The Drive Time task creates trade areas based on the driving time or driving distance around store features.

Equal competition market areas do not adjust for the way people actually travel on the ground. Equal competition market areas are based on as the crow flies distances, while people in the real world have to use roads and streets. A two mile trip might take five minutes on one road network and 15 minutes on another.

Using this task, you can generate the drive time areas that use actual street networks and approximated driving times.

Pizza delivery provides a good case example for the use of drive time polygons. A company may want to limit deliveries to a total of 15 minutes. This means that the delivery radius of each store would be restricted to a 6 minute drive time (six minutes to the delivery point, three minutes at the delivery site, and six minutes to return, for a total of 15 minutes).

Overlap can occur. Some store chains solve this problem by using equal competition areas where drive time overlap occurs, to make each service zone unique and using the drive times at the edge of the built up urban areas to restrict delivery distances and times.

The result of this task is a TaskResultOutput object, which is compatible with ArcGIS Server's mapping APIs. FeatureSet, MapImage, and an array of ReportInfo objects can be returned in it depending on task output options requested. Additionally, the output analysis layer and/or report can be stored to the Business Analyst Server repository.

Implementation

Constructor Detail
DriveTimeTask()Constructor
public function DriveTimeTask(urlOrClient:Object = null)

Creates a new instance of the DriveTimeTask class.

A new task can be constructed in two ways: as a task sharing a BAServerClient type instance with other tasks (the urlOrClient parameter has the BAServerClient type) or as a standalone task encapsulating its own client.

The base URL to the Business Analyst Server HTTP Service looks as follows:

http://{host}:{port}/ArcGIS/baserver/REST/services/DefaultMap/BAServer

The {host} and {port} parameters in this URL should be substituted with valid Business Analyst Server host name and port, respectively.

Parameters
urlOrClient:Object (default = null) — A variable containing either Business Analyst Server HTTP Service base URL string or an instance of the BAServerClient class.

Method Detail
createCommand()method
public function createCommand(parameters:DriveTimeParameters, commandName:String = null):BACommand

Creates a new command encapsulating this task and the given parameters.

Parameters

parameters:DriveTimeParameters — Parameters of a task to be executed.
 
commandName:String (default = null) — Command name.

Returns
BACommand — A new command.
execute()method 
public function execute(parameters:DriveTimeParameters, responder:IResponder = null):AsyncToken

Sends a request for executing a Drive Time task to the Business Analyst Server HTTP (REST) Service.

A response can be received in two ways—in an optional responder object passed in parameters of this method and/or in listeners of fault and taskCompleted events registered for this task.

The responder is notified first when a response is received and parsed. Its fault method receives a parameter of the FaultEvent type and its result method receives a parameter of the BATaskCompletedEvent type whose result property contains the result object. After that the received event is dispatched to listeners of this task.

If a response is succesfully received and parsed, the result is assigned to the lastResult property of this task.

Parameters

parameters:DriveTimeParameters — Parameters of the task.
 
responder:IResponder (default = null) — A responder to call on result or fault.

Returns
AsyncToken — Asynch token associated with the response.
