4.1.8 Stored and online 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 (TMC) can help you avoid cur-
rent traffic events like temporary road closures or a traffic jam caused by an accident. Both functions are subject to
data availability.
Smart Routes with stored statistical traffic information
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 disable this Smart
Route feature in Traffic settings (page 76).
Real-time traffic information (TMC)
Unlike statistical traffic information, 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.
The software has no connection to the GPS receiver: GPS
navigation is not pos-
sible.
Devices with a built-in GPS receiver are permanently connected.
On such devices, the icon does not appear in normal circumstanc-
es.
The software is connected to the GPS receiver, but the signal
is too weak and the receiver cannot determine the GPS position.
GPS navigation is not possible.
Only a few satellites are received. Position information is avail-
able, but elevation (altitude) cannot be calculated.
GPS navigation is possible, but the position error may
be significant.
Altitude information is available, the position is a 3D posi-
tion. GPS navigation is possible.
