OVERTAKING BEHAVIOUR AND QUALITY ON TWO-LANE ORDINARY ROADS WITH ONCOMING TRAFFIC
UEBERHOLVERHALTEN UND QUALITAET AUF ZWEISPURIGEN LANDSTRASSEN MIT GEGENVERKEHR
The assessment of the quality of the traffic flow on two-lane roads with oncoming traffic is, in addition to characteristic values on the stream of vehicles, increasingly based on characteristic values of models of the queuing theory. These mathematical procedures permit, on the basis of suitable model parameters, a theoretical description of the traffic flow as a waiting system. The reported study had the objective of ascertaining, on the basis of empirical methods, characteristic values of systems of this kind, which generally depend on the behavior of road users. After the selection of suitable road sections the possibilities of overtaking offered to drivers who had to wait and their decisions were recorded by means of a measuring vehicle. In terms of the queuing theory, the mesauing vehicle was to be regarded as mobile service point recording the times of arrival, service and waiting in the moving system. The results confirm the assumption that there is a correlation between the speed of the vehicle to be overtaken and the ascertained characteristic values. It must be assumed that with increasing speed larger relative intervals between oncoming vehicles will be required for carrying out an overtaking maneuver.
