Automated detection of all kinds of violations at a street intersection using real time individual vehicle tracking

In this paper we introduce a system that detects all kinds of violations at a street intersection such as red light running, speed violation, stop line violation and lane violation by tracking individual vehicles. Two cameras are used for detecting violations. One is an analog camera for real-time tracking and the other is a digital camera for license plate reading. This system is connected to the traffic signal system controller and monitors the red, arrow, yellow and green phases of an approach. Two loops in the road are used to detect vehicle approach and speed. The system takes pictures of all vehicles passing a second loop and tracks the vehicles until they go out a street intersection. Traveling trajectory, approach lane, traffic signal and speed are used to decide whether the vehicle violates or not. The registration numbers and eight images of the violating vehicle are transmitted with an exclusive line to a central system at the metropolitan police agency.
