James E. Moore II, a professor of municipal and environmental engineering at the University of Southern California, said it was the "first use" of such a sophisticated Traffic Light system in the United States. But he added that any Traffic Light synchronization system, no matter how advanced or complex it is, is unlikely to eliminate congestion in the long run.

In the practical application of Radar Speed Signs, users often encounter some technical problems that are not product quality problems. A large part of the problem is that Radar Speed Signs is interfered by certain factors, which may cause inexplicable speed measurement errors. The following is given by Henan Ruichen Traffic Equipment Co, Ltd. to customers who often encounter problems discussed by Radar Speed Signs, radar speed measurement The speed measured by the instrument is lower than the actual speed.

Nowadays, with the continuous improvement of our country's economic level, more and more people have become car owners. In order to ensure the safety, order and smooth flow of roads, we need to install Solar Signal Lights at busy intersections to direct traffic. The use of Solar Signal Lights can effectively reduce traffic accidents, improve traffic efficiency, and improve traffic conditions.

Solar Traffic Lights consists of red lights, green lights, and yellow lights. A red light means no access, a green light means permission to pass, and a yellow light means a warning.

Solar Traffic Lights has played an indelible contribution in coordinating urban traffic congestion. In view of the artificial distance between the traffic management of central and western cities compared with central and eastern cities, it is recommended to increase the efficiency of road construction and scientifically regulate Solar Traffic Lights.

Solar Signal Lights are divided into motor vehicle signal lights, non-motor vehicle signal lights, pedestrian crossing signal lights, lane signal lights, direction indicator lights, flashing warning lights, and Solar Signal Lights at road and railway level crossings. Solar Signal Lights are used at road level intersections.
