I was messing around on google maps (I live in England) and never seen this camera type before on traffic lights. Is this a camera that's designed to see if people run red lights or not?
Here is a full view of the junction, you can see this camera above the light in the middle
Actually I believe this is a camera that catches those who go through red lights. So as the above camera is at a junction, would it be used to detect cars to change the lights?
