Routing API Developer's Guide

Traffic-Optimized Routing

Note: This feature may be subject to premium pricing. For details, contact your HERE customer representative.

When you enable traffic-optimized routing in your requests, the Routing API uses up-to-date traffic information to calculate the route. For example, a route calculation for the current time uses live traffic information.

If the request does not include a departure time, the API assumes all current live traffic events (at the time of calculation) are valid for the entire length of the route and does not use any time-dependent information.

You can only enable traffic information for some types and transport modes. For more information, see Routing Mode Parameter Combinations.
