Traffic control refers to the methods and systems used to manage the flow of vehicles and pedestrians on roads. This includes the use of traffic signals, signs, and road markings to ensure safety and efficiency. Traffic control helps prevent accidents and reduces congestion by guiding drivers and walkers on how to navigate intersections and roadways. In addition to signals and signs, traffic control can involve the presence of traffic police or road construction crews who direct vehicles during special events or roadwork. Advanced technologies, such as traffic cameras and smart traffic lights, are also used to monitor and adjust traffic patterns in real-time, improving overall road safety.
