The primary, reliable and most common traffic light sensors are induction loops. Induction loops are coils of wire that have been embedded in the surface of the road to detect changes in inductance, then conveying them to the sensor circuitry in order to produce signals.

These coordinated signal systems try to ensure that lights dont turn red just as cars are arriving, or have a car waiting at a red light when no cross-traffic is going through the intersection. Traffic signals are designed to ensure an orderly flow of traffic, provide an opportunity for pedestrians or vehicles to cross an intersection and help reduce the number of conflicts between vehicles entering intersections from different directions. They are safer, and traffic still seems to flow. Inventor Garrett MorganBlack Inventor Garrett Morgan Saved Countless Lives with Gas Mask and Improved Traffic Lights.
