Default Trip Costs

Many of the Routing APIs return estimated trip costs for each leg of a route (stop to stop) as well as for the entire trip. The costs are calculated using:

  • Toll costs, which are based on toll data in the Trimble Maps database and the route path generated by the API.

  • Other trip costs, which include fuel costs, distance-based costs, time-based costs, and stop costs. These are based on parameter values that you assign, and the route path generated by the API. If you don’t assign values, default values are used. The table below includes the current defaults (dataVersion: Current). These values change with every new version release of PC*Miler.
