routingPreference property

String? routingPreference
getter/setter pair

Specifies how to compute the routing summaries.

The server attempts to use the selected routing preference to compute the route. The traffic aware routing preference is only available for the DRIVE or TWO_WHEELER travelMode.

Optional. Possible string values are:

  • "ROUTING_PREFERENCE_UNSPECIFIED" : No routing preference specified. Default to TRAFFIC_UNAWARE.
  • "TRAFFIC_UNAWARE" : Computes routes without taking live traffic conditions into consideration. Suitable when traffic conditions don't matter or are not applicable. Using this value produces the lowest latency. Note: For TravelMode DRIVE and TWO_WHEELER, the route and duration chosen are based on road network and average time-independent traffic conditions, not current road conditions. Consequently, routes may include roads that are temporarily closed. Results for a given request may vary over time due to changes in the road network, updated average traffic conditions, and the distributed nature of the service. Results may also vary between nearly-equivalent routes at any time or frequency.
  • "TRAFFIC_AWARE" : Calculates routes taking live traffic conditions into consideration. In contrast to TRAFFIC_AWARE_OPTIMAL, some optimizations are applied to significantly reduce latency.
  • "TRAFFIC_AWARE_OPTIMAL" : Calculates the routes taking live traffic conditions into consideration, without applying most performance optimizations. Using this value produces the highest latency.
