Smart traffic lights are advanced traffic control systems that use sensors and algorithms to manage vehicle and pedestrian flow more efficiently. Unlike traditional traffic lights, which operate on fixed timers, smart traffic lights can adapt in real-time to changing traffic conditions, reducing congestion and improving safety. These systems often incorporate cameras, radar, or infrared sensors to detect the presence of vehicles and pedestrians. By analyzing this data, smart traffic lights can adjust their timing, prioritize emergency vehicles, and even communicate with connected vehicles, enhancing overall traffic management in urban areas.
