Abstract (en)
[origin: US4350970A] In a method for traffic determination, a routing and information system for individual motor vehicle traffic is used, in which by way of stationary routing station poles, route information and local information are transmitted to the passing vehicles. For the determination of the traffic situation, the traveling times between two routing station poles are measured in individual vehicles with timing units. These traveling times are transmitted, together with the local information of the first routing station pole passed by a vehicle, to the second routing station pole and are considered in determining new route recommendations.
