Abstract: A method for detecting a traffic law violation due to the allowable distance between a following vehicle and a guide vehicle being undershot, the following vehicle traveling behind the guide vehicle. At least the respective speed of the following vehicle is identified and the guide vehicle in a detection region in the surroundings of a sensor which supplies speed measurement values. A reference distance is detected and/or ascertained between the following vehicle and the guide vehicle at a reference measurement point. At least one following distance is determined between the following vehicle and the guide vehicle in the detection region using the identified speeds of the following vehicle and the guide vehicle and/or the detected reference distance. A traffic law violation is detected if the following distance in the detection region continuously falls short of a distance threshold.

The measuring device is subsequently rotated and tilted, as a result of which the camera image is rotated and shifted on the display, until the images of the roadway margins and edges running parallel thereto are in alignment at the intersection point.

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.

Abstract: A method for classifying vehicles in which an angle-resolving radar device yields measurement signals which have frequencies corresponding to a Doppler shift and which originate from measured vehicles and from which radial distances, object angles and radial velocities can be derived. The frequencies of the acquired measurement signals are stored as functions over the measurement time period, and a spectrogram is formed for every vehicle therefrom. Subsequently, the spectrograms are checked for assessment regions with maximum bandwidth of the frequency. These assessment regions are compared with assessment regions of stored spectrograms for different vehicle classes and associated with the most similar such that the measured vehicles are classified.
