Traffic Signals

Traffic Signals in my project's world work a little differently then the real world.

Traffic Monitoring Camera

A Traffic Monitoring Camera (in this project) is a camera above traffic that when cars pull up to a signal, it checks other directions and if clear will turn green for the direction were the car is waiting. This is very helpful at nighttime were there is not much traffic.

Traffic Protection Camera 

A Traffic Protection Camera (in this project) is a camera aimed at each direction of traffic. When a light turns to red, all directions will be red in whats called a "clearance" phase to the intersection's traffic signals, during which all directions have a red light. At this time the other direction camera will check to make sure that traffic is stopped and no one shows they are going to run the light (ex. going high speed very near to the intersection) before giving the green light to a direction.
