A road traffic monitoring system based on 4D millimeter-wave radars and a video sensor array comprises a plurality of radar camera sensor units which are used for sensing the position, speed, height, light, license plates and road environment of vehicles on a road and adopt a multi-sensor array layout, the 4D millimeter-wave radars and video sensors are installed on the two sides of the road, and the radar camera sensor units are used for sensing the position, the speed, the height, the light and the license plates of the vehicles on the road. Full coverage of a road monitoring area is achieved, and meanwhile long-range trajectory tracking of a vehicle is achieved through fusion between radars; the cloud processing system unit is used for processing and analyzing the road vehicle driving state and the road driving environment according to the 4D millimeter wave radar data and the video data acquired by all the radar camera sensor units in the monitoring area, extracting abnormal information and implementing early warning; and the alarm and early warning unit is used for receiving the information of the cloud processing system unit and providing early warning for passing vehicles. According to the invention, whole-section monitoring of road traffic can be realized, more complete target vehicle information and environmental perception are provided, and early warning is provided.
