How Traffic Lights Work

The video tutorial explains the function and control systems of traffic lights. It covers the basic operation of traffic lights, including the meaning of different colors. The tutorial then delves into four control systems: fixed rate, dynamic, coordinated, and adaptive control. Fixed rate control operates on a set schedule, while dynamic control uses sensors to adjust signals. Coordinated control synchronizes multiple lights, and adaptive control adjusts based on traffic volume, often managed by traffic agencies.
