LocationService.Client.calculate_route_matrix(**kwargs)¶Calculates a route matrix given the following required parameters:DeparturePositionsandDestinationPositions.CalculateRouteMatrixcalculates 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,CalculateRouteMatrixwill 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 ofDeparturePositionstimes the number ofDestinationPositions.
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:
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.
CarModeOptions if traveling by Car , or TruckModeOptions if traveling by Truck .See also: AWS API Documentation

[REQUIRED]
The name of the route calculator resource that you want to use to calculate the route matrix.
Specifies route preferences when traveling by Car , such as avoiding routes that use ferries or tolls.
Requirements: TravelMode must be specified as Car .
Avoids ferries when calculating routes.
Default Value: false
Valid Values: false | true
Avoids tolls when calculating routes.
Default Value: false
Valid Values: false | true
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
[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]
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.
YYYY-MM-DDThh:mm:ss.sssZ . For example, 2020–07-2T12:15:20.000Z+01:00[REQUIRED]
The list of destination 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, [-122.339, 47.615]
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 destination 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 SnappedDestinationPositions .
Valid Values: [-180 to 180,-90 to 90]
Set the unit system to specify the distance.
Default Value: Kilometers
Specifies the mode of transport when calculating a route. Used in estimating the speed of travel and road compatibility.
The TravelMode you specify also determines how you specify route preferences:
Car use the CarModeOptions parameter.Truck use the TruckModeOptions parameter.Note
BicycleorMotorcycleare only valid when usingGrabas a data provider, and only within Southeast Asia.
Truckis not available for Grab.
For more information about using Grab as a data provider, see GrabMaps in the Amazon Location Service Developer Guide .
Default Value: Car
Specifies route preferences when traveling by Truck , such as avoiding routes that use ferries or tolls, and truck specifications to consider when choosing an optimal road.
Requirements: TravelMode must be specified as Truck .
Avoids ferries when calculating routes.
Default Value: false
Valid Values: false | true
Avoids tolls when calculating routes.
Default Value: false
Valid Values: false | true
Specifies the truck's dimension specifications including length, height, width, and unit of measurement. Used to avoid roads that can't support the truck's dimensions.
The height of the truck.
4.5 .Note
For routes calculated with a HERE resource, this value must be between 0 and 50 meters.
The length of the truck.
15.5 .Note
For routes calculated with a HERE resource, this value must be between 0 and 300 meters.
Specifies the unit of measurement for the truck dimensions.
Default Value: Meters
The width of the truck.
4.5 .Note
For routes calculated with a HERE resource, this value must be between 0 and 50 meters.
Specifies the truck's weight specifications including total weight and unit of measurement. Used to avoid roads that can't support the truck's weight.
The total weight of the truck.
3500 .The unit of measurement to use for the truck weight.
Default Value: Kilograms
