5.1.5 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.

5.1.5.1 Historical traffic

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 enable this feature in Traffic
settings.

5.1.5.2 Real-time traffic information (TMC)

TMC (Traffic Message Channel) can provide you with the real-time status of
the traffic. Route calculation can avoid road blocks or unexpected traffic
jams caused by an accident.
TMC is a specific application of the FM Radio Data System (RDS) used for
broadcasting real-time traffic and weather information.
Using traffic information is enabled by default in the software.
Note! TMC is not a global service. It may not be available in your
country or region. Ask your local dealer for coverage details.
Your device contains the TMC receiver that is needed to receive Traffic
events.
If public Traffic data is broadcast at your location, the software automatically
takes into account the traffic events received. You do not need to set
anything in the program. The receiver will automatically search the FM radio
stations for TMC data, and the decoded information will immediately be
used in route planning. When your software receives traffic information that
may affect your route, the program will warn you that it is recalculating the
route, and navigation will continue with a new route that is optimal
considering the most up-to-date traffic conditions.
To fine-tune this recalculation, you can set the minimum delay that can
trigger a route recalculation, or you can instruct the software to have you
confirm the new recommended route before it takes effect. You can do
these in Traffic settings.
