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. They can detect the number of vehicles waiting at an intersection and adjust the signal timing accordingly, reducing congestion and improving safety. These systems often incorporate technologies such as cameras, radar, and infrared sensors to gather data. Additionally, smart traffic lights can communicate with connected vehicles and other infrastructure, allowing for coordinated traffic management and smoother travel experiences for drivers and pedestrians alike.
