Calculate toll fees for a route

When you are computing a route or a route matrix, you might want to take into consideration any toll fees on the route. For select cities, you can compute the estimated toll fee for a route in the appropriate currency.

To get tolls for a route matrix, see Calculate tolls fees for a route matrix.

For the list of supported toll locations, see the reference for TollPass

How tolls are calculated

The Routes API calculates the estimated toll fee, taking into consideration any toll price discounts or passes available to the driver or vehicle, and the most convenient payment methods. If there is no available toll price for a given route, the Routes API indicates the existence of a toll with an unknown fee.

In order to accurately calculate toll information, the Routes API gives you the option of specifying:

• The emission type of the vehicle used for the route (VehicleEmissionType). If no emission type is provided, the toll for a gasoline-fueled vehicle is returned.
• Any toll passes for the driver or vehicle that may apply (TollPass). If no toll passes are specified, the API returns the cash price.
• avoidTolls as a RouteModifier to avoid toll roads.

Calculating tolls when using a toll pass

In some regions, a driver or vehicle with a toll pass pays a different toll than those who don't have a pass. For example, if you have a Good To Go! toll pass in Seattle, WA, US, you pay a lower toll than if you don't have a pass.

Some regions, such as Indonesia, have roads that require a toll pass. If a toll pass is not specified for a route where a toll pass is required, no price is returned.

If you specify a toll as part of the request, the API tries to return the pass price:

• If you specify an invalid toll pass, the pass is ignored.

• You can specify multiple toll passes as an array. The API attempts to calculate the pass price for the route for each pass.

Calculate toll fees for a route

The following example uses the computeRoutes method to return toll information with an estimated price when a toll pass is used. In this example, you:

• Set the extraComputations array field to TOLLS to enable the calculation of toll information.

• Specify the vehicle type and the toll pass type by using the routeModifiers field of the request. The toll price returned is based on the pricing used by the specified vehicle type and pass. If more than one pass is specified, the least expensive pricing is returned.

• Use the response field mask to configure the method to return toll information in the response. In this example, the request included the following properties in the response field mask:

  • routes.travelAdvisory.tollInfo field to return information for the entire route.

  • routes.legs.travelAdvisory.tollInfo to return information for each leg.

Response containing toll information

The response contains information on tolls in a TollInfo (REST) or TollInfo (gRPC) object. In this example, you return toll information for the entire route and for each leg of the route.
