Device for controlling traffic flow near junction, especially with traffic lights, evaluates fan beam incident point profile, associates with individual spatially related incident point object groups

摘要

The device has at least one sensor device that detects vehicles near the junction. The sensor device has a transmitter that radiates a circulating light pulse in the form of a radiating fan and a receiver that detects the point of incidence of the light pulse. The profile of the point of incidence is evaluated and associated with individual spatially related groups of incident point objects. The device has at least one sensor device (18) that detects vehicles near the junction. The sensor device has a transmitter that radiates a circulating light pulse in the form of a radiating fan (19) and a receiver that detects the point of incidence of the light pulse, whereby the sensor device is arranged so that the fan generated by the transmitter scans the junction area in a plane parallel to and slightly above it. The profile of the point of incidence is evaluated and associated with individual spatially related groups of incident point objects.
