Traffic signal control refers to the management of traffic lights at intersections to ensure the safe and efficient movement of vehicles and pedestrians. This system uses various signals, such as red, yellow, and green lights, to indicate when to stop or go. The timing of these signals can be adjusted based on traffic flow, time of day, and other factors to minimize congestion and reduce the risk of accidents. Modern traffic signal control systems often incorporate technology like sensors and cameras to monitor real-time traffic conditions. These systems can adapt to changing traffic patterns, improving overall road safety and efficiency. Additionally, some cities are implementing smart traffic signals that communicate with connected vehicles to optimize traffic flow further.
