Abstract
An efficient transmission of route information, especially also in remote areas for which a terminal unit has no detailed map or location reference list, is made possible by a terminal unit, a central traffic station and a process for the transmission of route information concerning a route of a vehicle in a traffic network between a central traffic station and a terminal unit in a vehicle. The route information concerns path points lying on the route, wherein a path point is defined at every location where it is recommended that the vehicle turns off from a road. The next road following in the driving direction of the route, the location of the path point, and the driving direction after the path point are designated in each instance in route information for a path point.
