Dynamic and static differences of traffic lights

The control technology is different. Static control is a traditional traffic light control method, and its green light duration is fixed in advance and usually optimized according to traffic flow and speed. This control method may appear "dull" when the traffic flow changes greatly, and it cannot adapt to the changes of traffic conditions in real time. Dynamic control is a more advanced traffic light control technology. By using advanced technologies such as sensors and intelligent algorithms, it can sense information such as traffic flow and speed in real time, and adjust the green light duration in real time according to these information. This means that dynamic green wave control can be automatically optimized according to real-time traffic conditions, and the traffic efficiency and safety of roads can be improved.
