P18393: Traffic Light Cameras to Optimize Flow


Project Summary Project Information

The traffic light is a device that controls what directions of the intersection are given the right of way. When a a car approaches an intersection with a green light and the intersection is clear of obstacles, the car may proceed to go through the intersection. During lighter traffic times, cars often have to come to a complete stop when approaching a red light with no other cars in sight.

In today's world, the current and most widely used technology to detect vehicles is the induction loop. This technology uses large coils in the ground to emit frequencies. Once a vehicle drives over or sits over the coil, eddy currents are induced into the coil which decreases the overall inductance. A controller notes the decrease in inductance as the presence of a vehicle which then tells the traffic controller there is a vehicle waiting. This system is expensive as it requires cutting the pavement of a road to lay down the coil and then repaving over the coil.

This project focuses on creating a new and improved traffic light system that is designed to decrease the average waiting time at traffic lights, which will directly decrease emissions from vehicles. This can be accomplished by making the intersection "smarter." That is, the intersection will need to detect the number of cars approaching earlier and this information will be put into an algorithm to determine which direction should receive the green light. By tracking cars before they get to the intersection, this will help reduce making a car perform an unnecessary stop for no traffic.
