Method for the automatic coordination of an independent intersection traffic light control device with one or more neighbouring intersections.

摘要

Method for the automatic coordination of an independent intersection traffic light control device with neighbouring intersections. The traffic flowing therefrom is recorded and analysed, where, for a predefinable measuring time period (MZ) with a number (I) of time intervals (ti), the number (Z) of vehicles per time interval is determined and stored. The measuring time period is divided up into test cycles (Zy) with equal-length cycle time (TZ). Within the test cycles, the number of vehicles is added up for each associated time interval. Such a mapping of the total measuring time period onto a test cycle enables mean value and variance formation for these numbers. Mappings and variance calculations of this type are carried out for further test cycles with respective different cycle times. Since the size of the variance provides a measure of the cyclic characteristic of the traffic flow, an existing vehicle cycle and its cycle time are determined from the calculated variances for the coordinated control of the traffic lights.
