Abstract (en)
[origin: WO8701847A1] In order to ensure the photographic monitoring of cross-roads a camera (26 or 28) is provided which covers an intersection (10). An initial sensor (22) responses when a vehicle (30 or 32) goes beyond a halt line during the stop phase of the traffic lights (16), in which case an initial photograph is taken by the camera (26) or (28). A second sensor (24) is arranged directly ahead, behind the first sensor (22) in the danger area of the intersection (10) and in an optimum photographic position in relation to the camera (26 or 28) and when this sensor is passed a second photograph is triggered. As a result, the vehicle (30 or 32) is photographed whatever its speed and always in an optimum photographic position.
