Route input data types

The input data types that can be specified when performing a route analysis are described below.

Stops

Specify the locations you want the output route or routes to visit.

The data type supports the following fields:

FieldDescriptionData type

Name

The name of the stop. The name is used in the driving directions. If the name is not specified, a unique name prefixed with Location is automatically generated in the output stops, routes, and directions.

String

RouteName

The name of the route to which the stop is assigned. Assigning the same route name to different stops causes those stops to be grouped together and visited by the same route. You can generate many routes in a single solve by assigning unique route names to different groups of stops.

String

Sequence

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

If the findBestSequence property is set to True, all but possibly the first and last sequence values for each route name are ignored so the tool can find the sequence that minimizes overall travel for each route. The values for the preserveFirstStop, preserveLastStop, and returnToStart properties determine whether the first or last sequence values for each route are ignored.

Integer

AdditionalTime

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

The units for this attribute value are specified by the timeUnits property of the analysis object.

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

Double

AdditionalDistance

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

The units for this attribute value are specified by the distanceUnits property of the analysis object.

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

Double

AdditionalCost

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

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

Double

TimeWindowStart

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

The value for this attribute should be a date and time value and can be specified using a datetime Python object, such as datetime.datetime(2019, 5, 11, 8, 30, 0), which represents Saturday May 11 2019 08:30:00 AM. The time zone for the value is specified by the timeZoneForTimeWindows property of the analysis object.

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

Date

TimeWindowEnd

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

The value for this attribute should be a date and time value and can be specified using a datetime Python object, such as datetime.datetime(2019, 5, 11, 17, 30, 0), which represents Saturday May 11 2019 05:30:00 PM. The time zone for the value is specified by the timeZoneForTimeWindows property of the analysis object.

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

Date

CurbApproach

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

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

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

Integer

LocationType

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

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

Integer

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.

For more information, see Bearing and BearingTol in the ArcGIS help system.

Double

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 value from the Bearing field 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 zero 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.

For more information, see Bearing and BearingTol in the ArcGIS help system.

Double

NavLatency

This field is only used in the solve process if Bearing and BearingTol also have values; however, entering a NavLatency value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much time 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 time units of NavLatency are the same as the units specified by the timeUnits property of the analysis object.

Double

Point barrier

Specify one or more points to 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 data type supports the following fields:

FieldDescriptionData type

Name

The name of the barrier.

String

BarrierType

Specifies whether the point barrier restricts travel completely or adds a cost (such as 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 cost (such as 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.

Short

Additional_Time

Indicates how much travel time is added when the barrier is traversed. This field is applicable only for added-cost barriers and only if the travel mode used for the analysis uses an impedance attribute that is time based.

This field value must be greater than or equal to zero, and the values are interpreted to be in the units specified by the timeUnits property.

Double

Additional_Distance

Indicates how much distance is added when the barrier is traversed. This field is applicable only for added-cost barriers and only if the travel mode used for the analysis uses an impedance attribute that is distance based.

This field value must be greater than or equal to zero, and the values are interpreted to be in the units specified by the distanceUnits property.

Double

AdditionalCost

Indicates how much cost is added when the barrier is traversed. This field is applicable only for added-cost barriers and only if the travel mode used for the analysis uses an impedance attribute that is neither time based nor distance based.

This field value must be greater than or equal to zero, and the values are interpreted to be in unknown units.

Double

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.

Short

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.

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

Short

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.

For more information, see Bearing and BearingTol in the ArcGIS help system.

Double

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 value from the Bearing field 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 zero and less than 180. A value of 30 means that when ArcGIS Network Analyst extension 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.

For more information, see Bearing and BearingTol in the ArcGIS help system.

Double

NavLatency

This field is only used in the solve process if Bearing and BearingTol also have values; however, entering a NavLatency value is optional, even when values are present in Bearing and BearingTol. NavLatency indicates how much time 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 time units of NavLatency are the same as the units specified by the timeUnits property of the analysis object.

Double

Line barrier

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 block several roads from being traversed, thereby channeling possible routes away from undesirable parts of the street network.

The data type supports the following fields:

FieldDescriptionData type

Name

The name of the barrier.

String

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 travel anywhere the barrier intersects your transportation network. The barrier is referred to as a restriction line barrier.
  • 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, ScaledDistanceFactor, or ScaledCostFactor 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 line barrier. It can be used to model slowdowns due to closure of traffic lanes during construction.

Short

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 only if the travel mode used for the analysis uses an impedance attribute that is time based.

Double

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 only if the travel mode used for the analysis uses an impedance attribute that is distance based.

Double

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 and only if the travel mode used for the analysis uses an impedance attribute that is neither time based nor distance based.

Double

Polygon barrier

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 data type supports the following fields:

FieldDescriptionData type

Name

The name of the barrier.

String

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, ScaledDistanceFactor, or ScaledCostFactor 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 that 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.

Short

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 only if the travel mode used for the analysis uses an impedance attribute that is time based.

Double

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 only if the travel mode used for the analysis uses an impedance attribute that is distance based.

Double

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 and only if the travel mode used for the analysis uses an impedance attribute that is neither time based nor distance based.
