Tunnel intelligent traffic management and control system and method

The invention relates to the technical field of vehicle traffic control, and provides a tunnel intelligent traffic control system and method, and the method comprises the steps: obtaining a tunnel driving data sequence and a detection vector; determining a multi-mode characteristic state diagnosis coefficient based on the variable quantity between adjacent peak points on a time sequence curve of each element in the tunnel driving data sequence and the change regularity of the detection vectors at each acquisition moment and a historical acquisition moment; determining a data stagnation coefficient based on the dispersion degree of elements in a label stable sequence of the state transition probability matrix of each modal data under different time scales; and adaptively determining a fading gain based on the data stagnation coefficient and the two-end dragging influence coefficient, obtaining a state detection fusion vector by adopting a KF algorithm, obtaining a vehicle motion state detection result based on
