The invention discloses an evacuation traffic control optimization method, which comprises the following steps: acquiring data of a current local sudden disaster scene, an evacuation traffic demand scene and a road network structure and attributes, establishing an objective function according to the acquired data of evacuation traffic control optimization, and constructing a mixed integer linear programming model as a constraint condition; an optimal solution of the evacuation traffic control optimization model is solved by calling a solver, and an evacuation traffic control optimization scheme of the disaster-affected area road network is obtained; based on the obtained evacuation traffic control optimization scheme, an objective function and constraint conditions of current real-time evacuation traffic control optimization are established; and circularly executing the steps, and obtaining a final evacuation traffic control optimization scheme by simulating different disaster scenes, evacuation traffic demand scenes and road network structures and attributes. According to the invention, by obtaining the lane reverse direction and cross conflict steering control rule of evacuation traffic operation under local sudden disasters, an evacuation traffic control optimization scheme is planned for potential disasters.
