Do you know that many urban traffic lights have achieved intelligent control?

Intelligent traffic signal lights have the capabilities of perception, interconnection, analysis, prediction, control, etc. They can monitor the queue, passage, distance, and speed of vehicles at intersections in real time, automatically adjust the release time of traffic lights based on traffic flow, match suitable signal timing, reduce empty spaces, reduce vehicle queuing, and improve road traffic efficiency.

The "green wave" control of traffic signals is a practical function of intelligent signal systems, commonly referred to as the "green wave zone". It uses an intelligent signal light system, which automatically adjusts the interval time between traffic lights through a computer, reasonably allocates signal cycles, and prioritizes the passage of vehicles at intersections with high traffic flow. During peak hours, reduce the interval between traffic lights and allow vehicles to queue up less and pass quickly. When encountering continuous traffic flow, as long as the driver controls the speed well, he can "green light all the way" to let the vehicle go all the way to the end. When the traffic pressure of a road increases, it can adjust the length of the signal lights in advance at the surrounding intersections to guide the vehicles to pass at intervals.

If some pedestrians or non motorized vehicles run red lights or cross the road, change lanes and drive recklessly, the rear vehicles will not reach the standard speed, and the function of the green wave belt will be disturbed and not achieve the expected effect. In addition, motor vehicles should not exceed the speed limit, otherwise they will not reach the speed limit, and the "green wave belt" will not reflect the "green wave" effect.
