5.1.8 Stored and real-time traffic information in route planning

The recommended route is not always the same between two points. Offline statistical traffic
information (historical speed information or traffic patterns) can be taken into account in the
route calculation based on the time of day and the day of week whenever suitable data exists.
In addition, real-time traffic information can help you avoid current traffic events like temporary
road closures or a traffic jam caused by an accident. Both functions are subject to data
availability.
You can display the historical traffic information on the map if you browse the map and select
this option from the More menu. A 2D map is displayed with road segments coloured by the
density of the traffic in the given period. The current information is shown when you open the
screen. Modify the day of week and the time of day to see the desired period.
