Abstract
The invention is directed to a method and an arrangement for detecting a traffic violation in a traffic light zone through rear end measurement by a FMCW radar device. For this purpose, a vehicle driving through a radar beam of a FMCW radar device, whose first outer edge beam horizontally forms an obtuse angle with the roadway edge, is measured at its front end, flank and rear end. The vehicle length is determined from the obtained measurement signals and added to the specific radial distance of the vehicle, which is determined close to a stop line through the vehicle rear, and a prediction is made based on the vehicle speed about the vehicle front driving over the stop line.
