Method for determining and documenting traffic violations at a traffic light

摘要

The method involves determining a relative position of stop lines (2) provided on lanes, and deriving a relative position of an impact point (P1), lying within an observation area, from radar signals. A vertical distance from the point to one line is determined from the relative positions, and is assigned to the point. Speed is derived from the radar signals and is assigned to the point. The line is closed at a time point of passing of a vehicle based on the speed and the distance. A camera is activated when this time point lies outside a green phase of traffic lights.
