The invention provides a road condition congestion feedback system and belongs to the technical field of road traffic. The road condition congestion feedback system comprises a control box, an accumulator, a controller, infrared emitting devices, infrared receiving devices and a wireless signal sending device, 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 congestion feedback system is reasonable in design and simple in structure and is suitable for optimization design of crossing signal lamps.
