Smart traffic lights are an intelligent transportation system that can alleviate traffic pressure and maximize the efficiency of intersections. They are also an important project for building smart cities in the future. Their main functions include:
1. Safety reminder broadcasting and remote advertising placement;
2. One click pedestrian priority, caring for potential groups;
3. Monitor the traffic conditions, pedestrian and vehicle flow at intersections;
4. Pedestrian running red light detection, voice prompt and facial capture when someone runs red light;
5. Paired with red/green/yellow flashing ground lights to make traffic flow more intuitive and municipal services more aesthetically pleasing.
