The invention provides an urban congestion road network closure signal control method, device and equipment and a medium, and relates to the technical field of traffic management, and the method comprises the steps: determining a congestion affected area according to obtained road network traffic data; based on traffic demand correlation analysis and traffic state correlation analysis, determining a comprehensive correlation value between the intersections of the congestion influence area, constructing a weighted road network topological graph of the congestion influence area according to the comprehensive correlation value, and determining an optimal interception path according to the weighted road network topological graph; and determining the flow rate ratio adjustment amount according to the optimal interception path and the road network traffic data, determining the flow value adjustment amount of each intersection according to the flow rate ratio adjustment amount, and distributing the green light duration of each intersection according to the flow value adjustment amount. According to the method, quantitative analysis on the relevance between the intersections is achieved from the two aspects of traffic demand relevance analysis and traffic state relevance analysis, congestion transfer in the evacuation control process is avoided, and efficient evacuation control on accidental congestion is achieved.
