2023/01/10 - Amazon Location Service - 2 updated api methods
Changes This release adds support for two new route travel models, Bicycle and Motorcycle which can be used with Grab data source.
{'TravelMode': {'Bicycle', 'Motorcycle'}}
Calculates a route given the following required parameters: DeparturePosition and DestinationPosition . 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 the route.
Additional options include:
Specifying a departure time using either DepartureTime or DepartNow . This calculates a route 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 .
Note
If you specify walking for the travel mode and your data provider is Esri, the start and destination must be within 40km.

The fourth bbox position is the Y coordinate, or latitude of the upper northeast corner.
(float) --
{'TravelMode': {'Bicycle', 'Motorcycle'}}
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.

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 .
