## November 10, 2015

**Features and improvements**

- The API now returns predicted travel times with traffic for times in the future, based on historical averages. Previously, the API only returned travel times in traffic for times very close to now. To receive predicted travel times with traffic, specify a departure time of "now" or some time in the future, with a travel mode of driving. You can also specify a traffic model of optimistic, pessimistic, or best guess (default), to influence the assumptions used when calculating the travel time. For details, see the [developer's guide](https://developers.google.com/maps/documentation/distance-matrix/overview.md.txt#traffic-model).
- Standard Plan customers now have access to optimal routes and travel times in traffic - these features were previously available only to Google Maps Platform Premium Plan customers.
