Method and assembly for detecting traffic violations in an area with traffic lights

摘要

The method involves scanning a holding line (2) via a laser ray from a laser scanner (9), when a switching phase that is assigned to the holding line is provided as a red light phase. The ray is reflected to a vehicle, which crosses the holding line. A measuring value is stored and a camera (8) is triggered in order to create an image of the vehicle, when no correlated another measuring value is found. Data is formed from the former value, where the data identifies a concerned vehicle in a group of vehicles within the image via a position of the vehicle and indicates traffic irregularity. An independent claim is also included for an arrangement for implementing the method for detection of traffic irregularity in a traffic signal area in a driving path.
