  • URL:https://<gpservice-url>/GenerateOriginDestinationCostMatrix
  • Version Introduced:

Description

Use the travel cost matrix service to create an origin-destination (OD) cost matrix from multiple origins to multiple destinations. A travel cost matrix is a table that contains the cost, such as the travel time or travel distance, from every origin to every destination. It also ranks the destinations that each origin connects to in ascending order based on the minimum cost required to travel from that origin to each destination. When generating a travel cost matrix, you can specify the maximum number of destinations to find for each origin and the maximum time or distance to travel when searching for destinations.

The results from the travel cost matrix service often become input for other spatial analyses when the cost to travel on the street network is more appropriate than straight-line cost. For example, predicting the movement of people in a city is better modeled with costs based on street networks, since people tend to travel on roads and pedestrian paths.

The travel time, distance, or both for each origin-destination pair is stored in the output matrix (default) or as part of the attributes of the output lines, which can have no shapes or a straight-line shape. Even though the lines are straight, they always store the travel time and travel distance based on the street network, not based on Euclidean distance.

Tip:

The closest facility and travel cost matrix services perform similar analyses; the main difference is in the output and the computation speed. The Travel cost matrix service generates results faster but cannot return lines that follow the underlying streets or driving directions. It is designed to quickly solve large M x N problems and, as a result, does not internally contain the information required to generate route shapes and driving directions. Alternatively, the Closest facility service can return routes that follow the underlying streets and directions but is slower to run than the Travel cost matrix service. If you need driving directions or true shapes of routes, use the Closest facility service; otherwise, use the Travel cost matrix service to reduce the computation time.

Required parameters

The following parameters are required.

origins

Use this parameter to specify locations that function as starting points in generating the paths to destinations.

The origins parameter can be specified using a JSON structure that represents a set of point features. The property is optional; however, the JSON structure must specify either the url or features property:

  • url—Specify a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set.

  • features—Specify an array of features.

    Each feature in the features array represents an origin and contains the following properties:

    • geometry—Specify the input point geometry containing x and y properties along with the spatialReference property. If the spatialReference property is defined for the entire JSON, you don't need to define this property for each geometry. Doing so reduces the size of the input JSON if the input has many features and improves performance. This property is not required if the coordinates are in the default spatial reference, WGS84. If the coordinates are in a different spatial reference, you must specify the spatial reference's well-known ID (WKID). See Using spatial references to look up WKID values.
      Tip:

      It is recommended that you explicitly specify the spatialReference value, and specify it for the entire JSON rather than each individual geometry.

    • attributes—Specify each attribute as a key-value pair in which the key is the name of a given field, and the value is the attribute value for the corresponding field.

Attributes for 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

    Specify the direction a vehicle can depart from the origin.

    One of the integers listed in the Coded value column in the following table must be specified as a value of this attribute. The values in the Setting column are the descriptive names for CurbApproach attribute values that you may have seen when using the ArcGIS Network Analyst extension software.

    SettingCoded valueDescription

    Either side of vehicle

    0

    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.

    Either side of vehicle
    All arrival and departure combinations are allowed with the Either side of vehicle curb approach.

    Right side of vehicle

    1

    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 side.

    Right side of vehicle
    The allowed arrival and departure combination for the Right side of vehicle curb approach is shown.

    Left side of vehicle

    2

    When the vehicle departs the origin, the origin 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 side.

    Left side of vehicle
    The allowed arrival and departure combination for the Left side of vehicle curb approach is shown.

    No U-Turn

    3

    When the vehicle departs the origin, the origin can be on either side of the vehicle; however, when it departs, the vehicle must continue in the same direction it arrived. A U-turn is prohibited.

    No U-turns
    The allowed arrival and departure combinations for the No U-Turn curb approach are shown.

    The CurbApproach attribute is designed to work with both types of national driving standards: right-hand traffic (United States) and left-hand traffic (United Kingdom). First, consider an incident 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 an incident 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 an incident and not have a lane of traffic between the vehicle and the incident, choose 1 (Right side of vehicle) in the United States and 2 (Left side of vehicle) in the United Kingdom.

    Right side of vehicle with right-hand traffic
    With right-hand traffic, the curb approach that leaves the vehicle closest to the origin is Right side of vehicle.
    Left side of vehicle with left-hand traffic
    With left-hand traffic, the curb approach that leaves the vehicle closest to the origin is Left side of vehicle.

  • 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.

    Learn more about bearing and bearing tolerance

  • 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.

    Learn more about bearing and bearing tolerance

  • 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.

token

Use this parameter to specify a token that provides the identity of a user that has the permissions to access the service. The security and authentication page provides more information about how an access token can be obtained.

Example (replace <yourToken> with a valid token):
token=<yourToken>

f

Use this parameter to specify the response format. The parameter can have html, json or pjson as arguments, for example, f=json. The pjson value is used for printing the JSON response in a prettified format.

Optional parameters

The following parameters are optional.

travel_mode

Choose the mode of transportation for the analysis.

Travel modes are managed in ArcGIS Enterprise and can be configured by the administrator of your organization to better reflect the organization's workflows.

To learn more about travel modes, see Configure travel modes.

You must specify the JSON object containing the settings for a travel mode supported by your organization. To get a list of supported travel modes, execute the GetTravelModes tool from the Utilities service.

The value for the travel_mode parameter should be a JSON object representing travel mode settings. When you use the GetTravelModes tool from the Utilities service, you get a string representing the travel mode JSON. You need to convert this string to a valid JSON object using your API and then pass the JSON object as the value for the travel_mode parameter.

For example, below is a string representing the Walking Time travel mode as returned by the GetTravelModes tool.

"{\"attributeParameterValues\": [{\"parameterName\": \"Restriction Usage\", \"attributeName\": \"Walking\", \"value\": \"PROHIBITED\"}, {\"parameterName\": \"Restriction Usage\", \"attributeName\": \"Preferred for Pedestrians\", \"value\": \"PREFER_LOW\"}, {\"parameterName\": \"Walking Speed (km/h)\", \"attributeName\": \"WalkTime\", \"value\": 5}], \"description\": \"Follows paths and roads that allow pedestrian traffic and finds solutions that optimize travel time. The walking speed is set to 5 kilometers per hour.\", \"impedanceAttributeName\": \"WalkTime\", \"simplificationToleranceUnits\": \"esriMeters\", \"uturnAtJunctions\": \"esriNFSBAllowBacktrack\", \"restrictionAttributeNames\": [\"Preferred for Pedestrians\", \"Walking\"], \"useHierarchy\": false, \"simplificationTolerance\": 2, \"timeAttributeName\": \"WalkTime\", \"distanceAttributeName\": \"Miles\", \"type\": \"WALK\", \"id\": \"caFAgoThrvUpkFBW\", \"name\": \"Walking Time\"}"

The above value should be converted to a valid JSON object and passed as the value for the travel_mode parameter.

travel_mode={"attributeParameterValues":[{"parameterName":"Restriction Usage","attributeName":"Walking","value":"PROHIBITED"},{"parameterName":"Restriction Usage","attributeName":"Preferred for Pedestrians","value":"PREFER_LOW"},{"parameterName":"Walking Speed (km/h)","attributeName":"WalkTime","value":5}],"description":"Follows paths and roads that allow pedestrian traffic and finds solutions that optimize travel time. The walking speed is set to 5 kilometers per hour.","impedanceAttributeName":"WalkTime","simplificationToleranceUnits":"esriMeters","uturnAtJunctions":"esriNFSBAllowBacktrack","restrictionAttributeNames":["Preferred for Pedestrians","Walking"],"useHierarchy":false,"simplificationTolerance":2,"timeAttributeName":"WalkTime","distanceAttributeName":"Miles","type":"WALK","id":"caFAgoThrvUpkFBW","name":"Walking Time"}

The default value,Custom, allows you to configure your own travel mode. When you pass in Custom, you can set values for the following parameters: impedance, time_impedance, distance_impedance, uturn_at_junctions, use_hierarchy, route_line_simplification_tolerance, restrictions, and attribute_parameter_values. You can choose Custom and set the custom travel mode parameters listed above, for example, 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 out different settings to get desired analysis results. Once you have identified the analysis settings, you should work with your organization's administrator and save these settings as part of new or existing travel mode so that everyone in your organization can rerun the analysis with the same settings.

The default values of the custom travel mode parameters model traveling by car. If you specify the travel mode as Custom or do not provide a value for the travel_mode parameter, the analysis will be similar to using the default Driving Time travel mode.

Caution:

When the travel_mode parameter is not set to Custom, this means you are choosing a travel mode configured by your organization, and the service automatically overrides the values of other parameters with values that model the chosen travel mode. The following parameters are overridden: impedance, time_impedance, distance_impedance, uturn_at_junctions, use_hierarchy, route_line_simplification_tolerance, restrictions, and attribute_parameter_values.

time_units

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

The choices are as follows:

  • Seconds
  • Minutes (default)
  • Hours
  • Days

distance_units

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

The choices are as follows:

  • Meters
  • Kilometers (default)
  • Feet
  • Yards
  • Miles
  • NauticalMiles

analysis_region

This parameter is ignored by the service and specifying a value does not have any effect on the analysis.

number_of_destinations_to_find

Specify the maximum number of destinations to find per origin. If a value for this parameter is not specified (which is the default), 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.

cutoff

Specify 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_units parameter 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 (which is the default), the tool will not enforce any travel time or travel distance limit when searching for destinations.

time_of_day

Specify the time and date to depart from the origins.

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

To use traffic in the analysis, choose a time-based unit for impedance and assign a value to time_Of_day.

The time_Of_day value represents the time at which the travel begins from the input origins. The time is specified as Unix time (milliseconds since midnight, January 1, 1970).

If a time of day is not passed in, the service uses static road speeds based on average historical speeds or posted speed limits. It uses posted speeds in areas where historical traffic information isn't available.

Note:
Traffic is supported only with the driving time impedance or travel mode.

When the service is using the ArcGIS StreetMap Premium data, it can support two kinds of traffic: live and typical.

If the time_Of_day specified is within 4 hours of the current time, live traffic will be used where available. Live traffic retrieves speeds based on phone probe records, sensors, and other data sources and reflects the current travel speeds and predicts speeds for the near future. If the time_Of_day specified is earlier than 4 hours or later than 4 hours from the current time, or the road does not have live traffic, typical traffic speeds will be used. Typical speeds are based on historical traffic patterns. The travel time data is aggregated in 15 minute intervals per day of week based on multiple years worth of data. So a road may have a different travel time at Monday at 8 am, Monday at 8:15 am, or Tuesday at 8 am. Since the variance is just at the day of week and time of day, the travel time is the same on a road for any Monday at 8 am, regardless of the month or year.

If your goal is to model typical travel conditions and avoid large variances from the average due to live traffic, it is recommended to use a date from the past to ensure it doesn't coincide with the 4 hour window from the current time. As an extreme example, you can even use dates from 1990.

The Data Coverage page shows the countries Esri currently provides traffic data for.

Typical traffic

To ensure the task uses typical traffic in locations where it is available, choose a time and day of the week; then convert the day of the week to one of the following dates from 1990:

  • Monday—1/1/1990
  • Tuesday—1/2/1990
  • Wednesday—1/3/1990
  • Thursday—1/4/1990
  • Friday—1/5/1990
  • Saturday—1/6/1990
  • Sunday—1/7/1990

Set the time and date as UNIX time in milliseconds. For example, to solve for 1:03 p.m. on Thursdays, set the time and date to 1:03 p.m., January 4, 1990, and convert to milliseconds (631458180000). Although the dates representing days of the week are from 1990, typical traffic is calculated from recent traffic trends—usually over the last two years worth of data.

Live traffic

To use live traffic when and where it is available, choose a time and date and convert to Unix time.

Note:
You need to have a Live Traffic extension and configure your Street Map Premium network dataset to access live traffic.

Esri saves live traffic data for 4 hours and references predictive data extending 4 hours into the future. If the time and date you specify for this parameter is outside the 8-hour time window, or the travel time in the analysis continues past the predictive data window, the task falls back to typical traffic speeds.

Examples for time_of_day

Example one: 13:03, January 4, 1990. Typical traffic on Thursdays at 1:03 p.m.

"time_Of_day": 631458180000

Example two: 17:00, January 7, 1990. Typical traffic on Sundays at 5:00 p.m.

"time_Of_day": 631731600000

Example four: 10:20, March 18, 2015. If the current time is between 6:20 a.m., March 18, 2015, and 2:20 p.m., March 18, 2015, live traffic speeds are referenced in the analysis; otherwise, typical traffic speeds are referenced.

"time_Of_day": 1426674000000

time_zone_for_time_of_Day

Specify the time zone or zones of the time_Of_day parameter. There are two options: Geographically Local and UTC.

The default value is Geographically Local

Geographically Local

The time_Of_day value refers to the time zone or zones in which the input points are located. This option causes the analysis to have rolling start times across time zones.

Illustration of setting the value to Geographically Local—Setting time_of_day to 9:00 a.m., January 4, 1990 (631443600000 milliseconds); time_zone_for_time_Of_Day to Geographically Local; and submitting a valid request causes the drive times for points in the eastern time zone to start at 9:00 a.m. eastern Time and 9:00 a.m. central time for points in the central time zone. (The start times are offset by an hour in real or UTC time.)

Time zone for time of day parameter is set to geographically local
Input: time_Of_day is 9:00 a.m., January 4, 1990 (631443600000 milliseconds), and time_zone_for_time_Of_day is set to Geographically Local

UTC

The time_Of_day value refers to coordinated universal time (UTC). The start times for all points are simultaneous, regardless of time zones.

Illustration of setting the value to time_Of_day—Setting time_Of_day to 9:00 a.m., January 4, 1990 (631443600000 milliseconds) and the value to UTC, the start times for points in the eastern time zone is 4:00 a.m. Eastern Time and 3:00 a.m. central time for those in the central time zone.

Time zone for time of day parameter is set to UTC
Input: time_Of_day is 9:00 a.m., January 4, 1990 (631443600000 milliseconds), and time_zone_for_time_Of_day is set to UTC

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.

You can specify barrier geometries as well as attributes using a more comprehensive JSON structure that references a set of features. The property is optional; however, the JSON structure must specify either the url or features property:

  • url—Specify a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set.

  • features—Specify an array of features.

    Each feature in this array represents a point barrier and contains the following fields:

    • geometry—Specify the input point geometry containing x and y properties along with the spatialReference property. If the spatialReference property is defined for the entire JSON, you don't need to define this property for each geometry. Doing so reduces the size of the input JSON if the input has many features and improves performance. This property is not required if the coordinates are in the default spatial reference, WGS84. If the coordinates are in a different spatial reference, you must specify the spatial reference's well-known ID (WKID). See Using spatial references to look up WKID values.
      Tip:

      It is recommended that you explicitly specify the spatialReference value, and specify it for the entire JSON rather than each individual geometry.

    • attributes—Specify each attribute as a key-value pair in which the key is the name of a given field, and the value is the attribute value for the corresponding field.

Attributes for point_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.

    Two maps demonstrate how a restriction point barrier affects a route analysis.
    The first map shows the shortest path between two stops without any restriction point barriers. The second map has a road that is blocked by a fallen tree, so the shortest path between the same points is longer.

  • 2 (Added Cost)—Traveling through the barrier increases the travel time or distance by the amount specified in the Additional_[Cost] attributes. This barrier type is referred to as an added cost point barrier.

    Two maps demonstrate how added cost point barriers affect a route analysis.
    The map on the left shows the shortest path between two stops without any added cost point barrier. For the map on the right, the travel time from stop one to stop two would be the same whether going around the north end of the block or the south end; however, since crossing railroad tracks incurs a time penalty (modeled with added cost point barriers), the route with only one railroad crossing is chosen. The cost of crossing the barrier is added to the accumulated travel time of the resulting route.

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 is time-based

This field value must be greater than or equal to zero, and its units are 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 is distance-based

The field value must be greater than or equal to zero, and its units are 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 impedance attribute 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.

Learn more about bearing and bearing tolerance

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.

Learn more about bearing and bearing tolerance

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.

Example 3: Specifying point barriers using a URL

The URL makes a query for a few features from a map service. A URL querying features from a feature service can also be specified.

}

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.

Two maps demonstrate how a line barrier affects finding a route between two stops.
The first map displays the shortest path between two stops. The second map shows the shortest path when several streets are blocked by a polyline barrier.

You can specify polyline barrier geometries as well as attributes using a JSON structure that references a set of features. The property is optional; however, the JSON structure must specify either the url or features property:

  • url—Specify a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set.

  • features—Specify an array of features.

    Each feature in this array represents a polyline barrier and contains the following fields:

    • geometry—Specify the input point geometry containing x and y properties along with the spatialReference property. If the spatialReference property is defined for the entire JSON, you don't need to define this property for each geometry. Doing so reduces the size of the input JSON if the input has many features and improves performance. This property is not required if the coordinates are in the default spatial reference, WGS84. If the coordinates are in a different spatial reference, you must specify the spatial reference's well-known ID (WKID). See Using spatial references to look up WKID values.

Attributes for line_barriers

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.

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.

You can specify polygon barrier geometries as well as attributes using a JSON structure that references a set of features. The JSON structure can be specified as a url or features property:

  • url—Specify a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set.

  • features—Specify an array of features.

    Each feature in this array represents a polygon barrier and contains the following fields:

    • geometry—Specify the input point geometry containing x and y properties along with the spatialReference property. If the spatialReference property is defined for the entire JSON, you don't need to define this property for each geometry. Doing so reduces the size of the input JSON if the input has many features and improves performance. This property is not required if the coordinates are in the default spatial reference, WGS84. If the coordinates are in a different spatial reference, you must specify the spatial reference's well-known ID (WKID). See Using spatial references to look up WKID values.
      Tip:

      It is recommended that you explicitly specify the spatialReference value, and specify it for the entire JSON rather than each individual geometry.

    • attributes—Specify each attribute as a key-value pair in which the key is the name of a given field, and the value is the attribute value for the corresponding field.

Attributes for polygon_barriers

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.

      This is the default value.

      Two maps demonstrate how a restriction polygon barrier affects finding a route between two stops.
      The first map depicts the shortest path between two stops. The second map shows a polygon barrier blocking flooded streets, so the shortest path between the same two stops is different.

    • 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.

      Two maps demonstrate how a scaled cost polygon barrier affects finding a route between two stops.
      The first map shows a route that goes through inclement weather without regard for the effect that poor road conditions have on travel time. The second map shows a scaled polygon barrier that doubles the travel time of the roads covered by the storm. The route still passes through the southern tip of the storm since it is quicker to spend more time driving slowly through a small part of the storm rather than driving completely around it. The service uses the modified travel time in calculating the best route, and the modified travel time is reported as the total travel time in the response.

  • 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 impedance is neither time-based nor distance-based .

Examples for polygon_barriers

Example 1: Specifying polygon barriers using a JSON structure.

The example shows how to add two polygons as barriers. The first polygon named Flood zone is a restriction polygon barrier that prohibits travel on the underlying streets. The polygon is a single-part polygon feature made up of four points. The second polygon named Severe weather zone is a scaled-cost polygon barrier that increases the travel time on underlying streets to one third of the original value. The polygon is a two-part polygon feature. Both parts are made up of four points.

Example 2: Specifying a polygon barrier using a URL

The URL makes a query for a few features from a map service. A URL querying features from a feature service can also be specified.

uturn_at_junctions

Use this parameter to restrict or permit the route from making U-turns at junctions.

Caution:

The value of this parameter, regardless of whether you rely on the default or explicitly set a value, is overridden when travel_mode is set to any other value than Custom. The default value for travel_mode is Driving, so unless you set travel_mode to a different value, this parameter value will be overridden.

To understand the available parameter values, a junction is a point where only two streets intersect each other. If three or more streets intersect at a point, it is called as an intersection. A cul-de-sac is a dead-end. This parameter can have the following values:

Parameter ValueDescription

Allowed

U-turns are permitted everywhere. Permitting U-turns implies that the vehicle can turn around at a junction and double back on the same street.

U-turns permitted
U-turns are permitted at junctions with any number of adjacent streets.

Allowed only at Intersections and Dead Ends

U-turns are prohibited at junctions where exactly two adjacent streets meet.

U-turns permitted only at intersections and dead-ends
U-turns are permitted only at intersections or dead ends.

Allowed only at Dead Ends

U-turns are prohibited at all junctions and intersections and are permitted only at dead ends.

U-turns permitted only at dead-ends
U-turns are permitted only at dead ends.

Not Allowed

U-turns are prohibited at all junctions, intersections, and dead-ends. Even when this parameter value is chosen, a route can still make U-turns at stops. To prohibit U-turns at a stop, you can set its CurbApproach property to the appropriate value (3).

The default value for this parameter is Allowed only at Intersections and Dead Ends.

use_hierarchy

Specify whether hierarchy will be used when finding the destinations.

The default value for this parameter is true.

Caution:

The value of this parameter, regardless of whether you rely on the default or explicitly set a value, is overridden when travel_mode is set to any other value than Custom. The default value for travel_mode is Driving, so unless you set travel_mode to a different value, this parameter value will be overridden.

  • true—Use hierarchy when travelling from origins to destinations. When hierarchy is used, the service prefers higher-order streets (such as freeways) to 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 true 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, since the service can determine the best route from a relatively smaller subset of streets.

  • false—Do not use hierarchy when travelling from origins to destinations. If hierarchy is not used, the service considers all the streets and doesn't prefer higher-order streets. This is often used when solving problems in a small area with a lot of destination but are specifying a cutoff based on a subset of them.

restrictions

Use this parameter to specify the restrictions that will be honored by the service. A restriction represents a driving preference or requirement. In most cases, restrictions cause roads or pathways to be prohibited, but they can also cause them to be avoided or preferred. 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 a stop. Use Height Restriction to route around clearances that are lower than the height of the vehicle. If the vehicle is carrying corrosive materials, you can use the Any Hazmat Prohibited restriction to prevent hauling the materials along roads where it is marked as illegal to do so.

Caution:

The value of this parameter, regardless of whether you rely on the default or explicitly set a value, is overridden when you pass in travel_mode.

This parameter value is specified as a comma-separated list of restriction names. A value of none indicates that no restrictions will be used when finding the shortest paths.

The service supports the following restriction names:

  • Any Hazmat Prohibited—The results will not include roads where transporting any kind of hazardous material is prohibited.

  • Avoid Carpool Roads—The results will avoid roads that are designated exclusively for car pool (high-occupancy) vehicles.

  • Avoid Express Lanes—The results will avoid roads designated as express lanes.

  • Avoid Ferries—The results will avoid ferries.

  • Avoid Gates—The results will avoid roads where there are gates, such as keyed access or guard-controlled entryways.

  • Avoid Limited Access Roads—The results will avoid roads that are limited-access highways.

  • Avoid Private Roads—The results will avoid roads that are not publicly owned and maintained.

  • Avoid Roads Unsuitable for Pedestrians—The results will avoid roads that are unsuitable for pedestrians.

  • Avoid Stairways—The results will avoid all stairways on a pedestrian-suitable route.

  • Avoid Toll Roads—The results will avoid all toll roads for automobiles.

  • Avoid Toll Roads for Trucks—The results will avoid all toll roads for trucks.

  • Avoid Truck Restricted Roads—The results will avoid roads where trucks are not allowed, except when making deliveries.

  • Avoid Unpaved Roads—The results will avoid roads that are not paved (for example, dirt, gravel, and so on).

  • Axle Count Restriction—The results will not include roads where trucks with the specified number of axles are prohibited. The number of axles can be specified using the Number of Axles restriction parameter.

  • Driving a Bus—The results will not include roads where buses are prohibited. Using this restriction will also ensure that the results will honor one-way streets.

  • Driving a Taxi—The results will not include roads where taxis are prohibited. Using this restriction will also ensure that the results will honor one-way streets.

  • Driving a Truck—The results will not include roads where trucks are prohibited. Using this restriction will also ensure that the results will honor one-way streets.

  • Driving an Automobile—The results will not include roads where automobiles are prohibited. Using this restriction will also ensure that the results will honor one-way streets.

  • Driving an Emergency Vehicle—The results will not include roads where emergency vehicles are prohibited. Using this restriction will also ensure that the results will honor one-way streets.

  • Height Restriction—The results will not include roads where the vehicle height exceeds the maximum allowed height for the road. The vehicle height can be specified using the Vehicle Height (meters) restriction parameter.

  • Kingpin to Rear Axle Length Restriction—The results will not include roads where the vehicle length exceeds the maximum allowed kingpin to rear axle for all trucks on the road. The length between the vehicle kingpin and the rear axle can be specified using the Vehicle Kingpin to Rear Axle Length (meters) restriction parameter.

  • Length Restriction—The results will not include roads where the vehicle length exceeds the maximum allowed length for the road. The vehicle length can be specified using the Vehicle Length (meters) restriction parameter.

  • Preferred for Pedestrians—The results will use preferred routes suitable for pedestrian navigation.

  • Riding a Motorcycle—The results will not include roads where motorcycles are prohibited. Using this restriction will also ensure that the results will honor one-way streets.

  • Roads Under Construction Prohibited—The results will not include roads that are under construction.

  • Semi or Tractor with One or More Trailers Prohibited—The results will not include roads where semis or tractors with one or more trailers are prohibited.

  • Single Axle Vehicles Prohibited—The results will not include roads where vehicles with single axles are prohibited.

  • Tandem Axle Vehicles Prohibited—The results will not include roads where vehicles with tandem axles are prohibited.

  • Through Traffic Prohibited—The results will not include roads where through traffic (nonlocal traffic) is prohibited.

  • Truck with Trailers Restriction—The results will not include roads where trucks with the specified number of trailers on the truck are prohibited. The number of trailers on the truck can be specified using the Number of Trailers on Truck restriction parameter.

  • Use Preferred Hazmat Routes—The results will prefer roads that are designated for transporting hazardous materials.

  • Use Preferred Truck Routes—The results will prefer roads that are designated as truck routes, such as roads that are part of the national network as specified by the National Surface Transportation Assistance Act in the United States, or roads that are designated as truck routes by the state or province, or roads that are preferred by truckers when driving in an area.

  • Walking—The results will not include roads where pedestrians are prohibited.

  • Weight Restriction—The results will not include roads where the vehicle weight exceeds the maximum allowed weight for the road. The vehicle weight can be specified using the Vehicle Weight (kilograms) restriction parameter.

  • Weight per Axle Restriction—The results will not include roads where the vehicle weight per axle exceeds the maximum allowed weight per axle for the road. The vehicle weight per axle can be specified using the Vehicle Weight per Axle (kilograms) restriction parameter.

  • Width Restriction—The results will not include roads where the vehicle width exceeds the maximum allowed width for the road. The vehicle width can be specified using the Vehicle Width (meters) restriction parameter.

Note:

These value are specific to the services published with the ArcGIS StreetMap Premium data. The values will be different if you are using other data for the analysis.

Legacy:

The Driving a Delivery Vehicle restriction attribute is no longer available. The service will ignore this restriction since it is invalid. To achieve similar results, use the Driving a Truck restriction attribute along with the Avoid Truck Restricted Roads restriction attribute.

The restrictions parameter value is specified as a list of restriction names. A value of null indicates that no restrictions should be used when finding the best route, but only when travel_mode is set to Custom.

Example for restrictions

restrictions=[Driving a Truck, Height Restriction, Length Restriction]

attribute_parameter_values

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.

Caution:

The value of this parameter, regardless of whether you rely on the default or explicitly set a value, is overridden when you pass in travel_mode parameter.

You can specify attribute_parameter_values parameter using JSON structure that represents a set of features. The JSON structure can include the following properties:

  • features—Specify an array of features.

    • geometry—Specify the input point geometry containing x and y properties along with the spatialReference property. If the spatialReference property is defined for the entire JSON, you don't need to define this property for each geometry. Doing so reduces the size of the input JSON if the input has many features and improves performance. This property is not required if the coordinates are in the default spatial reference, WGS84. If the coordinates are in a different spatial reference, you must specify the spatial reference's well-known ID (WKID). See Using spatial references to look up WKID values.
      Tip:

      It is recommended that you explicitly specify the spatialReference value, and specify it for the entire JSON rather than each individual geometry.

    • attributes—Specify each attribute as a key-value pair in which the key is the name of a given field, and the value is the attribute value for the corresponding field.
  • url—Specify a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set.

Each feature in the features array represents an attribute parameter and contains the following fields:

  • attributes—Specify each attribute as a key-value pair in which the key is the name of a given field, and the value is the attribute value for the corresponding field.
Note:

The JSON structure for the attribute_parameter_values parameter does not have a geometry property.

Attributes for attribute_parameter_values

The attribute_parameter_values parameter can be specified with the following attributes:

  • AttributeName—The name of the restriction.
  • ParameterName—The name of the parameter associated with the restriction. A restriction can have one or more ParameterName values based on its intended use, which implies you may need multiple attribute_parameter_values parameters for a single attribute name.
  • ParameterValue—The value for the ParameterName that is used by the service when evaluating the restriction.

Note:

In most cases, the attribute_parameter_values parameter is dependent on the restrictions parameter. The ParameterValue specified as part of attribute_parameter_values is applicable only if the restriction name is specified as the value for the restrictions parameter.

When specifying the attribute_parameter_values parameter, each restriction (listed as AttributeName) has a ParameterName value, Restriction Usage, that specifies whether the restriction prohibits, avoids, or prefers travel on the roads associated with the restriction and the degree to which the roads are avoided or preferred.

The Restriction Usage value for the ParameterName attribute can be assigned any of the following string values or their equivalent numeric values listed in the parentheses:

  • Prohibited (-1)—Travel on the roads that have the restriction is prohibited.
  • Avoid_High (5)—It is very unlikely the service will include in the route the roads that are associated with the restriction.
  • Avoid_Medium (2)—It is unlikely the service will include in the route the roads that are associated with the restriction.
  • Avoid_Low (1.3)—It is somewhat unlikely the service will include in the route the roads that are associated with the restriction.
  • Prefer_Low (0.8)—It is somewhat likely the service will include in the route the roads that are associated with the restriction.
  • Prefer_Medium(0.5)—It is likely the service will include in the route the roads that are associated with the restriction.
  • Prefer_High (0.2)—It is very likely the service will include in the route the roads that are associated with the restriction.

The following table lists the restriction names and the default restriction parameter values for all the restrictions. The default value for the attribute_parameter_values parameter is the JSON structure containing all the rows from the below table.

Tip:

If you want to use the default value for any restriction, AttributeName, ParameterName, and ParameterValue do not have to be specified as part of the attribute_parameter_values parameter.

Example for attribute_parameter_values

Example: Specifying the vehicle height and weight and a high preference to use designated truck routes

This example shows how to specify the height and weight of the vehicle for use with the height and weight restrictions respectively along with a high preference to include designated truck routes. This results in a route that does not include any roads where the clearance under overpasses or through tunnels is less than the vehicle height. The results will also not include any roads with load limited bridges or local roads that prohibit heavy vehicles if the vehicle weight exceeds the maximum permissible weight. However, the route will include as many roads as possible that are designated as preferred truck routes.

Note that the Restriction Usage ParameterName for the Height Restriction and the Weight Restriction restrictions are not specified since we want to use the default value of PROHIBITED for these restriction parameters.

}

impedance

Specify the impedance.

Caution:

The value of this parameter, regardless of whether you rely on the default or explicitly set a value, is overridden when you pass in travel_mode.

Impedance is a value that quantifies travel along the transportation network. Travel distance is an example of impedance; it quantifies the length of walkways and road segments. Similarly, drive time—the typical time it takes to drive a car along a road segment—is an example of impedance. Drive times may vary by type of vehicle—for instance, the time it takes for a truck to travel along a path tends to be longer than a car—so there can be many impedance values representing travel times for different vehicle types. Impedance values may also vary with time; live and typical traffic reference dynamic impedance values. Each walkway and road segment stores at least one impedance value. When performing a network analysis, the impedance values are used to calculate the best results, such as finding the shortest route—the route that minimizes impedance—between two points.

The impedance parameter can be specified using the following values:

  • TravelTime—Historical and live traffic data is used. This option is good for modeling the time it takes automobiles to travel along roads at a specific time of day using live traffic speed data where available. When using TravelTime, you can optionally set the TravelTime::Vehicle Maximum Speed (km/h) attribute parameter to specify the physical limitation of the speed the vehicle is capable of traveling.
  • Minutes—Live traffic data is not used, but historical average speeds for automobiles data is used.
  • TruckTravelTime—Historical and live traffic data is used, but the speed is capped at the posted truck speed limit. This is good for modeling the time it takes for the trucks to travel along roads at a specific time. When using TruckTravelTime, you can optionally set the TruckTravelTime::Vehicle Maximum Speed (km/h) attribute parameter to specify the physical limitation of the speed the truck is capable of traveling.
  • TruckMinutes—Live traffic data is not used, but the smaller of the historical average speeds for automobiles and the posted speed limits for trucks are 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.
Note:

These value are specific to the services published with the ArcGIS StreetMap Premium data. The values will be different if you are using other data for the analysis.

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, Kilometers, the 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.

origin_destination_line_shape

Specify the shape of the line feature connecting each origin-destination pair in the output matrix. The resulting lines of an origin-destination 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.

The parameter accepts one of the following values:

  • 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 origin-destination cost matrix table (and not the output line shapes).

The default value is None

save_output_network_analysis_layer

Use this parameter to specify if the service should save the analysis settings as a network analysis layer file. You cannot directly work with this file even when you open the file in an ArcGIS Desktop application like ArcGIS Pro. It is meant to be sent to Esri Technical Support in order to diagnose the quality of results returned from the service.

  • true—Saves network analysis layer file. The file can be downloaded from the URL provided as part of the output_network_analysis_layer parameter.
  • false—Don't save network analysis layer file.

The default value is false.

overrides

Note:

This parameter is for internal use only.

time_impedance

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

  • Minutes
  • TravelTime
  • WalkTime
  • TruckMinutes
  • TruckTravelTime

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.
Note:

This parameter is used for defining a custom travel mode. The value of this parameter is ignored if the travel_mode parameter is not set to Custom.

Note:

These value are specific to the services published with the ArcGIS StreetMap Premium data. The values will be different if you are using other data for the analysis.

distance_impedance

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

  • Miles
  • 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.
Note:

This parameter is used for defining a custom travel mode. The value of this parameter is ignored if the travel_mode parameter is not set to Custom.

Note:

These value are specific to the services published with the ArcGIS StreetMap Premium data. The values will be different if you are using other data for the analysis.

output_format

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

Choose from the following formats:

  • 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 value (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.

Tip:

Specifying file based output format, such asJSON File, is useful when you are calling the service using the REST endpoint of the service. In such cases, returning all the outputs as a single file allows you to download large results that can be generated by the service. For example, if you are working with GenerateOriginDestinationCostMatrix service and you generate a travel matrix with 1,000,000 records, returning such a large output as a Feature Set can cause the service to fail since the service will try to send the entire output in a single attempt. With a file based output, the service sends the output in multiple chunks reducing the possibility of timeouts when returning the outputs.

env:outSR

Use this parameter to specify the spatial reference of the geometries, such as line or point features, returned by the service.

The parameter value can be specified as a well-known ID (WKID) for the spatial reference. See Using spatial references to look up WKID values.

Many of the basemaps provided by ArcGIS Online are in the Web Mercator spatial reference (WKID 102100). Specifying env:outSR=102100 returns the geometries in the Web Mercator spatial reference, which can be drawn on top of the basemaps.

ignore_network_location_fields

Specifies whether the network location fields will be considered when locating inputs such as stops or facilities on the network.

  • true—Network location fields will not be considered when locating the inputs on the network. Instead, the inputs will always be located by performing a spatial search.
  • false—Network location fields will be considered when locating the inputs on the network.

The default value is false.

ignore_invalid_locations

Specifies whether invalid input locations will be ignored.

  • true

    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.

  • false

    Invalid locations will not be ignored. Do not run the analysis if there are invalid locations. Correct the invalid locations and rerun the analysis.

locate_settings

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. To restrict locating on a portion of the source, you can specify a where clause for a source.

Learn more about locating inputs

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.

Note:

The default value for this parameter can be obtained from the service resource JSON. Append ?token=<yourToken>&f=pjson to the service URL to access the service resource JSON.

The locator JSON object has the following properties:

  • tolerance and toleranceUnits—Allows you to control the maximum search distance when locating inputs. If no valid network location is found within this distance, the input features will be considered unlocated. A small search tolerance decreases the likelihood of locating on the wrong street but increases the likelihood of not finding any valid network location. The toleranceUnits parameter value can be specified as one of the following values:
    • esriCentimeters
    • esriDecimalDegrees
    • esriDecimeters
    • esriFeet
    • esriInches
    • esriIntFeet
    • esriIntInches
    • esriIntMiles
    • esriIntNauticalMiles
    • esriIntYards
    • esriKilometers
    • esriMeters
    • esriMiles
    • esriMillimeters
    • esriNauticalMiles
    • esriYards
  • sources—Allows you to control which network source can be used for locating. For example, you can configure the analysis to locate inputs on streets but not on sidewalks. The list of possible sources on which to locate is specific to the network dataset this service references. Only the sources that are present in the sources array are used for locating. You can specify a whereclause on each source you specified in the sources array to further restrict locating on that source matching certain characteristics using an SQL expression. For example, you can configure the analysis to locate inputs only on street features matching certain road classes such as avoiding highway ramps. Sources is specified as an array of objects, each having the following properties:
    • name—Name of the network source feature class that can be used for locating inputs.
    • where—An SQL expression on the network source feature class.
  • 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.

Examples for locate_settings

Example 1: Specify default locate settings using JSON structure

This example shows how to specify locate settings so inputs are only located within 500 meters of the specified location. A small search tolerance like this can be valuable if you are solving using a walking travel mode and don't want inputs to be located farther than 500 meters from the original point location.


{
  "default": {
    "tolerance": 500,
    "toleranceUnits": "esriMeters",
    "allowAutoRelocate": true,
    "sources": [
      {
        "name": "Routing_Streets"
      }
    ]
  }
}

Example 2: Specify default locate settings and locate settings overrides for some inputs using JSON structure

This example shows how to specify locate settings to prevent origins and destinations from locating on highway ramps. The default locate settings to allow locating on the Routing_Streets source. For origins and destinations, the overrides option is used to specify a where clause for the Routing_Streets source to prevent locating on highway ramps (a ROAD_CLASS field value of 3). With this locate_settings json, origins and destinations cannot locate on highway ramps, but barriers can because they use the default locate settings, which do not include a where clause.


{
    "default": {
        "tolerance": 20,
        "toleranceUnits": "esriKilometers",
        "allowAutoRelocate": true,
        "sources": [{
            "name": "Routing_Streets"
        }]
    },
    "overrides": {
        "origins": {
            "sources": [{
                "name": "Routing_Streets",
                "where": "ROAD_CLASS <> 3"
            }]
        },
        "destinations": {
            "sources": [{
                "name": "Routing_Streets",
                "where": "ROAD_CLASS <> 3"
            }]
        }
    }
}

Example three: Specify default locate settings and locate settings overrides using JSON structure so different inputs are located using different sources.

This example shows how to specify default locate settings to locate inputs on Routing_Streets source feature class while allowing point barriers to only locate on the system junctions feature class (Routing_ND_Junctions).


{
    "default": {
        "tolerance": 20,
        "toleranceUnits": "esriKilometers",
        "allowAutoRelocate": true,
        "sources": [{
            "name": "Routing_Streets"
        }]
    },
    "overrides": {
        "point_barriers": {
            "sources": [{
                "name": "Routing_ND_Junctions"
            }]
        }
    }
}

accumulate_attributes

A list of cost attributes to be accumulated during analysis. These accumulated attributes are for reference only; the solver only uses the cost attribute used by the designated travel mode when solving the analysis.

For each cost attribute that is accumulated, a Total_[Cost Attribute Name]_[Units] field is populated in the outputs created from the tool.

solve_succeeded

Specify whether the service successfully generated the origin-destination cost matrix. The error messages for a failure can be obtained by making a request to get the status of the job.

The solve_succeeded parameter is returned as a JSON feature set with the following syntax:


{
  "paramName": "solve_succeeded",
  "dataType": "GPBoolean",
  "value": <true | false>
}

The following shows an example of the solve_succeeded parameter:


{
  "paramName": "solve_succeeded",
  "dataType": "GPBoolean",
  "value": true
}

Example usage

This service uses the asynchronous execution mode. The client must periodically check whether the service has completed execution and, once complete, get the result. While the service is executing, you can use the application for other things.

Caution:

The maximum time an application can use the Origin Destination Cost Matrix service is 1 hour (3,600 seconds). If your request does not complete within this time limit, it will time out and fail.

You can make a request to the Origin Destination Cost Matrix service using the following form:

https://<gpservice-url>/GenerateOriginDestinationCostMatrix/submitJob?parameters

In this example, you will generate an origin-destination cost matrix between two origins and two destinations. The resulting origin-destination cost matrix will have four features.

The origins and destinations are in the same spatial reference as your network dataset, so the spatialReference property is not required.

Generate a travel cost matrix

The following generate a travel cost matrix.

Return the output origin-destination lines

Because the job succeeded, the travel time and travel distance between every origin-destination pair can be obtained using the output_origin_destination_lines output parameter. Since you did not specify a value for the origin_destination_line_shape parameter, the default value, None, was used by the service for this parameter. Consequently, the features array in the output response does not have the geometry property.

JSON Response syntax

When you submit a request, the service assigns a unique job ID to the transaction. The job ID and the status of the job are returned in the response.


{
  "jobId": <jobID>,
  "jobStatus": <jobStatus>
}

The jobStatus property can have the following values:

  • esriJobSubmitted
  • esriJobWaiting
  • esriJobExecuting
  • esriJobSucceeded
  • esriJobFailed
  • esriJobTimedOut
  • esriJobCancelling
  • esriJobCancelled

You can use the job ID to periodically check the status of the job and messages. Additionally, if the job has successfully completed, you can use the job ID to retrieve the results or the inputs. The job information and results remain available for 24 hours after the job is complete.

Job execution

After the initial request is submitted, you can make a request of the following form to get the status of the job:

https://<gpservice-url>/GenerateOriginDestinationCostMatrix/jobs/<yourJobID>/?token=<yourToken>&returnMessages=true&f=json

The example below demonstrates the JSON response syntax returned when using the request above:


{
  "jobId": "<jobId>",
  "jobStatus": "<jobStatus>",
  "messages": [
    {
      "type": "<type1>",
      "description": "<description1>"
    },
    {
      "type": "<type2>",
      "description": "<description2>"
    }
  ]
}

While a job is running, you can cancel it by making a request of the following form:

https://<gpservice-url>/GenerateOriginDestinationCostMatrix/jobs/<jobID>/cancel?token=<yourToken>&f=json
Note:

When you submit your request, if the service is processing other requests, the job will remain in the queue. The job status will be reported as esriJobSubmitted. If you cannot wait for the entire duration while the job is in the queue, you can cancel the request and submit it at a later time. A canceled request will not incur service credits. However, if you do not cancel the request, it will eventually run and will incur service credits regardless of whether the application retrieved the results or ignored them. Therefore, it is recommended that you cancel the request if necessary.

Job completion

After the successful completion of the job, you can make a request of the following form to retrieve the outputs. Refer to the Output parameters section for more information on how to interpret the solution provided by the service.

https://<gpservice-url>/GenerateOriginDestinationCostMatrix/jobs/<jobID>/results/<output_parameter_name>?token=<yourToken>&f=pjson

You can also retrieve the value for any input parameter by making a request of the following form:

https://<gpservice-url>/GenerateOriginDestinationCostMatrix/jobs/<jobID>/inputs/<input_parameter_name>?token=<yourToken>f=pjson

Usage limits

The following table lists the limits that apply to this service:

Limit valueLimit description

12.42 miles (20 kilometers)

4 hours

Maximum time a client can use the asynchronous service

10,000,000

Maximum number of features that can be returned by the asynchronous service

The limit for snap tolerance cannot be changed, however you can configure other limits by following the steps below:

  1. Open Server Manager for the ArcGIS Server site that contains the NetworkAnalysis geoprocessing service and sign in. If you need help with this step, see Log in to Manager.
  2. Click Services > Manage Services.
  3. In the Manage Services module, locate NetworkAnalysis geoprocessing service and click Edit Service Edit.

    If you don't see the service under the Routing folder, it may be located within another folder under the Site (root) >.

  4. Click the Parameters option and change the limit for the number of records returned by the service by editing the value in Maximum Number of Records Returned by Server text box.
  5. Click the Pooling option and change the maximum time the service can be used by editing the value in the The maximum time a client can use a service text box.
  6. Click Save and Restart to apply your edits and restart the service.
