Abstract
A method and a device for vehicle guidance as a function of the traffic situation is provided, during which vehicle guidance the traffic situation data are evaluated in a control center which has a computer. The control center computer determines the optimum route as a function of starting data, the traffic situation data and stored road network data in the form of sequences of intermediate destinations such that a vehicle-end navigation device is capable of reproducing successive sections of the optimum route and issuing the associated guidance instructions by using a traffic situation-independent route search method. This system permits a traffic situation-dependent vehicle guidance in which the more costly route optimization tasks are performed by the control center computer. The vehicle-end navigation computer only has to carry out traffic situation-independent route finding tasks.
