The invention provides an emergency lane dynamic management method and system, and the method comprises the steps: obtaining historical monitoring videos of all monitoring points, and carrying out the video processing of the historical monitoring videos; extracting vehicle information in the processed video, and redefining and calculating traffic flow parameters according to the extracted vehicle information; according to the traffic flow parameters, constructing a traffic flow interruption probability model, and determining a final threshold value of emergency lane opening; based on the traffic flow parameters and the final threshold, training the multiple classification models; training a traffic jam early warning model according to the traffic flow parameters; a monitoring video of a target monitoring point in a target time period is obtained, video processing and data extraction are carried out, based on the calculated real-time traffic flow parameters, a traffic jam early warning model is used for processing, and traffic flow density and an early warning point are predicted; and according to the prediction result, using multiple classification models to decide whether to open the emergency lane, and fusing all decision results. According to the invention, the use of the emergency lane is optimized.
