Abstract

In a method for automatically monitoring traffic, traffic data are recorded at several measuring points of the traffic network. The time-dependent positions of the upstream back-up flank and of the downstream back-up flank are estimated continuously according to characteristic relationships which take into account the flow and the density of the traffic in the back-up, the point in time at which the upstream back-up flank passes a respective first measuring point, the point in time at which the downstream back-up flank passes this measuring point as well as the flow and the average vehicle speed at this first as well as at a second measuring point which is situated upstream of the upstream back-up flank.
