage attribute. This means that when the restriction is used, the tool will route around toll roads when it can. AVOID_MEDIUM also indicates how important it is to avoid toll roads when finding the best route; it has a medium priority. Choosing AVOID_LOW puts lower importance on avoiding tolls; choosing AVOID_HIGH instead gives it a higher importance and makes it more acceptable for the service to generate longer routes to avoid tolls. Choosing PROHIBITED entirely disallows travel on toll roads, making it impossible for a route to travel on any portion of a toll road. Keep in mind that avoiding or prohibiting toll roads, and avoiding toll payments, is the objective for some. In contrast, others prefer to drive on toll roads, because avoiding traffic is more valuable to them than the money spent on tolls. In the latter case, choose PREFER_LOW, PREFER_MEDIUM, or PREFER_HIGH as the value for Restriction Usage. The higher the preference, the farther the tool will go to travel on the roads associated with the restriction.

Record Set
Route_Shape
(Optional)

Specifies the type of route features that will be output by the tool.

  • True Shape—The exact shape of the resulting route that is based on the underlying streets will be returned.
  • True Shape with Measures—The exact shape of the resulting route that is based on the underlying streets will be returned. Additionally, construct measures so the shape can be used in linear referencing. The measurements increase from the first stop and record the cumulative travel time or travel distance in the units specified by the Measurement Units parameter.
  • Straight Line—A straight line between two stops will be returned.
  • None—No shapes for the routes will be returned. This value can be useful, and return results quickly, when you are only interested in determining the total travel time or travel distance of a route.

When the Route Shape parameter is set to True Shape or True Shape with Measures, the generalization of the route shape can be further controlled using the appropriate value for the Route Line Simplification Tolerance parameter.

No matter which value you choose for the Route Shape parameter, the best route is always determined by minimizing the travel time or the travel distance, never using the straight-line distance between stops. This means that only the route shapes are different, not the underlying streets that are searched when finding the route.

String
Route_Line_Simplification_Tolerance
(Optional)

The amount by which the geometry of the output lines will be simplified for routes, directions, and route edges.

The tool ignores this parameter if the Route Shape parameter isn't set to True Shape.

Simplification maintains critical points on a route, such as turns at intersections, to define the essential shape of the route and removes other points. The simplification distance you specify is the maximum allowable offset that the simplified line can deviate from the original line. Simplifying a line reduces the number of vertices that are part of the route geometry. This improves the tool processing time.

Linear Unit
Populate_Route_Edges
(Optional)

Specifies whether edges for each route will be generated. Route edges represent the individual street features or other similar features that are traversed by a route. The output Route Edges layer is commonly used to determine which streets or paths are traveled on the most or least by the resultant routes.

  • Checked (True)—Route edges will be generated, and the output Route Edges layer will be populated with line features.
  • Unchecked (False)—Route edges will not be generated, and an empty output Route Edges layer will be returned.
Boolean
Populate_Directions
(Optional)

Specifies whether the tool will generate driving directions for each route.

  • Checked (True in Python)—Directions will be generated and configured based on the values of the Directions Language, Directions Style Name, and Directions Distance Units parameters.
  • Unchecked (False in Python)—Directions will not be generated, and the tool will return an empty Directions layer.

Boolean
Directions_Language
(Optional)

The language that will be used when generating travel directions.

This parameter is used only when the Populate Directions parameter is checked (True in Python).

The parameter value can be specified using one of the following two- or five-character language codes:

  • ar—Arabic
  • bg—Bulgarian
  • bs—Bosnian
  • ca—Catalan
  • cs—Czech
  • da—Danish
  • de—German
  • el—Greek
  • en—English
  • es—Spanish
  • et—Estonian
  • fi—Finnish
  • fr—French
  • he—Hebrew
  • hr—Croatian
  • hu—Hungarian
  • id—Indonesian
  • it—Italian
  • ja—Japanese
  • ko—Korean
  • lt—Lithuanian
  • lv—Latvian
  • nb—Norwegian
  • nl—Dutch
  • pl—Polish
  • pt-BR—Portuguese (Brazil)
  • pt-PT—Portuguese (Portugal)
  • ro—Romanian
  • ru—Russian
  • sk—Slovak
  • sl—Slovenian
  • sr—Serbian
  • sv—Swedish
  • th—Thai
  • tr—Turkish
  • uk—Ukrainian
  • vi—Vietnamese
  • zh-CN—Chinese (China)
  • zh-HK—Chinese (Hong Kong)
  • zh-TW—Chinese (Taiwan)

The tool first searches for an exact match for the specified language including any language localization. If an exact match is not found, it tries to match the language family. If a match is still not found, the tool returns the directions using the default language, English. For example, if the directions language is specified as es-MX (Mexican Spanish), the tool will return the directions in Spanish, as it supports the es language code but not es-MX.

Caution:

If a language supports localization, such as Brazilian Portuguese (pt-BR) and European Portuguese (pt-PT), specify the language family and the localization. If you only specify the language family, the tool will not match the language family and instead return directions in the default language, English. For example, if the directions language specified is pt, the tool will return the directions in English since it cannot determine whether the directions should be returned in pt-BR or pt-PT.

String
Directions_Distance_Units
(Optional)

Specifies the units that will display travel distance in the driving directions. This parameter is used only when the Populate Directions parameter is checked (True in Python).

  • Miles—The linear unit will be miles.
  • Kilometers—The linear unit will be kilometers.
  • Meters—The linear unit will be meters.
  • Feet—The linear unit will be feet.
  • Yards—The linear unit will be yards.
  • NauticalMiles—The linear unit will be nautical miles.
String
Directions_Style_Name
(Optional)

Specifies the name of the formatting style for the directions. This parameter is used only when the Populate Directions parameter is checked (True in Python).

  • NA Desktop—The style will be turn-by-turn directions suitable for printing.
  • NA Navigation—The style will be turn-by-turn directions designed for an in-vehicle navigation device.
String
Travel_Mode
(Optional)

The mode of transportation that will be modeled in the analysis. Travel modes are managed in ArcGIS Online and can be configured by the administrator of your organization to reflect the organization's workflows. Specify the name of a travel mode that is supported by your organization.

To get a list of supported travel mode names, run the Get Travel Modes tool from the Utilities toolbox under the same GIS Server connection you used to access the tool. The Get Travel Modes tool adds a table, Supported Travel Modes, to the application. Any value in the Travel Mode Name field from the Supported Travel Modes table can be specified as input. You can also specify the value from the Travel Mode Settings field as input. This speeds up tool execution, as the tool does not have to find the settings based on the travel mode name.

The default value, Custom, allows you to configure a custom travel mode using the custom travel mode parameters (UTurn at Junctions, Use Hierarchy, Restrictions, Attribute Parameter Values, and Impedance). The default values of the custom travel mode parameters model traveling by car. You can also choose Custom and set the custom travel mode parameters listed above to model a pedestrian with a fast walking speed or a truck with a given height, weight, and cargo of certain hazardous materials. You can try different settings to get the analysis results you want. Once you have identified the analysis settings, work with your organization's administrator and save these settings as part of a new or existing travel mode so that everyone in your organization can run the analysis with the same settings.

Caution:

When you choose Custom, the values you set for the custom travel mode parameters are included in the analysis. Specifying another travel mode, as defined by your organization, causes any values you set for the custom travel mode parameters to be ignored; the tool overrides them with values from the specified travel mode.

String
Impedance
(Optional)

Specifies the impedance, which is a value that represents the effort or cost of traveling along road segments or on other parts of the transportation network.

Travel time is an impedance: a car may take 1 minute to travel a mile along an empty road. Travel times can vary by travel mode—a pedestrian may take more than 20 minutes to walk the same mile, so it is important to choose the right impedance for the travel mode you are modeling.

Travel distance can also be an impedance; the length of a road in kilometers can be thought of as impedance. Travel distance in this sense is the same for all modes—a kilometer for a pedestrian is also a kilometer for a car. (What may change is the pathways on which the different modes are allowed to travel, which affects distance between points, and this is modeled by travel mode settings.)

Caution:

The value you provide for this parameter is ignored unless Travel Mode is set to Custom, which is the default value.

Choose from the following impedance values:

  • TravelTime—Historical and live traffic data is used. This option is good for modeling the time it takes automobiles to travel along roads at a specific time of day using live traffic speed data where available. When using TravelTime, you can optionally set the TravelTime::Vehicle Maximum Speed (km/h) attribute parameter to specify the physical limitation of the speed the vehicle is capable of traveling.
  • Minutes—Live traffic data is not used, but historical average speeds for automobiles data is used.
  • TruckTravelTime—Historical and live traffic data is used, but the speed is capped at the posted truck speed limit. This is good for modeling the time it takes for the trucks to travel along roads at a specific time. When using TruckTravelTime, you can optionally set the TruckTravelTime::Vehicle Maximum Speed (km/h) attribute parameter to specify the physical limitation of the speed the truck is capable of traveling.
  • TruckMinutes—Live traffic data is not used, but the smaller of the historical average speeds for automobiles and the posted speed limits for trucks is used.
  • WalkTime—The default is a speed of 5 km/hr on all roads and paths, but this can be configured through the WalkTime::Walking Speed (km/h) attribute parameter.
  • Miles—Length measurements along roads are stored in miles and can be used for performing analysis based on shortest distance.
  • Kilometers—Length measurements along roads are stored in kilometers and can be used for performing analysis based on shortest distance.
  • TimeAt1KPH—The default is a speed of 1 km/hr on all roads and paths. The speed cannot be changed using any attribute parameter.
  • Drive Time—Travel times for a car are modeled. These travel times are dynamic and fluctuate according to traffic flows in areas where traffic data is available. This is the default value.
  • Truck Time—Travel times for a truck are modeled. These travel times are static for each road and don't fluctuate with traffic.
  • Walk Time—Travel times for a pedestrian are modeled.
  • Travel Distance—Length measurements along roads and paths are stored. To model walk distance, choose this option and ensure that Walking is set for the Restriction parameter. Similarly, to model drive or truck distance, choose Travel Distance here and set the appropriate restrictions so the vehicle travels only on roads where it is permitted to do so.

If you choose a time-based impedance, such as TravelTime, TruckTravelTime, Minutes, TruckMinutes, or WalkTime, the Measurement Units parameter must be set to a time-based value. If you choose a distance-based impedance, such as Miles or Kilometers, Measurement Units must be distance based.

Legacy:

Drive Time, Truck Time, Walk Time, and Travel Distance impedance values are no longer supported and will be removed in a future release. If you use one of these values, the tool uses the value of the Time Impedance parameter for time-based values and the Distance Impedance parameter for distance-based values.

String
Time_Zone_for_Time_Windows
(Optional)

Specifies the time zone that will be used for the time window values on stops. The time windows are specified as part of TimeWindowStart and TimeWindowEnd fields on stops. This parameter is applicable only when the Use Time Windows parameter is checked (set to True).

  • Geographically Local—The time window values associated with the stops are in the time zone in which the stops are located. For example, if the stop is located in an area that follows eastern standard time and has time window values of 8 AM and 10 AM, the time window values will be treated as 8 a.m. and 10 a.m eastern standard time. This is the default.
  • UTC—The time window values associated with the stops are in coordinated universal time (UTC). For example, if the stop is located in an area that follows eastern standard time and has time window values of 8 AM and 10 AM, the time window values will be treated as 12 p.m and 2 p.m eastern standard time, assuming eastern standard time is obeying daylight saving time. Specifying the time window values in UTC is useful if you do not know the time zone in which the stops are located or if you have stops in multiple time zones and you want all the time windows to start simultaneously.
String
Save_Output_Network_Analysis_Layer
(Optional)

Specifies whether the analysis settings will be saved as a network analysis layer file. You cannot directly work with this file even when you open the file in an ArcGIS Desktop application such as ArcMap. It is meant to be sent to Esri Technical Support to diagnose the quality of results returned from the tool.

  • Checked (True in Python)—The output will be saved as a network analysis layer file. The file will be downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the value for the Output Network Analysis Layer parameter in the entry corresponding to the tool service in the geoprocessing history of the project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu of the Output Network Analysis Layer parameter in the entry corresponding to the tool service in the Geoprocessing Results window.
  • Unchecked (False in Python)—The output will not be saved as a network analysis layer file. This is the default.

Boolean
Overrides
(Optional)

Note:

This parameter is for internal use only.

String
Save_Route_Data
(Optional)

Specifies whether the output will include a .zip file that contains a file geodatabase with the inputs and outputs of the analysis in a format that can be used to share route layers with ArcGIS Online or Portal for ArcGIS.

  • Checked (True in Python)—The route data will be saved as a .zip file. The file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the value for the Output Route Data parameter in the entry corresponding to the tool operation in the geoprocessing history of the project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu of the Output Route Data parameter in the entry corresponding to the tool operation in the Geoprocessing Results window.
  • Unchecked (False in Python)—The route data will not be saved as a .zip file. This is the default.

Boolean
Time_Impedance
(Optional)

The time-based impedance value represents the travel time along road segments or on other parts of the transportation network.

Note:
If the impedance for the travel mode, as specified using the Impedance parameter, is time based, the values for the Time Impedance and Impedance parameters must be identical. Otherwise, the service will return an error.
  • Minutes—Time impedance will be minutes.
  • TravelTime—Time impedance will be travel time.
  • TimeAt1KPH—Time impedance will be time at one kilometer per hour.
  • WalkTime—Time impedance will be walk time.
  • TruckMinutes—Time impedance will be truck minutes.
  • TruckTravelTime—Time impedance will be truck travel time.
String
Distance_Impedance
(Optional)

The distance-based impedance value represents the travel distance along road segments or on other parts of the transportation network.

Note:
If the impedance for the travel mode, as specified using the Impedance parameter, is distance based, the values for the Distance Impedance and Impedance parameters must be identical. Otherwise, the service will return an error.
  • Miles—Distance impedance will be miles.
  • Kilometers—Distance impedance will be kilometers.
String
Output_Format
(Optional)

Specifies the format in which the output features will be returned.

  • Feature Set—The output features will be returned as feature classes and tables. This is the default.
  • JSON File—The output features will be returned as a compressed file containing the JSON representation of the outputs. When this option is specified, the output is a single file (with a .zip extension) that contains one or more JSON files (with a .json extension) for each of the outputs created by the service.
  • GeoJSON File—The output features will be returned as a compressed file containing the GeoJSON representation of the outputs. When this option is specified, the output is a single file (with a .zip extension) that contains one or more GeoJSON files (with a .geojson extension) for each of the outputs created by the service.

When a file-based output format, such as JSON File or GeoJSON File, is specified, no outputs will be added to the display because the application, such as ArcMap or ArcGIS Pro, cannot draw the contents of the result file. Instead, the result file is downloaded to a temporary directory on your machine. In ArcGIS Pro, the location of the downloaded file can be determined by viewing the value for the Output Result File parameter in the entry corresponding to the tool operation in the geoprocessing history of the project. In ArcMap, the location of the file can be determined by accessing the Copy Location option in the shortcut menu of the Output Result File parameter in the entry corresponding to the tool operation in the Geoprocessing Results window.

String
Ignore_Invalid_Locations
(Optional)

Specifies whether invalid input locations will be ignored.

  • SKIP—Network locations that are unlocated will be ignored and the analysis will run using valid network locations only. The analysis will also continue if locations are on nontraversable elements or have other errors. This is useful if you know the network locations are not all correct, but you want to run the analysis with the network locations that are valid. This is the default.
  • HALT—Invalid locations will not be ignored. Do not run the analysis if there are invalid locations. Correct the invalid locations and rerun the analysis.
Boolean
Locate_Settings
(Optional)

Use this parameter to specify settings that affect how inputs are located, such as the maximum search distance to use when locating the inputs on the network or the network sources being used for locating.

Learn more about locating inputs

The locator JSON object has the following properties:

  • tolerance and toleranceUnits—Allows you to control the maximum search distance when locating inputs. If no valid network location is found within this distance, the input features will be considered unlocated. A small search tolerance decreases the likelihood of locating on the wrong street but increases the likelihood of not finding any valid network location. The toleranceUnits parameter value can be specified as one of the following values:
    • esriCentimeters
    • esriDecimalDegrees
    • esriDecimeters
    • esriFeet
    • esriInches
    • esriIntFeet
    • esriIntInches
    • esriIntMiles
    • esriIntNauticalMiles
    • esriIntYards
    • esriKilometers
    • esriMeters
    • esriMiles
    • esriMillimeters
    • esriNauticalMiles
    • esriYards
  • sources— Allows you to control which network source can be used for locating. For example, you can configure the analysis to locate inputs on streets but not on sidewalks. The list of possible sources on which to locate is specific to the network dataset this service references. Only the sources that are present in the sources array are used for locating. Sources is specified as an array of objects each having the following property:
    • name—The name of the network source feature class that can be used for locating inputs
  • allowAutoRelocate—Allows you to control whether inputs with existing network location fields can be automatically relocated when solving to ensure valid, routable location fields for the analysis. If the value is true, points located on restricted network elements and points affected by barriers will be relocated to the closest routable location. If the value is false, network location fields will be used as is even if the points are unreachable, and this may cause the solve to fail. Even if the value is false, inputs with no location fields or incomplete location fields will be located during the solve operation.
Note:
Currently, you can't specify different source names for the sources array. Also, allowAutoRelocate is always set to true since the service does not support location fields.

The parameter value is specified as a JSON object. The JSON object allows you to specify a locator JSON for all input feature in the analysis, or you can specify an override for a particular input. The override allows you to have different settings for each analysis input. For example, you can disallow stops to locate on highway ramps and allow point barriers to locate on highway ramps. When specifying the Locate_Settings JSON, you must provide the tolerance, toleranceUnits, and allowAutoRelocate properties. If you need to provide a different locator JSON for a particular input class, you must include the overrides property for that input. The property name must match the input parameter name. The locator JSON for a particular input doesn't need to include all the properties; you only need to include the properties that are different from the default locator JSON properties.
