calculate_route_matrix#

LocationService.Client.calculate_route_matrix(**kwargs)#

Calculates a route matrix given the following required parameters: DeparturePositions and DestinationPositions. CalculateRouteMatrix calculates routes and returns the travel time and travel distance from each departure position to each destination position in the request. For example, given departure positions A and B, and destination positions X and Y, CalculateRouteMatrix will return time and distance for routes from A to X, A to Y, B to X, and B to Y (in that order). The number of results returned (and routes calculated) will be the number of DeparturePositions times the number of DestinationPositions.

Note

Your account is charged for each route calculated, not the number of requests.

Requires that you first create a route calculator resource.

By default, a request that doesn’t specify a departure time uses the best time of day to travel with the best traffic conditions when calculating routes.

Additional options include:

  • Specifying a departure time using either DepartureTime or DepartNow. This calculates routes based on predictive traffic data at the given time.

Note

You can’t specify both DepartureTime and DepartNow in a single request. Specifying both parameters returns a validation error.

  • Specifying a travel mode using TravelMode sets the transportation mode used to calculate the routes. This also lets you specify additional route preferences in CarModeOptions if traveling by Car, or TruckModeOptions if traveling by Truck.

Parameters:

  • CalculatorName (string) –

    [REQUIRED]

    The name of the route calculator resource that you want to use to calculate the route matrix.

  • CarModeOptions (dict) –

    Specifies route preferences when traveling by Car, such as avoiding routes that use ferries or tolls.

    Requirements: TravelMode must be specified as Car.

    • AvoidFerries (boolean) –

      Avoids ferries when calculating routes.

      Default Value: false

      Valid Values: false | true

    • AvoidTolls (boolean) –

      Avoids tolls when calculating routes.

      Default Value: false

      Valid Values: false | true

  • DepartNow (boolean) –

    Sets the time of departure as the current time. Uses the current time to calculate the route matrix. You can’t set both DepartureTime and DepartNow. If neither is set, the best time of day to travel with the best traffic conditions is used to calculate the route matrix.

    Default Value: false

    Valid Values: false | true

  • DeparturePositions (list) –

    [REQUIRED]

    The list of departure (origin) positions for the route matrix. An array of points, each of which is itself a 2-value array defined in WGS 84 format: [longitude, latitude]. For example, [-123.115, 49.285].

    Warning

    Depending on the data provider selected in the route calculator resource there may be additional restrictions on the inputs you can choose. See Position restrictions in the Amazon Location Service Developer Guide.

    Note

    For route calculators that use Esri as the data provider, if you specify a departure that’s not located on a road, Amazon Location moves the position to the nearest road. The snapped value is available in the result in SnappedDeparturePositions.

    Valid Values: [-180 to 180,-90 to 90]

    • (list) –

      • (float) –

  • DepartureTime (datetime) –

    Specifies the desired time of departure. Uses the given time to calculate the route matrix. You can’t set both DepartureTime and DepartNow. If neither is set, the best time of day to travel with the best traffic conditions is used to calculate the route matrix.

    Note

    Setting a departure time in the past returns a 400 ValidationException error.

    • In ISO 8601 format: YYYY-MM-DDThh:mm:ss.sssZ. For example, 2020–07-2T12:15:20.000Z+01:00
