5.1.9 Traffic information in route planning

The function is subject to data availability. 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.
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.

5.1.9.1 Historical traffic

The function is subject to data availability. If statistical traffic information is stored
with the map data, the software can take them into account when planning a route.
In normal cases, these statistics help you avoid usual traffic jams on the given
day of week in the given hour but in some cases like on public holidays that fall on
normal weekdays, they can be misleading.
You can display statistical traffic information on the map if you browse the map
and select this option from the More menu.
