Update at 11.0

• Use locateSettings to specify settings that affect how inputs are located.
• Use returnEmptyResults to return empty results instead of error when the request fails.

Specify whether the service will return empty results instead of the error property when the request fails.

Updates at 10.9.1

Use geometryPrecision and geometryPrecisionZ to specify the output geometry precision for X, Y, and Z coordinates.

origins

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

You can use a simple comma- and semicolon-based syntax if you are passing the input locations using their longitude and latitude values in the WGS84 coordinate system and don't need to pass additional fields for each location.

Simple syntax for origins

origins=x1,y1; x2, y2; ...; xn, yn

Example using simple syntax

origins=-117.1957,34.0564; -117.184,34.0546

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

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

  The JSON structure can include the following property:

  • doNotLocateOnRestrictedElements (optional)—Specify whether the restricted network elements will be considered when finding network locations. The default is true.

• 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.

  The JSON structure can include the following property:

  • doNotLocateOnRestrictedElements (optional)—Specify whether the restricted network elements will be considered when finding network locations. The default is true.

• layer—Specify a feature layer in the map service. Attribute and spatial filters can also be applied on the layer. The JSON structure can include the following properties:
  • type—The type should be set to layer to indicate that the user is specifying the origins by referencing a layer.
  • layerName—The name or ID of the data layer in the map service that is being referenced.
  • where (optional)—A WHERE clause for the query filter. Any legal SQL WHERE clause operating on the fields in the layer is allowed.
  • geometry (optional)—The geometry to apply as the spatial filter. The structure of the geometry is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API.

    The geometry type is specified using the geometryType property.

  • geometryType (optional)—The type of geometry specified by the geometry property. The supported geometry types are envelope, point, line, and polygon. The default geometry type is esriGeometryEnvelope.

    Values: esriGeometryPoint | esriGeometryMultipoint | esriGeometryPolyline | esriGeometryPolygon | esriGeometryEnvelope

  • spatialRel (optional)—The spatial relationship to be applied to the input geometry. The supported spatial relationships include intersects, contains, envelope intersects, within, and so on. The default spatial relationship is esriSpatialRelIntersects.

    Values: esriSpatialRelIntersects | esriSpatialRelContains | esriSpatialRelCrosses | esriSpatialRelEnvelopeIntersects | esriSpatialRelIndexIntersects | esriSpatialRelOverlaps | esriSpatialRelTouches | esriSpatialRelWithin

  • doNotLocateOnRestrictedElements (optional)—Specify whether the restricted network elements will be considered when finding network locations. The default is true.

defaultCutoff

Use this parameter to specify the travel time or travel distance value at which to stop searching for destinations from a given origin.

The unit for this parameter is based on the unit of the impedance attribute specified using the impedanceAttributeName parameter or the impedanceAttributeName value of the travel mode if a travel mode is specified . If the impedanceAttributeName parameter is TravelTime, the defaultCutoff value is specified in minutes. Otherwise, the value is specified in miles or kilometers based on whether the impedanceAttributeName parameter is set to Miles or Kilometers, respectively.

The value for the defaultCutoff parameter can be overridden on a per-origin basis by specifying a value for the Cutoff_[Impedance] attribute when specifying the origins parameter value.

defaultTargetDestinationCount

The maximum number of destinations to find per origin. If a value for this parameter is not specified, the output matrix includes travel costs from each origin to every destination.

The value for the defaultTargetDestinationCount parameter can be overridden by specifying a value for the TargetDestinationCount attribute when specifying the origins parameter.

outputType

Specify the type of route features that are output by the service. The outputType parameter can have one of the following values:

• esriNAODOutputSparseMatrix—Return the cost between origin and destination using a sparse matrix format.
• esriNAODOutputStraightLines—Return a straight line between the origin and the destination.
• esriNAODOutputNoLines—Do not return any shapes for the result.

timeOfDay

The time and date to depart from the origins. You can also specify a value of now to set the depart time from origins to the current time.

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, set impedanceAttributeName to TravelTime, and assign a timeOfDay value.

The timeOfDay 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 value of now is passed to the timeOfDay parameter, the travel begins at the current time. This will also override the timeOfDayIsUTC parameter value to be true. When timeOfDay is nowand timeOfDayIsUTC is true, the travel will begin or end at input locations at the current time regardless of the time zone of the input locations.

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.

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

If the timeOfDay value specified is within four 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 timeOfDay value specified is more than four hours earlier or later than 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. Consequently, a road may have a different travel time at Monday at 8:00 a.m., Monday at 8:15 a.m., or Tuesday at 8:00 a.m.. Since the variance is at the day of week and time of day, the travel time is the same on a road for any Monday at 8:00 a.m., regardless of the month or year.

"timeOfDay": 1426674000000

timeOfDayIsUTC

Specify the time zone or zones of the timeOfDay parameter.

False (use geographically local time zones)

The timeOfDay 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.

The following image illustrates setting the value to false (geographically local). Setting timeOfDay to 9:00 a.m., January 4, 1990 (631443600000 milliseconds) and timeOfDayIsUTC to false, and submitting a valid request causes the drive times for points in the eastern time zone to start at 9:00 a.m. 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.)

True (use UTC)

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

The following image illustrates setting the value to true (UTC). Setting timeOfDay to 9:00 a.m., January 4, 1990 (631443600000 milliseconds) and timeOfDayIsUTC to true causes the start time for points in the eastern time zone to be 4:00 a.m. eastern time and 3:00 a.m. central time for those in the central time zone.

useHierarchy

Specify whether hierarchy will be used when finding the destinations.

• 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.

restrictUTurns

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

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 value	Description
esriNFSBAllowBacktrack	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.
esriNFSBAtDeadEndsAndIntersections	U-turns are prohibited at junctions where exactly two adjacent streets meet.
esriNFSBAtDeadEndsOnly	U-turns are prohibited at all junctions and intersections and are permitted only at dead ends.
esriNFSBNoBacktrack	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).

impedanceAttributeName

Specify the impedance.

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 impedanceAttributeName 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.

accumulateAttributeNames

Use this parameter to specify whether the service will accumulate values other than the value specified for impedanceAttributeName. For example, if impedanceAttributeName is set to TravelTime, the total travel time for the route will be calculated by the service. However, if you also want to calculate the total distance of the route in miles, you can specify Miles as the value for the accumulateAttributeNames parameter.

Specify the parameter value as a comma-separated list of names. The parameter values are the same as the impedanceAttributeName parameter. For example, accumulateAttributeNames=Miles,Kilometers indicates that the total cost of the route will also be calculated in miles and kilometers.

restrictionAttributeNames

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.

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 restrictionAttributeNames parameter can be specified using the following values:

• 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.

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

attributeParameterValues

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.

This parameter value is specified as an array of objects each having the following properties:

• attributeName—The name of the restriction.

• parameterName—The name of the parameter associated with the restriction. A restriction can have one or more parameterName properties.

• value—The value for parameterName.

Most attribute parameters are related to the restriction attributes in restrictionAttributeNames. Each restriction has at least one attribute parameter named Restriction Usage, which 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 parameter can be assigned any of the following string values or their equivalent numeric values 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.

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 use a simple comma- and semicolon-based syntax if you are passing the point barrier locations using their longitude and latitude values in the WGS84 coordinate system and don't need to pass additional fields for each location.

Simple syntax for barriers

barriers=x1,y1; x2, y2; ...; xn, yn

Example using simple syntax

barriers=-117.1957,34.0564; -117.184,34.0546

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, features, or layer property:

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

  The JSON structure can include the following property:

  • doNotLocateOnRestrictedElements (optional)—Specify whether the restricted network elements will be considered when finding network locations. The default is true.

• 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.

  The JSON structure can include the following property:

  • doNotLocateOnRestrictedElements (optional)—Specify whether the restricted network elements will be considered when finding network locations. The default is true.

• layer—Specify a feature layer in the map service. Attribute and spatial filters can also be applied on the layer. The JSON structure can include the following properties:
  • type—The type should be set to layer to indicate that the user is specifying the point barriers by referencing a layer.
  • layerName—The name or ID of the data layer in the map service that is being referenced.
  • where (optional)—A WHERE clause for the query filter. Any legal SQL WHERE clause operating on the fields in the layer is allowed.
  • geometry (optional)—The geometry to apply as the spatial filter. The structure of the geometry is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API.

    The geometry type is specified using the geometryType property.

  • geometryType (optional)—The type of geometry specified by the geometry property. The supported geometry types are envelope, point, line, and polygon. The default geometry type is esriGeometryEnvelope.

    Values: esriGeometryPoint | esriGeometryMultipoint | esriGeometryPolyline | esriGeometryPolygon | esriGeometryEnvelope

  • spatialRel (optional)—The spatial relationship to be applied to the input geometry. The supported spatial relationships include intersects, contains, envelope intersects, within, and so on. The default spatial relationship is esriSpatialRelIntersects.

    Values: esriSpatialRelIntersects | esriSpatialRelContains | esriSpatialRelCrosses | esriSpatialRelEnvelopeIntersects | esriSpatialRelIndexIntersects | esriSpatialRelOverlaps | esriSpatialRelTouches | esriSpatialRelWithin

  • doNotLocateOnRestrictedElements (optional)—Specify whether the restricted network elements will be considered when finding network locations. The default is true.

polylineBarriers

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.

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, features, or layer property:

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

  The JSON structure can include the following property:

  • doNotLocateOnRestrictedElements (optional)—Specify whether the restricted network elements will be considered when finding network locations. The default is true.

• 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.

    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.

  The JSON structure can include the following property:

  • doNotLocateOnRestrictedElements (optional)—Specify whether the restricted network elements will be considered when finding network locations. The default is true.

• layer—Specify a feature layer in the map service. Attribute and spatial filters can also be applied on the layer. The JSON structure can include the following properties:
  • type—The type should be set to layer to indicate that the user is specifying the polyline barriers by referencing a layer.
  • layerName—The name or ID of the data layer in the map service that is being referenced.

  • geometry (optional)—The geometry to apply as the spatial filter. The structure of the geometry is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API.

    The geometry type is specified using the geometryType property.

  • geometryType (optional)—The type of geometry specified by the geometry property. The supported geometry types are envelope, point, line, and polygon. The default geometry type is esriGeometryEnvelope.

    Values: esriGeometryPoint | esriGeometryMultipoint | esriGeometryPolyline | esriGeometryPolygon | esriGeometryEnvelope

  • spatialRel (optional)—The spatial relationship to be applied to the input geometry. The supported spatial relationships include intersects, contains, envelope intersects, within, and so on. The default spatial relationship is esriSpatialRelIntersects.

polygonBarriers

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 property is optional however, the JSON structure must specify either the url, features, or layer property:

returnOrigins

Use this parameter to specify whether origins will be returned by the service. The possible values for this parameter are true or false. A true value indicates that the origins used as input will be returned as part of the origins property in the JSON response. The default value for this parameter is false.

If you specified the origins parameter value using a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set, you can set the returnOrigins parameter to true so you can draw the origin locations in the application. You can also set the returnOrigins property to true to determine whether the origins were successfully located on the street network or had other errors by reviewing the Status property in the JSON response.

returnDestinations

Use this parameter to specify whether destinations will be returned by the service. The possible values for this parameter are true or false. A true value indicates that the destinations used as input will be returned as part of the destinations property in the JSON response. The default value for this parameter is false.

If you specified the destinations parameter value using a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set, you can set the returnDestinations parameter to true so you can draw the destination locations in the application. You can also set the returnDestinations property to true to determine whether the destinations were successfully located on the street network or had other errors by reviewing the Status property in the JSON response.

returnBarriers

Specify whether barriers will be returned by the service.

• true—The input point barriers are returned as part of the barriers property in the JSON response.
• false—Point barriers are not returned. This is the default.

For this parameter to take effect, you must also specify a value for the barriers parameter.

If you specified the barriers parameter value using a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set, you can set the returnBarriers parameter to true so you can draw the point barrier locations in the application. You can also set the returnBarriers property to true to see where the barriers were located on the street network or, if they weren't located, understand what the problem was by reviewing the Status property in the JSON response.

returnPolylineBarriers

Specify whether polyline barriers will be returned by the service.

• true—The input polyline barriers are returned as part of the polylineBarriers property in the JSON response.
• false—Polyline barriers are not returned. This is the default.

For this parameter to take effect, you must also specify a value for the polylineBarriers parameter.

If you specified the polylineBarriers parameter value using a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set, you can set the returnPolylineBarriers parameter to true so you can draw the polyline barrier locations in the application.

returnPolygonBarriers

Specify whether polygon barriers will be returned by the service.

• true—The input polygon barriers are returned as part of the polygonBarriers property in the JSON response.
• false—Polygon barriers are not returned. This is the default.

For this parameter to take effect, you must also specify a value for the polygonBarriers parameter.

If you specified the polygonBarriers parameter value using a REST query request to any ArcGIS Server feature, map, or geoprocessing service that returns a JSON feature set, you can set the returnPolygonBarriers parameter to true so you can draw the polygon barrier locations in the application.

geometryPrecision

Use this parameter to specify the number of decimal places that will be used in the response geometries returned by the solve operation. This applies to x- and y-values only (not m- or z-values).

geometryPrecision = 3

geometryPrecisionZ

Use this parameter to specify the number of decimal places that will be used in the response geometries returned by the solve operation. This applies to z-values only (not x-, y-, or m-values).

geometryPrecisionZ = 3

returnZ

Include z-values for the returned geometries if supported by the underlying network. The default value is false.

• true—The output geometries will have a z-value.
• false (default)—No x-value is returned.

ignoreInvalidLocations

Specify whether invalid input locations will be ignored when finding the best solution. An input point is deemed invalid by the service if it is not within the maximum snap tolerance of any traversable street.

• true—Invalid points are ignored.
• false—Any invalid point in the request will cause the service to return a failure.

The default value is true.

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 outSR=102100 returns the geometries in the Web Mercator spatial reference, which can be drawn on top of the basemaps.

overrides

locateSettings

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.

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.

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

returnEmptyResults

Specify whether the service will return empty results instead of the error property when the request fails.

• true—The JSON response doesn't contain the error property when the request fails. All errors are returned in the messages property. The response JSON may contain an empty feature set or empty result for the properties you requested.
• false—The JSON response only contains the error property when the request fails.

The default value is false.

Typically when a request fails, the service will return a JSON response that contains the error property. In some cases, you might want to set returnEmptyResults to true so it always returns properties you requested instead of returning an error response to help handle the response in a more consistent way.

Even if the request fails, when you set returnEmptyResults = true, returnOrigins = true, and returnDestinations = true, you can return origins and destinations to investigate why some of them failed to locate.

odLines

When the outputType is esriNAODOutputNoLines or esriNAODOutputStraightLines, the output will be odLines. The odLines output include geometry for the straight line connecting each origin-destination pairs when the outputType is esriNAODOutputStraightLines.

odCostMatrix

When the outputType is esriNAODOutputSparseMatrix, the output is a JSON object that contains an array identified by costAttributeNames to know what cost attributes are in the matrix and in what index. It then has an associative array of origins (identified by their ObjectID), each of which has an associative array of destinations (identified by their ObjectID) containing an array of costs that are in the same order as the costAttributeNames array.

In the example below, TravelTime is the impedance attribute, and Miles and Kilometers are the accumulate attributes used in the analysis. In the returned matrix that contains the time and distance between the origin-destination pair, each nested JSON object is composed of origin ObjectID, destination ObjectID, and the costs from origin to destination in the order defined in costAttributeNames. In the example below, travel from origin ObjectID 1 to destination ObjectID 1 takes 62.88 miles.

"odCostMatrix": {
  "costAttributeNames": [
    "TravelTime",
    "Miles",
    "Kilometers"
  ],
  "1": {
    "1": [
      78.61,
      62.88,
      101.20
    ]
  }
}

origins

Access the origins that participated in the analysis. It provides information about origins that could not be included in the analysis.

The following table describes the attributes of the output origins:

destinations

Access the destinations that participated in the analysis. It provides information about destinations that could not be included in the analysis as well as the total number of origins that were able to reach a given destination.

The following table describes the attributes of the output destinations:

barriers

This provides access to points that act as temporary restrictions or represent additional time or distance that may be required to travel on the underlying streets.

polylineBarriers

This parameter provides access to one or more lines that prohibit travel anywhere the lines intersect the streets.

polygonBarriers

This parameter provides access to polygons that either completely restrict travel or proportionately scale the time or distance required to travel on the streets intersected by the polygons.

Calculate total travel time and distance between two cities

This example shows how to calculate total travel time and distance between two cities (San Diego and Los Angeles), a typical Origin Destination Cost Matrix problem.

Specify the same two cities as the origins and destinations parameter to get travel time and distance traveling between these two cities. Use the JSON structure to specify the origins and destinations parameter in order to specify the Name and ObjectID of the cities that will be included in the service output.
