RoutingPreference

AI-generated Key Takeaways

Routing preferences determine how routes are calculated, considering factors like traffic conditions.
TRAFFIC_UNAWARE provides the fastest routes without considering real-time traffic, suitable when traffic is irrelevant.
TRAFFIC_AWARE balances speed and accuracy by incorporating live traffic data with some optimizations for reduced latency.
TRAFFIC_AWARE_OPTIMAL prioritizes accuracy, calculating routes based on real-time traffic for the most precise ETAs, but may have higher latency.
The default setting is TRAFFIC_UNAWARE if no routing preference is specified using ROUTING_PREFERENCE_UNSPECIFIED.

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

Enums
`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 `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 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.
