Route guidance with traffic information
General information
In semi-dynamic route guidance systems,
detour suggestions by the navigation system
can be added manually. In dynamic route
guidance systems, they are automatically
included in the route guidance.
Semi-dynamic route guidance
With traffic information reception switched on,
semi-dynamic route guidance is active.
The system takes into account the existing traffic
information during route guidance. A message is
displayed as a function of the route, the traffic
information, and the possible alternate routes.
When there are obstructions to traffic, an alter-
nate route is provided. The difference in dis-
tance and time between the original route and
the alternate route are also displayed.
Taking an alternate route:
"Detour"
With particular hazards, e.g. objects on the road-
way, a message is displayed without a possible
alternate route.
It is also possible to take alternate routes can
also be taken if the traffic reports are accessed
via the list:
1. "Navigation"
2. "Map"
3. "Traffic Info"
4. "Detour information"
5. "Detour"
Dynamic route guidance
The route is automatically changed in the event
of traffic obstructions.
> The system will not point out traffic obstruc-
tions on the original route.
> Traffic information will continue to be
displayed on the map.
