Abstract: With a traffic monitoring device for photographic recording of vehicles exceeding a predetermined speed, the speed of the approaching traffic is measured substantially against the travelling direction. The vehicles (12) are photographed frontally when they exceed the predetermined speed. Two speed measurements are effected: A first measuring value is obtained in a relatively short part of the available measuring section (22) on the entrance side and serves to release a camera (18). A second measuring value evaluates all speed measuring values occuring in the measuring section (22), in which the vehicle (12) is detected by the radar beam (20). This second measuring value is recorded.
