The invention discloses an expressway low-speed driving vehicle identification method, which belongs to the technical field of intelligent traffic systems and big data processing, and monitors and analyzes interval speed information of a vehicle passing through a portal frame in real time through data analysis association on the basis of a portal frame database. The vehicles with the interval running speeds lower than a set low-speed threshold value are regarded as low-speed running vehicles, and the running speeds of the intervals corresponding to the low-speed running vehicles are predicted based on the road features, the historical driving behavior features and the running time features of the interval distances corresponding to the low-speed running vehicles; the low-speed alarm information is generated for the time interval when the interval prediction speed is smaller than or equal to the interval driving speed, the formation factors of the low-speed driving vehicle are comprehensively analyzed, real-time prediction and early warning of the vehicle with the low-speed driving risk are achieved, the judgment response speed and the accuracy degree of the low-speed driving vehicle can be improved, and the accuracy of the low-speed driving vehicle is improved. Therefore, the road traffic safety and the passing efficiency are improved.
