4.1.8 Real-time traffic
Real-time traffic information can provide you with the current status of the traffic. Route
calculation can avoid road blocks or unexpected traffic jams caused by an accident.
The following data sources are available:
Traffic Message Channel (TMC):
TMC is a specific application of the FM Radio Data System (RDS) used for
broadcasting real-time traffic and weather information.
If public Traffic data is broadcast at your location, Alpine Navigation System
automatically searches the FM radio stations for TMC data, and the decoded
information is immediately used in route planning.
Note!
TMC is not a global service. It may not be available in your country or region. Ask
your local dealer for coverage details.
The application automatically takes account of the traffic events received. You do not need to
set anything in Alpine Navigation System.
When Alpine Navigation System receives traffic information that may affect your route, it
warns you that it is recalculating the route. The navigation continues with a new optimal route
considering the most up-to-date traffic conditions.
For information on traffic icons, see page 19.
To fine-tune this service, you have the following options in Traffic settings (page 74):
Set the minimum amount of time that you think is worth saving at the cost of a detour.
Instruct Alpine Navigation System to have you confirm the new planned route before it
takes effect.
Note!
If there are traffic events on the planned route that the application has not
bypassed, the
icon opens the list of significant traffic events to let you quickly
check them.
4.1.9 Intelligent navigation
With the help of intelligent navigation, the planned route can adapt to traffic and other
changes during navigation. The following sections describe these features.
4.1.9.1 Congestion detour on highways
Alpine Navigation System may offer a detour when you slow down on a highway due to a
traffic jam. The Potential congestion detour window appears and shows the length and
duration of the detour.
