ABSTRACT:
A method of and an arrangement for controlling a traffic control system comprising at least two measuring points located at a mutual distance along a traffic lane. It is determined whether the speed of a vehicle detected at one of the measuring points is less than a predetermined part of a running weighted average speed of vehicles detected in at least both measuring points. This has, inter alia, the disadvantage that a number of alarm signals are unnecessarily generated, which does not promote safety on the road. To obviate this it is determined at a measuring point, located downstream in the traffic direction, of the two above-mentioned measuring points, whether or not the speed of a vehicle detected there is less than a predetermined part of a running weighted average speed, which is exclusively determined from the vehicle speed detected at the upstream measuring point of these two measuring points.
