Traffic safety issues are significant societal problems. To maintain a sense of order in traffic, traffic lights have become a crucial product. With the proper guidance of this product, the safety of traffic on the road can be enhanced. However, when learning about this product, users are often concerned with the control methods utilized in its operation, and many seek to enrich their knowledge in this area.
Firstly, timed control is a commonly used method for traffic lights. This can be observed in the red and green configurations at various intersections. The duration of vehicle flow and waiting time in each direction must comply with the signals, providing strong guidance for both vehicles and pedestrians, effectively enhancing safety.
Secondly, there is sensor control. In some areas, the volume of traffic and pedestrian flow is not particularly high. However, to ensure traffic safety, the installation of traffic lights becomes essential. In such cases, the control method is often sensor-based, which detects whether there are pedestrians or vehicles present, resulting in corresponding changes to the traffic lights.
Through this understanding of traffic light control methods, one can also recognize that adaptive control has become a necessary controlling approach. This method allows for adjustments based on actual conditions, significantly aiding in effective traffic regulation.
