The DriveTimeTask class requests creating driving distance or driving time-based trade/service areas around origin points.

Drive Time trade/service areas use street networks and approximate driving times based on attributes associated with the traversed streets around the Drive Time area origins. These area origins are point features such as businesses, store fronts, organizations, agencies, hospitals, or service centers that may serve the area or region, and may have competitors or affiliates nearby.

The result of this task is a TaskResultOutput object, which is compatible with ArcGIS Server's mapping APIs. Optional analysis, which can be requested simultaneously, includes the creation a map image for the resulting trade/service areas and the creation of Summary Reports based on the resulting trade/service areas.

The Drive Time analysis using the donut parameter option creates output trade/service areas that are in bands instead of concentric overlapping areas. For example, if three radii are entered with values of one, three, and five minutes, three output bands would be created with 0-1, 1–3, and 3–5 minute Drive Time trade areas instead of 0-1, 0-3, and 0-5 minute Drive Time trade areas. This will result in the creation of non-overlapping trade/service areas that will have significantly different results in subsequent analysis such as with Summary Reports.

Some applications of Drive Time include the following:

In order to compensate for traffic patterns in the analysis task, adjust driving distances or times (the radii parameter) accordingly. For example, if the analysis needs to be performed for a time of day when traffic patterns are heavy (i.e. rush hour) and the drive time takes twice as long, then enter driving distances or times that are half as long to reflect this pattern.

The Drive Time analysis task differs significantly from Simple Rings-based trade/service areas, which define these areas based on straight-line ("as the crow flies") distances from the origin points.

Property detail
lastResultproperty
lastResult:TaskResultOutput  [read-only]

The last result of executing the DriveTime task.

Implementation
    public function get lastResult():TaskResultOutput
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 BAOnlineClient type instance with other tasks (the urlOrClient parameter has the BAOnlineClient type) or as a standalone task encapsulating its own client.

The base URL to the Business Analyst Online Web Services looks as follows:

http://{host}:{port}

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

If urlOrClient is null, the "http://baoapi.esri.com" value is assigned as the base URL.

Parameters
urlOrClient:Object (default = null) — A variable containing either Business Analyst Online HTTP Service base URL string or an instance of the BAOnlineClient 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 DriveTime task to the Business Analyst Online 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.
Constant detail

public static const name:String = "report/DriveTime"
