In response to the phenomenon of “traffic jams” that prevails in urban centers, our company successfully developed this system after more than one year of research. The commonly used intersection red and green light command systems can only be controlled according to a fixed time sequence. It does not have the function of judging the traffic volume and statistics, and does not automatically adjust the functions of the red and green lights in the corresponding directions according to the traffic volume. The successful development of this system completely solved the above problems. Using it can greatly improve the traffic efficiency at the intersection of the downtown area and effectively solve or alleviate traffic jam at the intersection. Using it can also save a lot of manpower, material resources, and financial resources for the traffic management department. The system has advanced design ideas and reasonable hardware/software matching. This system has the characteristics of being applicable, reliable, and convenient to maintain while possessing advanced technology and low investment.
