The invention relates to the field of road traffic control and in particular to traffic control at an intersection with the aid of a traffic light. The method for vehicle traffic control at an intersection comprises traffic control with the aid of a traffic light, wherein vehicles approaching the intersection at a distance which is closer than a preset limit are detected and identified, for which purpose units for identifying vehicles are pre-installed on said vehicles, units for detecting vehicles are installed at predetermined locations for the far and near limits of the approach to the traffic light, these units for detecting vehicles are used to probe, using a radio signal, the space at the location at which said units are installed, the units for identifying vehicles entering the radio-probing area are used to produce response signals containing a code word with identification data for a corresponding vehicle, and these response signals are detected, received and decoded, with the aid of the detection units, while the length of the "go" signal is set to be equal at least to the time taken for the vehicles, from among those crossing the far limit of the approach in a given direction while the "stop" signal is active, as well as the preceding "go" signal, to complete crossing of the near limit of the approach. |
