Abstract
A traffic-dependently controllable signaling system utilizing the lengths of the time intervals between two successive vehicles for terminating the green light duration for the involved flow of traffic, in which each time interval is compared with a first, larger theoretical time limit value. If the first theoretical time limit value is reached, the green light signal for such traffic flow is terminated. In addition, all time gaps are compared with a second smaller theoretical time limit value and if this second theoretical time limit value is exceeded by two successive time intervals or at least two of a group of time intervals, the green light signal for the particular flow of traffic is likewise terminated.
