The invention discloses an extra-long tunnel traffic accident congestion queuing dynamic prediction and control method, and relates to the technical field of traffic congestion prediction. The method comprises the following steps: dividing a tunnel into n sections of roads, and carrying out filtering processing on real-time flow and density data of each road section where an accident occurs; analyzing the vehicle queuing length in the tunnel in different accident occurrence stages and judging the accident type to determine the relationship between the background traffic volume and the residual traffic capacity of the tunnel; predicting the maximum queuing length of the vehicle; introducing a moving average filtering method to construct a vehicle queuing length real-time estimation model and calculating the vehicle queuing length real-time estimation model; judging the vehicle queuing condition in the tunnel; and different management and control measures are taken for different queuing length development stages. By establishing the vehicle queuing length real-time prediction model, the change condition of the vehicle queuing length in the tunnel can be reflected in real time, a theoretical basis is provided for a management department to take next management and control measures, and feedback is provided for the management department in real time.
