The invention discloses an urban road intersection traffic information acquisition system based on an image recognition technology. The urban road intersection traffic information acquisition system comprises a lane image data acquisition platform and an image data analysis platform. The image data acquisition platform comprises a video acquisition module and a video decoding module, wherein the video acquisition module acquires video image data of each intersection in the morning peak and evening peak periods; and the video decoding module is used for decoding the real-time video of the videoimage data acquired by the video acquisition module so as to acquire image data of each frame. The image data analysis platform comprises a video recognition processing module and a second calculation module, wherein the video recognition processing module recognizes a vehicle object through the obtained image data of the frames and recognizes each lane of each intersection; and the second calculation module is used for calculating the average waiting time of the vehicles in each lane in each preset period. According to the urban road intersection traffic information acquisition system, the image recognition technology is combined with traffic management, traffic information of the intersections is effectively obtained, so that notification and planning are made in advance, and thereforethe purposes of optimizing traffic and guaranteeing safety are achieved.
