Dynamic route planning
With the help of the TMC traffic information, the dynamic route planning integrates
the entire traffic situation in an adjustable radius (traffic horizon) around the current
position into its calculation of the route. If a traffic obstruction (e.g. stationary traffic)
is reported via TMC for the planned route, the navigation system will analyse the infor-
mation and calculate the anticipated delay.
If there is a traffic problem on the planned route, you will be informed of this by the
navigation system and may decide whether the system should take a detour by changing
the route in order to avoid the segment concerned or whether it would be more sensi-
ble just to drive through the problem.
The basis for the possible delay due to a traffic obstruction and calculated by the navi-
gation system is data that the system receives via the currently selected TMC station.
The actual delay may deviate from the calculation.
If you have activated the automatic mode, the system automatically plans the route so
that you are guided extensively around the road obstructions without the system issuing
a message.
During guidance, the system checks continuously on the basis of the traffic information
whether there is a better route for route guidance and a new route is sometimes calcu-
lated, for example, if a traffic jam has disappeared.
Depending on the setting in the dynamic route planning, there are two different types
of detour:
■
Extensive detour (with activated dynamic route planning only)
As soon as the navigation system has received information via RDS-TMC about one or
more traffic obstructions that would mean a relatively long delay for navigation to
your destination, the system offers you well in advance the option of detouring the
traffic obstructions extensively.
✎
The criteria that influence a new planning of the route (re-routing level, traffic horizon
and entire delay) can be set under “Settings –> Dynamic route”.
✎
It is possible to replan the route manually at any time in the light of the current traffic
situation with the “Plan new route” menu item on the guidance screen.
■
Extensive detour (with deactivated dynamic route planning only)
With the local detour, it is possible to bypass the next traffic obstruction ahead which
is announced by TMC.
As soon as you have arrived up to approx. 50 km from the road obstruction, you will
receive an appropriate message.
✎
With the “Local detour” menu item on the guidance screen, you can bypass the
imminent road obstruction if required.
