The invention provides a system and method for recording the behavior that motor vehicles entering a rotary island do not avoid motor vehicles in the rotary island. The method includes the steps that the motor vehicles getting ready to enter the rotary island and the motor vehicles already travel in the rotary island are continuously tracked through a video tracking device in real time, when the motor vehicles getting ready to enter the rotary island enter a video tracking range, the system carries out screenshot and license plate recognition on the motor vehicles, the recognized license plate numbers are directly marked on the images of the motor vehicles in the picture, and when the adjacent motor vehicle shields the license plate number of the previous vehicle, the system can accurately know the shielded license plate number of the vehicle; at the moment that as one motor vehicle entering the rotary island goes beyond a stopping line, the corresponding motor vehicle in the rotary island slows down or stops, or the distance between the motor vehicle entering the rotary island and the corresponding motor vehicle in the rotary island is smaller than a set distance threshold value, the motor vehicle goes beyond and enters the rotary island is photographed, and the license plate number marked on the motor vehicle image, the screenshot obtained when the motor vehicle entering the tracking range, and the evidence of slowdown, stopping and the distance smaller than the set threshold value are synthesized and then transmitted to a database for the illegal behavior that the motor vehicles entering the rotary island do not avoid the motor vehicles in the rotary island.
