The invention discloses a regional traffic signal lamp control method and device, equipment and a medium, and relates to the field of traffic signal control, and the method comprises the steps: building a state space containing a plurality of driving states of a vehicle, and a motion space containing signal lamp constraints and intersection passing strategies; determining a matrix grid formed by a plurality of intersections on the road network model, dividing the matrix grid into a plurality of types of cells, and endowing each type of cells with different weights; adopting a Benders decomposition algorithm and an alternating direction multiplier algorithm to establish an optimal problem of multiple types of cells of the region, and iteratively solving the optimal problem to obtain a reward space of a vehicle driving at each intersection of the region; and taking the state space, the action space and the reward space as input parameters of the double-depth Q network, training the double-depth Q network, and applying the trained double-depth Q network to control of regional traffic lights. According to the invention, continuous regional road network signal lamps can be controlled and optimized, and the traffic capacity of regional vehicles is improved.
