Securing road intersections through non-invasive, image analytical solution

Red light solutions detect vehicles that pass the traffic light when it is red. The result of this solution is a list of potential red light violators, including:

> Speed of the vehicle, 
> Image before and after the red light, or a video,
> Red light status on each image,
> Orange light duration before red light.

The hardware set-up requires the exact status and timing of the traffic light to be able to unambiguously determine the violation. This is possible either via a hard-wired signal from the controller or thanks to the appropriate location of the camera, from where it can see the traffic light status. Furthermore, a virtual loop, or also called ROI (region of interest), is predefined within the camera. If the vehicle is in this monitored ROI within a predetermined time window after initiating the red light, it is possible to speak of a potential offender.

In general, there are two options to monitor the red light location: from the front or from the back. Both options are possible, but each requires different hardware setups.
