Abstract

A method for determining the traffic state in a traffic network with effective bottlenecks with a classification at least into the “freely flowing traffic”, “synchronized traffic” and “moving widespread congestion” state phases and into patterns of dense traffic upstream of effective bottlenecks. FCD traffic data which includes information relating to the location and the speed of the vehicle is recorded at time intervals for a respective route section, and by reference to the information it is determined whether an effective bottleneck is present. If this is the case, from the current FCD traffic data, a pattern of dense traffic, which fits it, is continuously determined as a currently present pattern of dense traffic.
