Create a Custom Route

Stay organized with collections Save and categorize content based on your preferences.

When you are determining the best route for a ridesharing trip, the fastest route may not always be the best option. You may want to customize your route.

The Routes Preferred API lets you customize a route by specifying a route objective using the ComputeCustomRoutes method.

The ComputeCustomRoutes method can also help with route compliance by letting you minimize the difference between the route selected by the operator and the route driven.

Use both the Routes Preferred API and the Navigation SDK to realize the full benefit of route customization.

Enable the ComputeCustomRoutes method

Before you can use the ComputeCustomRoutes method in your code, you must enable it. For more information on enabling Routes Preferred API methods, see Getting Started.

Using the ComputeCustomRoutes method

The ComputeCustomRoutes 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. For more information, see System Parameters.

The field mask value is a comma-separated list of field paths. Each field path is a dot-separated list of field names that represent the message hierarchy. A field name is either the JSON object key, or the protobuf field tag name. The field path starts from the top level response message type, and is optionally followed by one or more dots, and then the next level of field name. In general, field paths are constructed in the following way:

topLevelField[.secondLevelField][.thirdLevelField][...]

A special case field mask is a wildcard “*”, which selects all root-level fields.
