The invention discloses a distributed road traffic signal control system based on 5G communication, and belongs to the field of road traffic signal control. The distributed road traffic signal controlsystem comprises an intersection control center, a distributed control signal lamp and a radar and video all-in-one machine; the radar and video all-in-one machine collects intersection traffic flowdata through a radar and a video sensor and sends the collected flow data to the intersection control center through a 5G communication network; the distributed control signal lamp collects the operation state of a signal unit through a voltage sensor and a current sensor, sends the state of the signal unit to the intersection control center through the 5G communication network, and receives and executes an operation scheme issued by the intersection control center; and the intersection control center analyzes and generates an intersection direction scheme according to the received intersection traffic flow data and signal lamp state information, sends an intersection release scheme to the radar and video all-in-one machine and the distributed control signal lamp through the 5G communication network, and completes a control node autonomous monitoring function. According to the distributed road traffic signal control system, the 5G communication technology is utilized, the functions ofan annunciator are preposed, the intersection wiring workload is reduced, and the system availability is improved.
