ComputeRouteMatrix

ComputeRouteMatrix
`rpc ComputeRouteMatrix(ComputeRouteMatrixRequest) returns (RouteMatrixElement)` Takes in a list of origins and destinations and returns a stream containing route information for each combination of origin and destination. NOTE: This method requires that you specify a response field mask in the input. You can provide the response field mask by using the URL parameter `$fields` or `fields`, or by using the HTTP/gRPC header `X-Goog-FieldMask` (see the available URL parameters and headers. The value is a comma separated list of field paths. See this detailed documentation about how to construct the field paths. For example, in this method: Field mask of all available fields (for manual inspection): `X-Goog-FieldMask: ` Field mask of route durations, distances, element status, condition, and element indices (an example production setup): `X-Goog-FieldMask: originIndex,destinationIndex,status,condition,distanceMeters,duration` It is critical that you include `status` in your field mask as otherwise all messages will appear to be OK. Google discourages the use of the wildcard (``) response field mask, because: Selecting only the fields that you need helps our server save computation cycles, allowing us to return the result to you with a lower latency. Selecting only the fields that you need in your production job ensures stable latency performance. We might add more response fields in the future, and those new fields might require extra computation time. If you select all fields, or if you select all fields at the top level, then you might experience performance degradation because any new field we add will be automatically included in the response. Selecting only the fields that you need results in a smaller response size, and thus higher network throughput.

This setting affects the value returned in the duration field in the `RouteMatrixElement` which contains the predicted time in traffic based on historical averages. `RoutingPreference` to `TRAFFIC_AWARE_OPTIMAL` and `RouteTravelMode` to `DRIVE`. Defaults to `BEST_GUESS` if traffic is requested and `TrafficModel` is not specified.

If you don't provide this value, then the display units are inferred from the location of the first origin.
`optimize_waypoint_order`	`bool` Optional. If set to true, the service attempts to minimize the overall cost of the route by re-ordering the specified intermediate waypoints. The request fails if any of the intermediate waypoints is a `via` waypoint. Use `ComputeRoutesResponse.Routes.optimized_intermediate_waypoint_index` to find the new ordering. If `ComputeRoutesResponseroutes.optimized_intermediate_waypoint_index` is not requested in the `X-Goog-FieldMask` header, the request fails. If `optimize_waypoint_order` is set to false, `ComputeRoutesResponse.optimized_intermediate_waypoint_index` will be empty.

A reference route is a route with a different route calculation objective than the default route. For example a `FUEL_EFFICIENT` reference route calculation takes into account various parameters that would generate an optimal fuel efficient route.

This setting affects the value returned in the duration field in the `Route` and `RouteLeg` which contains the predicted time in traffic based on historical averages. `TrafficModel` is only available for requests that have set `RoutingPreference` to `TRAFFIC_AWARE_OPTIMAL` and `RouteTravelMode` to `DRIVE`.

Customers should treat this token as an opaque blob. It is not meant for reading or mutating. NOTE: `Route.route_token` is only available for requests that have set `ComputeRoutesRequest.routing_preference` to `TRAFFIC_AWARE` or `TRAFFIC_AWARE_OPTIMAL`. `Route.route_token` is not supported for requests that have Via waypoints.

RouteLeg

Contains a segment between non-via waypoints.

Fields
`distance_meters`	`int32` The travel distance of the route leg, in meters.
`duration`	`Duration` The length of time needed to navigate the leg. If the `route_preference` is set to `TRAFFIC_UNAWARE`, then this value is the same as `static_duration`. If the `route_preference` is either `TRAFFIC_AWARE` or `TRAFFIC_AWARE_OPTIMAL`, then this value is calculated taking traffic conditions into account.
`static_duration`	`Duration` The duration of travel through the leg, calculated without taking traffic conditions into consideration.
`polyline`	`Polyline` The overall polyline for this leg that includes each `step`'s polyline.
`start_location`	`Location` The start location of this leg. This location might be different from the provided `origin`. For example, when the provided `origin` is not near a road, this is a point on the road.
`end_location`	`Location` The end location of this leg. This location might be different from the provided `destination`. For example, when the provided `destination` is not near a road, this is a point on the road.
