Abstract: A method of measuring the speed of a vehicle wherein the speed and the distance of the vehicle from a radar system and/or the measuring angle of the vehicle relative to the radar axis is determined by means of a radar measurement so as to characterize or determine the vehicle lane of the vehicle by means of the distance and/or the measuring angle. Knowledge of the vehicle lane makes it possible to unequivocally identify the detected vehicle in a group of vehicles unequivocally.

Abstract: According to the present invention, a first measured data packet M1 of a first vehicle 1 at a first measuring time point tM1 and a first image data packet B1 are generated, and measured data packets MX of additional vehicles X are generated at additional measuring time points tMX, to which measured data packets duplicates of the first image data packet B1 are linked to the extent that the additional measuring time points tMX occur within a predetermined time interval ? after the first measuring time point tM1.

Abstract: A method for detecting and documenting red-light violations and/or speeding violations in which a radar beam is directed across all lanes of a roadway of interest and in which the speed and the position of a vehicle which passes through the radar beam are determined from the radar signals so as to be able to predict the probability of a red-light violation from the speed and the determined distance of the measured vehicle from a stop line and to trigger the recording of images of the violating vehicle at predetermined distances from the stop line.
