Property Overview

Property Details

accumulateAttributesString[]

The list of network attribute names to be accumulated with the analysis. For example, which attributes should be returned as part of the response. The default is as defined in the specific routing network layer used in your RouteTask. You can specify any attribute names listed in the Service Directory under Network Dataset -> Network Attributes as Usage Type: esriNAUTCost. See also Understanding the network attribute.

attributeParameterValuesAttributeParamValue

Each element in the array is an object that describes the parameter values.

barriersDataLayer|FeatureSet

The set of point barriers loaded as network locations during analysis. At ArcGIS Server 10.1 an optional url property was added. Use this property to specify a REST query request to a Feature, Map or GP Service that returns a JSON feature set. The url property can be specified using DataFile. Note that either the features or url property should be specified.

declaredClassStringreadonly

The name of the class. The declared class name is formatted as esri.folder.className.

directionsLanguageString

The language used when computing directions. The default is as defined in the specific routing network layer used in your RouteTask. By default, NAServer gets installed with en_US only - it is up to the server administrator to add additional languages.

directionsLengthUnitsString

The length units to use when computing directions. The default is as defined in the specific routing network layer used in your RouteTask.

Known Values: centimeters | decimal-degrees | decimeters | feet | inches | kilometers | meters | miles | millimeters | nautical-miles | points | yards

directionsOutputTypeString

Defines the amount of direction information returned.

Known Values: complete | complete-no-events | instructions-only | standard | summary-only

Default Value: standard

directionsStyleNameString

The style to be used when returning directions. The default will be as defined in the network layer. View the REST layer description for your network service to see a list of supported styles.

directionsTimeAttributeString

The name of network attribute to use for the drive time when computing directions. The default is as defined in the specific routing network layer used in your RouteTask.

doNotLocateOnRestrictedElementsBoolean

If true, avoids network elements restricted by barriers or restrictions specified in restrictionAttributes.

Default Value: true

findBestSequenceBoolean

The RouteTask can help you find the most efficient path for visiting a given list of stops. This is sometimes known as the "traveling salesperson" problem. When the findBestSequence = true, the route solver is solving the Traveling Salesperson problem by computing the optimal sequence to visit the stops. As this is a combinatorial problem, we employ heuristics to solve this in a reasonable time. The heuristics do not guarantee the optimal sequence (as there is no good/fast way to prove optimality for large number of stops). It returns a solution that is close to optimal if not the optimal. The heuristic performs favorably when tested with known TSP benchmarks available in the OR research community. For these stops to be visited in the most efficient way, specify the following parameters:

routeParams.findBestSequence = true;
routeParams.preserveFirstStop = false;
routeParams.preserveLastStop = false;
routeParams.returnStops = true;

ignoreInvalidLocationsBoolean

In routes where a stop is not located on a network or a stop could not be reached, the results will differ depending on the value of this property:

• When false, the solve operation will fail if at least one of the stops specified cannot be located or reached.
• When true, as long as there are at least two valid stops that have been connected by a route, a valid result is returned. If multiple routes are processed in a single request, as long as least one route is built, a valid result is returned.

impedanceAttributeString

The network attribute name to be used as the impedance attribute in the analysis. The default is as defined in the specific routing network layer used in your RouteTask. You can specify any attribute names listed in the Service Directory under Network Dataset -> Network Attributes as Usage Type: esriNAUTCost. You can also specify a value of none to indicate that no network attributes should be used for impedance. If you specify an empty array, it will default to the default of the service.

For example, set impedanceAttribute = "Time" for the quickest route and impedanceAttribute = "Length" for shortest drive, assuming the service has those two esriNAUTCost attributes.

For more information, see Understanding the network attribute.

outputGeometryPrecisionNumber

The precision of the output geometry after generalization. If 0, no generalization of output geometry is performed. If present and positive, it represents the MaximumAllowableOffset parameter and generalization is performed according to IPolycurve.Generalize.

outputGeometryPrecisionUnitsString

The units of the output geometry precision.

Known Values: centimeters | decimal-degrees | decimeters | feet | inches | kilometers | meters | miles | millimeters | nautical-miles | points | yards

outputLinesString

The type of output lines to be generated in the result. The default is as defined in the specific routing network layer used in your RouteTask.

Known Values: none | straight | true-shape | true-shape-with-measure

Default Value: true-shape

outSpatialReferenceSpatialReference

The well-known ID of the spatial reference for the geometries returned with the analysis results. If not specified, the geometries are returned in the spatial reference of the map.

polygonBarriersDataLayer|FeatureSet

The set of polygon barriers loaded as network locations during analysis. At ArcGIS Server 10.1, an optional url property was added. Use this property to specify a REST query request to a Feature, Map or GP Service that returns a JSON feature set. The url property can be specified using DataFile. Note that either the features or url property should be specified.

polylineBarriersDataLayer|FeatureSet

The set of polyline barriers loaded as network locations during analysis. At ArcGIS Server 10.1, an optional url property was added. Use this property to specify a REST query request to a Feature, Map or GP Service that returns a JSON feature set. The url property can be specified using DataFile. Note that either the features or url property should be specified.

preserveFirstStopBoolean

If true, keeps the first stop fixed in the sequence even when findBestSequence = true. Only applicable if findBestSequence = true. The default is as defined in the specific routing network layer used in your RouteTask.

preserveLastStopBoolean

If true, keeps the last stop fixed in the sequence even when findBestSequence = true. Only applicable if findBestSequence = true. The default is as defined in the specific routing network layer used in your RouteTask.

restrictionAttributesString[]

The list of network attribute names to be used as restrictions with the analysis. The default is as defined in the specific routing network layer used in your RouteTask. Possible values are listed in the Service Directory under Network Dataset -> Network Attributes. You can also specify a value of none to indicate that no network attributes should be used as restrictions. If you specify an empty array, it will default to the default of the service.

restrictUTurnsString

Specifies how U-Turns should be handled. The default is as defined in the specific routing network layer used in your RouteTask.

Known Values: allow-backtrack | at-dead-ends-only | no-backtrack | at-dead-ends-and-intersections

returnBarriersBoolean

If true, barriers are returned with the RouteResult.

Default Value: false

returnDirectionsBoolean

If true, barriers are returned in the directions property of each RouteResult.

Default Value: false

returnPolygonBarriersBoolean

If true, polygon barriers are returned in the RouteResult.

Default Value: false

returnPolylineBarriersBoolean

If true, polyline barriers are returned in the RouteResult.

returnStopsBoolean

If true, stops are returned in the stops property of each RouteResult.

Default Value: false

returnZBoolean

If true, z values are returned in the RouteResult.

Default Value: true

startTimeDate

The time the route begins. If not specified, the default is the time specified in the route service.

startTimeIsUTCBoolean

If true, the start time will be in UTC format.

stopsDataLayer|FeatureSet

The set of stops loaded as network locations during analysis. When stops takes a FeatureSet, each feature in the FeatureSet must have a defined spatial reference. If the feature contains x and y attributes, those values are used for the stop, even if the feature includes geometry.

At ArcGIS Server 10.1 an optional url property was added. Use this property to specify a REST query request to a Feature, Map or GP Service that returns a JSON feature set. The url property can be specified using DataFile Note that either the features or url property should be specified.

useHierarchyBoolean

If true, the hierarchy attribute for the network should be used in analysis. The default is as defined in the specific routing network layer used in your RouteTask.

useTimeWindowsBoolean

A useful feature of the RouteTask is the ability to constrain stop visits to certain times of day, or "time windows". If you were required to deliver orders to four homes and each customer was available during a limited time period during the day, the route task could help you find the most efficient path for making all the deliveries.

Time windows are treated as a "soft" constraint. This means that although the solver attempts to honor time windows, if necessary, it will violate the time windows of some stops in order to reach them. Remember, the stops will be visited in the order they were added unless you set RouteParameters.findBestSequence = true.
