usage

Specifies how traffic data should be used when calculating routes.

Default Value: UseTrafficData

Traffic data usage depends on the time parameters in your route request:

• When Usage is set to UseTrafficData:

• If DepartNow is set to true, or if you specify DepartureTime or ArrivalTime, then all traffic data is considered (including live traffic and closures).

• If DepartNow, DepartureTime, and ArrivalTime are all unspecified, then only long-term closures are considered, regardless of this setting.

• When Usage is set to IgnoreTrafficData, then all traffic data is ignored regardless of the time parameters in your route request.
