Abstract: The invention relates to a method for recording a traffic violation in which a vehicle is involved, by detecting the violation, making a record of the violation, and searching for and reading from the record a license plate of the vehicle involved in the violation. During making of the record position information of the vehicle is herein recorded, and on the basis of this information a search is made for the license plate in only a part of the record. The recorded position information can comprise the travel direction of the vehicle, or the lane in which the vehicle is located. The record can be a picture record wherein a search for the license plate is made, on the basis of the recorded travel direction, only in a left or right-hand half or, on the basis of the recorded position information, only in a narrow strip. The invention also relates to a system for performing the method.

Abstract: The invention relates to a method for detecting the passage by a vehicle of a determined point for monitoring on a road, wherein from a remotely situated location a laser beam is transmitted continuously to the point for monitoring, reflections from the transmitted laser beam are received at the remotely situated location, and it is determined from the received reflections that the vehicle is passing the point for monitoring. The laser beam can be transmitted at right angles to the travel direction of the passing vehicle. The detection can be used to activate a red-light camera, to measure the speed of the vehicle or measure the traffic intensity, without sensors, for instance induction loops, having to be arranged in the road for this purpose. The invention further relates to a system for performing this method.

Abstract: The invention relates to a method for detecting the passage by a vehicle of a determined point for monitoring on a road, wherein from a remotely situated location a radar beam is transmitted continuously to the point for monitoring, reflections from the transmitted radar beam are received at the remotely situated location, and it is determined from the received reflections that the vehicle is passing the point for monitoring. The radar beam can herein be transmitted at an acute angle to the travel direction of the passing vehicle. The detection can be used to activate a red-light camera, to measure the speed of the vehicle or measure the traffic intensity, without sensors, for instance induction loops, having to be arranged in the road for this purpose.
