The invention provides a road condition real-time monitoring device and belongs to the technical field of road traffic. The road condition real-time monitoring device comprises a control box, an accumulator, a controller, infrared emitting devices and infrared receiving devices, wherein the infrared emitting devices and the infrared receiving devices are symmetrically distributed on two sides of a road, and the distances from the first infrared emitting device, the second infrared emitting device and the third infrared emitting device to a vertical rod is 10 meters, 30 meters and 50 meters respectively. According to measurement results of the three infrared devices, the controller can judge the congestion situation of a road and accordingly can adjust signals of signal lamps in real time. The road condition real-time monitoring device is reasonable in design and simple in structure and is suitable for optimization design of crossing signal lamps.
