The recommended, calculated at the headquarters Route Route information concerned are coded efficiently transmitted in a vehicle to a terminal. In this case, be defined along the calculated route reference points in the central route, the required actions of the driver, in particular the choice of a direction of travel, describe. In particular route reference points are defined on descents, junctions or branches. On

Wegleitpunkt is thus defined where a driver can continue on a road in different streets, so where a turn of a road is possible. The transferred to a Wegleitpunkt on the recommended route from the traffic control center to the terminal route information includes the location of the Wegleitpunktes whose intersection geometry determining Wegleitpunkt-

Geometric data and the route through the Wegleitpunkt defining transition data. The location of the Wegleitpunktes can be specified in particular in the form of geographic coordinates of Wegleitpunktes. The data format of route information is defined the same in the terminal and in the traffic control center. The locus may for example be transmitted in form of rounded to a certain length geographical 'longitude, latitude.

The transition data defines appropriate the entrance road of the vehicle in the Wegleitpunkt to enable efficient information of the user of the terminal in the vehicle via the planned route. It should also by the

Transmitting an exit road from a Wegleitpunkt appropriate. The entrance road is the road or the road section from which a vehicle enters an intersection or traveling towards his Abzweigemöglichkeit. The exit road is the one street of which is to further drive a vehicle in accordance with the recommended route from an intersection or turn possibility of, so that road for which he should a driver of a vehicle at an intersection, junction or the like decide '.

Conveniently, at least the intersection geometry of the next waypoint on the recommended route is transmitted. Technically transmission, the transmission route information on several, lying in the direction of the route ahead of the vehicle Wegleitpunkten meaningful.

The Wegleitpunkt geometry data may include angle to each of a street or a street segment on Wegleitpunkt particular. In each case, the angles between the individual roads of an intersection, exit, etc. can be given. Also, each of the angles can be specified every street etc. at a Wegleitpunkt compared to the current direction of travel of the vehicle or with respect to a compass direction. When transmitting each an angle relative to a fixed direction, for example north, the angle is simply determined from a digital map, table, etc. in the traffic control center.

The intersection geometry of a Wegleitpunktes can be represented visually in the central office. In optical representation from the terminal on a display, etc. may in particular by the recommended route certain access road and / or

Exit road are displayed highlighted by brightness, beam thickness, color, etc. to at least one Wegleitpunkt; possibly can be visualized also deviating from a recommended route an access road and / or exit road with a possibly different emphasis.

A false trip detection, so the detection of an actual route of the vehicle, which deviates from the recommended route may be accomplished by comparison of transmitted Wegleitpunkt geometry data and / or Wegleitpunkt location data with one or more positions of the terminal of the vehicle. This can, for example, a GPS measurement in the terminal for determining the location and / or a repeated

GPS message used in the terminal for direction determination.
