Summary

Creates an origin-destination (OD) cost matrix from multiple origins to multiple destinations. An OD cost matrix is a table that contains the travel time and travel distance from each origin to each destination. Additionally, it ranks the destinations that each origin connects to in ascending order based on the minimum time or distance required to travel from that origin to each destination. The best path on the street network is discovered for each origin-destination pair, and the travel times and travel distances are stored as attributes of the output lines. Even though the lines are straight for performance reasons, they store the travel time and travel distance along the street network, not straight-line distance.

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.

An origin-destination cost matrix solution

Usage

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

  • The tool finds the closest facilities based on travel time if the value for the Measurement Units parameter is time based. Similarly, the tool uses travel distance if the measurement units are distance based.

  • You must specify at least one origin and one destination to successfully run the tool. You can load up to 1000 origins and 1000 destinations.

  • You can add 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 choose to use the road hierarchy when solving so results are generated quicker than exact routes, but the solution may be somewhat 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 origin-destination pair cannot be greater than 50 miles (80.46 kilometers) when the travel mode is of type 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
Origins

Specifies the starting points from which to travel to the destinations.

You can add up to 1000 origins.

When specifying the origins, you can set properties for each—such as its name or the number of destinations to find from the origin— using the following attributes:

Name

The name of the origin. The name can be a unique identifier for the origin. The name is included in the output lines (as the OriginName field) and in the output origins (as the Name field) and can be used to join additional information from the tool outputs to the attributes of your origins.

If the name is not specified, a unique name prefixed with Location is automatically generated.

TargetDestinationCount

The maximum number of destinations to find for the origin.

If a value is not specified, the value from the Number of Destinations to Find parameter is used.

This field allows you to specify a different number of destinations to find for each origin. For example, using this field, you can find the three closest destinations from one origin and the two closest destinations from another origin.

Cutoff

The impedance value at which to stop searching for destinations from a given origin. This attribute allows you to specify a different cutoff value for each destination. For example, using this attribute, you can specify to search for destinations within five minutes of travel time from one origin and to search for destinations within eight minutes of travel time from another origin.

The units of the cutoff are the same as the units of your impedance attribute. If a value is not specified, the value from the Cutoff parameter is used.

CurbApproach

Specifies the direction a vehicle may depart from the origin. 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 depart the origin in either direction, so a U-turn is allowed at the origin. This setting can be chosen if it is possible and practical for a vehicle to turn around at the origin. This decision may depend on the width of the road and the amount of traffic or whether the origin has a parking lot where vehicles can enter and turn around.
  • 1 (Right side of vehicle)—When the vehicle departs the origin, the origin 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 depart from the bus stop on the right-hand side.
  • 2 (Left side of vehicle)—When the vehicle departs the origin, 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 depart from the bus stop on the left-hand side.
  • 3 (No U-Turn)—For this tool, this value functions the same as 0 (Either side of vehicle).

The CurbApproach attribute is designed to work with both kinds of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider an origin 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 depart the origin from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, if you want to depart from an origin and not have a lane of traffic between the vehicle and the origin, 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
Destinations

Specifies the ending point locations to travel to from the origins.

You can add up to 1000 destinations.

When specifying the destinations, you can set properties for each—such as its name—using the following attributes:

Name

The name of the destination. The name can be a unique identifier for the destination. The name is included in the output lines (as the DestinationName field) and in the output destinations (as the Name field) and can be used to join additional information from the tool outputs to the attributes of your destinations.

If the name is not specified, a unique name prefixed with Location is automatically generated.

CurbApproach

Specifies the direction a vehicle may arrive at a destination. 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 arrive at the destination in either direction, so a U-turn is allowed at the origin. This setting can be chosen if it is possible and practical for a vehicle to turn around at the destination. This decision may depend on the width of the road and the amount of traffic or whether the destination has a parking lot where vehicles can enter and turn around.
  • 1 ( Right side of vehicle)—When the vehicle arrive at the destination, the destination 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 depart from the bus stop on the right-hand side.
  • 2 (Left side of vehicle)—When the vehicle arrives at the destination, 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 depart from the bus stop on the left-hand side.
  • 3 (No U-Turn)—For this tool, this value functions the same as 0 (Either side of vehicle).

The CurbApproach attribute is designed to work with both kinds of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider an origin 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 depart the origin from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, if you want to depart from an origin and not have a lane of traffic between the vehicle and the origin, 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
Travel Mode
(Optional)

The mode of transportation to model 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
Time Units
(Optional)

Specifies the units that will be used to measure and report the total travel time between each origin-destination pair.

  • Seconds—The time unit is seconds.
  • Minutes—The time unit is minutes.
  • Hours—The time unit is hours.
  • Days—The time unit is days.
String
Distance Units
(Optional)

Specifies the units that will be used to measure and report the total travel distance between each origin-destination pair.

  • Meters—The linear unit is meters.
  • Kilometers—The linear unit is kilometers.
  • Feet—The linear unit is feet.
  • Yards—The linear unit is yards.
  • Miles—The linear unit is miles.
  • Nautical Miles—The linear unit is nautical miles.
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
Number of Destinations to Find
(Optional)

The maximum number of destinations to find per origin. If a value for this parameter is not specified, the output matrix includes travel costs from each origin to every destination. Individual origins can have their own values (specified as the TargetDestinationCount field) that override the Number of Destinations to Find parameter value.

Long
Cutoff
(Optional)

The travel time or travel distance value at which to stop searching for destinations from a given origin. Any destination beyond the cutoff value will not be considered. Individual origins can have their own values (specified as the Cutoff field) that override the Cutoff parameter value.

The value must be in the units specified by the Time Unitsparameter if the impedance attribute of your travel mode is time based or in the units specified by the Distance Units parameter if the impedance attribute of your travel mode is distance based. If a value is not specified, the tool will not enforce any travel time or travel distance limit when searching for destinations.

Double
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
Point Barriers

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

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

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
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
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 your 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 tool 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

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
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.)

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
Origin Destination Line Shape

The resulting lines of an OD cost matrix can be represented with either straight-line geometry or no geometry at all. In both cases, the route is always computed along the street network by minimizing the travel time or the travel distance, never using the straight-line distance between origins and destinations.

  • Straight Line—Straight lines connect origins and destinations.
  • None—Do not return any shapes for the lines that connect origins and destinations. This is useful when you have a large number of origins and destinations and are interested only in the OD cost matrix table (and not the output line shapes).
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
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.
  • CSV File—The output features will be returned as a compressed file containing a comma-separated values (CSV) representation of the outputs. When this option is specified, the output is a single file (with a .zip extension) that contains one or more CSV files (with a .csv 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 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
Origins

Specifies the starting points from which to travel to the destinations.

You can add up to 1000 origins.

When specifying the origins, you can set properties for each—such as its name or the number of destinations to find from the origin— using the following attributes:

Name

The name of the origin. The name can be a unique identifier for the origin. The name is included in the output lines (as the OriginName field) and in the output origins (as the Name field) and can be used to join additional information from the tool outputs to the attributes of your origins.

If the name is not specified, a unique name prefixed with Location is automatically generated.

TargetDestinationCount

The maximum number of destinations to find for the origin.

If a value is not specified, the value from the Number of Destinations to Find parameter is used.

This field allows you to specify a different number of destinations to find for each origin. For example, using this field, you can find the three closest destinations from one origin and the two closest destinations from another origin.

Cutoff

The impedance value at which to stop searching for destinations from a given origin. This attribute allows you to specify a different cutoff value for each destination. For example, using this attribute, you can specify to search for destinations within five minutes of travel time from one origin and to search for destinations within eight minutes of travel time from another origin.

The units of the cutoff are the same as the units of your impedance attribute. If a value is not specified, the value from the Cutoff parameter is used.

CurbApproach

Specifies the direction a vehicle may depart from the origin. 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 depart the origin in either direction, so a U-turn is allowed at the origin. This setting can be chosen if it is possible and practical for a vehicle to turn around at the origin. This decision may depend on the width of the road and the amount of traffic or whether the origin has a parking lot where vehicles can enter and turn around.
  • 1 (Right side of vehicle)—When the vehicle departs the origin, the origin 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 depart from the bus stop on the right-hand side.
  • 2 (Left side of vehicle)—When the vehicle departs the origin, 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 depart from the bus stop on the left-hand side.
  • 3 (No U-Turn)—For this tool, this value functions the same as 0 (Either side of vehicle).

The CurbApproach attribute is designed to work with both kinds of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider an origin 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 depart the origin from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, if you want to depart from an origin and not have a lane of traffic between the vehicle and the origin, 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
Destinations

Specifies the ending point locations to travel to from the origins.

You can add up to 1000 destinations.

When specifying the destinations, you can set properties for each—such as its name—using the following attributes:

Name

The name of the destination. The name can be a unique identifier for the destination. The name is included in the output lines (as the DestinationName field) and in the output destinations (as the Name field) and can be used to join additional information from the tool outputs to the attributes of your destinations.

If the name is not specified, a unique name prefixed with Location is automatically generated.

CurbApproach

Specifies the direction a vehicle may arrive at a destination. 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 arrive at the destination in either direction, so a U-turn is allowed at the origin. This setting can be chosen if it is possible and practical for a vehicle to turn around at the destination. This decision may depend on the width of the road and the amount of traffic or whether the destination has a parking lot where vehicles can enter and turn around.
  • 1 ( Right side of vehicle)—When the vehicle arrive at the destination, the destination 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 depart from the bus stop on the right-hand side.
  • 2 (Left side of vehicle)—When the vehicle arrives at the destination, 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 depart from the bus stop on the left-hand side.
  • 3 (No U-Turn)—For this tool, this value functions the same as 0 (Either side of vehicle).

The CurbApproach attribute is designed to work with both kinds of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider an origin 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 depart the origin from one of two directions, that is, so it ends up on the right or left side of the vehicle. For example, if you want to depart from an origin and not have a lane of traffic between the vehicle and the origin, 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.

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

Feature Set
Travel_Mode
(Optional)

The mode of transportation to model 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
Time_Units
(Optional)

Specifies the units that will be used to measure and report the total travel time between each origin-destination pair.

  • Seconds—The time unit is seconds.
  • Minutes—The time unit is minutes.
  • Hours—The time unit is hours.
  • Days—The time unit is days.
String
Distance_Units
(Optional)

Specifies the units that will be used to measure and report the total travel distance between each origin-destination pair.

  • Meters—The linear unit is meters.
  • Kilometers—The linear unit is kilometers.
  • Feet—The linear unit is feet.
  • Yards—The linear unit is yards.
  • Miles—The linear unit is miles.
  • NauticalMiles—The linear unit is nautical miles.
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
Number_of_Destinations_to_Find
(Optional)

The maximum number of destinations to find per origin. If a value for this parameter is not specified, the output matrix includes travel costs from each origin to every destination. Individual origins can have their own values (specified as the TargetDestinationCount field) that override the Number of Destinations to Find parameter value.

Long
Cutoff
(Optional)

The travel time or travel distance value at which to stop searching for destinations from a given origin. Any destination beyond the cutoff value will not be considered. Individual origins can have their own values (specified as the Cutoff field) that override the Cutoff parameter value.

The value must be in the units specified by the Time Unitsparameter if the impedance attribute of your travel mode is time based or in the units specified by the Distance Units parameter if the impedance attribute of your travel mode is distance based. If a value is not specified, the tool will not enforce any travel time or travel distance limit when searching for destinations.

Double
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
Point_Barriers

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

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

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
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
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 your 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.

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
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.

  • 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
Origin_Destination_Line_Shape

The resulting lines of an OD cost matrix can be represented with either straight-line geometry or no geometry at all. In both cases, the route is always computed along the street network by minimizing the travel time or the travel distance, never using the straight-line distance between origins and destinations.

  • Straight Line—Straight lines connect origins and destinations.
  • None—Do not return any shapes for the lines that connect origins and destinations. This is useful when you have a large number of origins and destinations and are interested only in the OD cost matrix table (and not the output line shapes).
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
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.
  • CSV File—The output features will be returned as a compressed file containing a comma-separated values (CSV) representation of the outputs. When this option is specified, the output is a single file (with a .zip extension) that contains one or more CSV files (with a .csv 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 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.

String

Derived Output

NameExplanationData Type
Solve_Succeeded

Determines whether the service successfully generated the origin destination cost matrix.

Boolean
Output_Origin_Destination_Lines

This provides access to the lines connecting the origins to the destinations.

Feature Set
Output_Origins

This provides information about the origins used in the analysis such as the total number of destinations reached from a given origin, or the origins that could not be included in the analysis.

Feature Set
Output_Destinations

This provides information about the destinations used in the analysis such as the total number of origins that were reached from a given origin, or the destinations that could not be included in the analysis.

Feature Set
Output_Network_Analysis_Layer

The network analysis layer, with properties configured in the tool parameters, that can be used for further analysis or debugging in the map.

File
Output_Result_File

A .zip file containing the results of the analysis with one or more files for each output. The format of the individual files is specified by the Output Format parameter.

File
Output_Network_Analysis_Layer_Package

A layer package that includes a network analysis layer with the data and settings used in the analysis.

File
Usage_Cost

This parameter returns the credits used by the analysis.

Note:

Each analysis can generate a different number of billable objects and thus will use different number of credits. If the service fails to determine credits, the usage_cost parameter returns a value of -1 for credits.
