Abstract
A suitable selection of information sent by a central traffic station with respect to its relevance for a route of a vehicle with a terminal unit through the traffic network is made possible by a terminal unit and by a process for the selection of traffic information which is relevant to a route of a vehicle in a traffic network, which vehicle has a terminal unit, and which is transmitted by a central station. The route is determined in the form of path points between a starting point and a destination in the traffic network. A zone is defined for the selection of relevant traffic information between two path points. Traffic information concerning a location in the zone is selected as relevant, while traffic information concerning a location outside of the zone is defined as irrelevant.
