A set of values that specify factors to take into consideration when calculating the route.

---|---|
ROUTING_PREFERENCE_UNSPECIFIED |
No routing preference specified. Default to TRAFFIC_AWARE . |
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 RouteTravelMode 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 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 traffic conditions into consideration, without applying most performance optimizations. Using this value produces the highest latency. |
