traffic signal controllers
Traffic signal controllers are programmable devices that manage how traffic lights operate at intersections. They coordinate the timing of red, yellow, and green signals to ensure safe and efficient vehicle and pedestrian movement. These controllers can be set to operate on fixed schedules or adapt dynamically based on real-time traffic conditions, often using sensors or cameras. They help reduce congestion, prevent accidents, and improve flow by synchronizing lights across multiple intersections, making urban traffic management more organized and predictable.
