originsLayer

(Required)

The starting point or points of the routes to be generated.

Syntax: As described in detail in the Feature input topic, this parameter can be one of the following:

• A URL to a feature service layer with an optional filter to select specific features
• A feature collection

Examples:

• {"url": <feature service layer url>, "filter": <where clause>}
• {"layerDefinition": {}, "featureSet": {}, "filter": <where clause>}

destinationsLayer

(Required)

Syntax: As described in detail in the Feature input topic, this parameter can be one of the following:

• A URL to a feature service layer with an optional filter to select specific features
• A feature collection

Examples:

• {"url": <feature service layer url>, "filter": <where clause>}
• {"layerDefinition": {}, "featureSet": {}, "filter": <where clause>}

measurementType

(Required)

The origins and destinations can be connected by measuring straight-line distance, or by measuring travel time or travel distance along a street network using various modes of transportation known as travel modes.

Valid values are a string, StraightLine, which indicates Euclidean distance will be used as the distance measure, or a JSON object representing settings for a travel mode.

Travel modes are managed in ArcGIS Online and can be configured by the administrator of your organization to better reflect your organization's workflows. 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, run the GetTravelModes operation from the Utilities service.

When using a travel mode for the measurementType parameter, use a JSON object representing travel mode settings for the value. When you use the GetTravelModes operation from the Utilities service, the result is a string representing the travel mode JSON. You must convert this string to a valid JSON object using the API and pass the JSON object as the value for the measurementType parameter.

For example, the following is a string representing the Walking Time travel mode as returned by the GetTravelModes operation:

"{\"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\"}"

Convert the value above to a valid JSON object and pass it as the value for the measurementType parameter.

}

originsLayerRouteIDField

Specify the field in the origins layer containing the IDs that pair origins with destinations.

• The ID values must uniquely identify points in the origins layer.

• Each ID value must also correspond with exactly one route ID value in the destinations layer. Route IDs that match across the layers create origin-destination pairs, which the tool connects together.

• Specifying originsLayerRouteIDField is optional when there is exactly one point feature in the origins or destinations layer. The tool will connect all origins to the one destination or the one origin to all destinations, depending on which layer contains one point.

destinationsLayerRouteIDField

Specify the field in the destinations layer containing the IDs that pair origins with destinations.

• The ID values must uniquely identify points in the destinations layer.

• Each ID value must also correspond with exactly one route ID value in the origins layer. Route IDs that match across the layers create origin-destination pairs, which the tool connects together.

• Specifying destinationsLayerRouteIDField is optional when there is exactly one point feature in the origins or destinations layer. The tool will connect all origins to the one destination or the one origin to all destinations, depending on which layer contains one point.

timeOfDay

Specify whether travel times should consider traffic conditions. To use traffic in the analysis, set measurementType to a travel mode object whose impedanceAttributeName property is set to TravelTime and assign a value to timeOfDay. (A travel mode with other impedanceAttributeName values don't support traffic.) The timeOfDay value represents the time at which travel begins, or departs, from the origin points. The time is specified as Unix time (milliseconds since midnight, January 1 1970).

The service supports two kinds of traffic: typical and live. Typical traffic references travel speeds that are made up of historical averages for each five-minute interval spanning a week. Live traffic retrieves speeds from a traffic feed that processes phone probe records, sensors, and other data sources to record actual travel speeds and predict speeds for the near future.

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, and 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., 4 January 1990; and convert to milliseconds (631458180000).

Live Traffic:

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

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.

Syntax: The number of milliseconds since the Unix epoch (January 1, 1970).

Examples:

• "timeOfDay": 631458180000 // 13:03, 4 January 1990. Typical traffic on Thursdays at 1:03 p.m.
• "timeOfDay": 631731600000 // 17:00, 7 January 1990. Typical traffic on Sundays at 5:00 p.m.
• "timeOfDay": 1413964800000 // 8:00, 22 October 2014. If the current time is between 8:00 p.m., 21 Oct. 2014 and 8:00 p.m., 22 Oct. 2014, live traffic speeds are referenced in the analysis; otherwise, typical traffic speeds are referenced.
• "timeOfDay": 1426674000000 // 10:20, 18 March 2015. If the current time is between 10:20 p.m., 17 Mar. 2015 and 10:20 p.m., 18 Mar. 2015, live traffic speeds are referenced in the analysis; otherwise, typical traffic speeds are referenced.

timeZoneForTimeOfDay

Specify the time zone or zones of the timeOfDay parameter. There are two options: GeoLocal (default) and UTC.

GeoLocal:

The timeOfDay value refers to the time zone in which the originsLayer points are located.

GeoLocal Illustration: Setting timeOfDay to 9:00 a.m., 4 January 1990 (631443600000 milliseconds); timeZoneForTimeOfDay to GeoLocal; and submitting a valid request causes the drive times for origins in the Eastern Time Zone to start at 9:00 a.m. (2:00 p.m. UTC).

UTC:

The timeOfDay value refers to Coordinated Universal Time (UTC).

UTC Illustration: Setting timeOfDay to 9:00 a.m., 4 January 1990 (631443600000 milliseconds) and timeZoneForTimeOfDay to UTC, the start time for origins in the Eastern Time Zone is 4:00 a.m. Eastern Time (9:00 a.m. UTC).

Values: GeoLocal | UTC

includeRouteLayers

When includeRouteLayers is set to true, each route from the result is also saved as a route layer item. A route layer includes all the information for a particular route, such as the stops assigned to the route as well as the travel directions. Creating route layers is useful if you want to share individual routes with other members in your organization. The route layers use the output feature service name provided in the outputName parameter as a prefix, and the route name generated as part of the analysis is added to create a unique name for each route layer.

pointBarrierLayer

Specify one or more point features that act as temporary restrictions (barriers) when traveling on the underlying streets.

A point barrier can model a fallen tree, an accident, a downed electrical line, or anything that completely blocks traffic at a specific position along the street. Travel is permitted on the street but not through the barrier.

Syntax: As described in detail in the Feature input topic, this parameter can be one of the following:

• A URL to a feature service layer with an optional filter to select specific features
• A feature collection

Examples:

• {"url": <feature service layer url>, "filter": <where clause>}
• {"layerDefinition": {}, "featureSet": {}, "filter": <where clause>}

lineBarrierLayer

Specify one or more line features that prohibit travel anywhere the lines intersect the streets.

A line barrier prohibits travel anywhere the barrier intersects the streets. For example, a parade or protest that blocks traffic across several street segments can be modeled with a line barrier.

Syntax: As described in detail in the Feature input topic, this parameter can be one of the following:

• A URL to a feature service layer with an optional filter to select specific features
• A feature collection

Examples:

• {"url": <feature service layer url>, "filter": <where clause>}
• {"layerDefinition": {}, "featureSet": {}, "filter": <where clause>}

polygonBarrierLayer

Specify one or more polygon features that completely restrict travel on the streets intersected by the polygons.

One use of this type of barrier is to model floods covering areas of the street network and making road travel there impossible.

Syntax: As described in detail in the Feature input topic, this parameter can be one of the following:

• A URL to a feature service layer with an optional filter to select specific features
• A feature collection

Examples:

• {"url": <feature service layer url>, "filter": <where clause>}
• {"layerDefinition": {}, "featureSet": {}, "filter": <where clause>}

routeShape

Specify the shape of the route that connects each origin to it's destination when using a travel mode.

Values: FollowStreets | StraightLine

Default: FollowStreets

• FollowStreets: The shape is based on the underlying street network. This option is best when you want to generate the routes between origins and destinations. This is the default value when using a travel mode.
• StraightLine: The shape is a straight line connecting the origin-destination pair. This option is best when you want to generate spider diagrams or desire lines (for example, to show which stores customers are visiting). This is the default value when not using a travel mode.

The best route between an origin and it's matched destination is always calculated based on the travel mode, regardless of which route shape is chosen.

outputName

If provided, the task will create a feature service of the results. You define the name of the service. If an outputName value is not provided, the task will return a feature collection.

{
  "serviceProperties": {
    "name": "<service name>"
  }
}

{

  "itemProperties": {
			"itemId": "<itemID of the existing feature service>",
			"overwrite": True
	}
}

{
"serviceProperties": {
    "name": "<existing service name>"
  },
"itemProperties": {
				"itemId": "<itemID of the existing feature service>",
				"overwrite": True
	}
}

context

Context contains additional settings that affect task execution. For Connect Origins to Destinations, there are two settings.

1. Extent (extent)—a bounding box that defines the analysis area. Only those features in the originsLayer and destinationsLayer that intersect the bounding box will be analyzed.

2. Output spatial reference (outSR)

   • If the output is a feature service, the spatial reference will be the same as originsLayer. Setting outSR for feature services has no effect.
   • If the output is a feature collection, the features will be in the spatial reference of the outSRvalue or the spatial reference of originsLayer when outSR is not specified.

{
"extent" : {extent}
"outSR" : {spatial reference}
}

f

The response format. The default response format is html.

Values: html | json
