Abstract

In response to the disadvantages of the traditional road traffic signal control field, such as the large number of traffic information devices, high maintenance cost, many failure hazards, and lack of scalability of the system, we propose a distributed road traffic signal control system method based on 5G network. The system includes a radar-video integrated unit, which collects traffic flow data at intersections through radar and video sensors, and sends the collected flow data to the intersection control center through a 5G network; a distributed control signal, which collects signal unit operation status through voltage and current sensors, sends the signal unit status to the intersection control center through a 5G network, and accepts and executes the intersection control center's issued operation scheme; intersection control center, according to the received intersection traffic flow data and signal status information analysis to generate intersection direction scheme, send the intersection release scheme through 5G network to the radar video integrated machine and distributed control signal, and complete the control node autonomous monitoring function. We tested the proposed method by building a verification platform. The experimental results show that the adoption of this method can greatly reduce the intersection wiring workload and improve the system usability.
