It looks like you need to use multiple cameras at each intersection to achieve this (an overview plus detail cameras for lpr). From what I have seen in the US, they usually only have 1 camera per intersection. As such, I do not believe they could simply add this software on to existing cameras. They would need to roll out more cameras. See excerpt below: "The overview camera detects and documents the phase of the traffic light as well as records the situation in the intersection and the motion of a vehicle into the intersection. The high-resolution detail cameras are recording the vehicle at the stop-line, the entire driving lane including its boundaries (necessary to record vehicles traveling between driving lines), the license plate and the driver‘s face."

I don't have any technical info, but it would be a great feature to have for red light cameras. Think of how much time could be saved in processing tickets! (Along with the added surveillance capability). I will keep poking around and keep you updated. For the speed cameras, there are already systems that utilize LPR.

I have seen a number of these cameras and they are generally positioned high (10 feet or more above the ground) and far from the car (30 - 50 feet away). Those logistical conditions are generally poor for performing LPR as the application demands a high number of pixels for the image and a low angle of incident to the numbers. Best, John Hi Rajiv,
