Abstract
A method for taking into account supplementary traffic information for operating an onboard travel control system of a motor vehicle, containing an internal digital road map, by transferring a point of origin and destination to a central computer and transmitting, to the onboard travel control system of the motor vehicle, a route plan drawn up in the central computer, taking into account the supplementary traffic information is achieved, at low data transmission rates and maintaining short transmission times, by providing the internal digital road map of the onboard travel control system with information about location codes; by transmitting the route plan by specifying route segments that are defined by the location codes and lie between the point of origin and the destination; and by modifying the transmitted route segments in the internal digital road map of the travel control system so that they are taken into account as a higher priority than non-transmitted route segments during the subsequent route selection carried out in the onboard travel control system.
