The invention provides a coordinated optimization control method and system for a signal control intersection. The method comprises the steps of: obtaining a current signal timing scheme, and obtaining the traffic data of an intersection in a preset time period; constructing a multi-target nonlinear integer programming model according to the timing scheme and the traffic data, and establishing an objective function by taking minimization of vehicle average delay time in the timing scheme as an optimization objective; establishing an adaptive improved evolutionary algorithm, and taking the objective function as a fitness value of the adaptive improved evolutionary algorithm; and solving the multi-objective nonlinear integer programming model according to the adaptive improved evolutionary algorithm to obtain an optimal intersection timing scheme and using the optimal intersection timing scheme as an actual intersection signal timing scheme. According to the method, the average vehicle delay and the queuing length at the intersection can be effectively reduced, the CO emission amount is reduced, the vehicle traffic capacity in the intersection range is improved, and the optimization effect is more obvious under the frequent situation of flow distribution imbalance of different flows at the same phase in urban main roads and intersections.
