The invention relates to a traffic signal optimal control method for road intersection vehicle coordinated optimization. Compared with the prior art, the method solves the defect that monitoring, regulation and control on signal lamps by images can not be suitable for coordinated optimization optimized control. The method comprises the following steps that traffic flow parameters of road intersections are obtained; the queuing lengths are calculated; the intersection coordinated optimization states are judged; the green lamp releasing time of each upstream intersection is calculated. According to the traffic signal optimal control method for the road intersection vehicle coordinated optimization, vehicle detectors installed on the inlet-outlet ports of the road intersections are used for detecting the parameters of the queuing lengths and coordinating to optimize events in real time, and through regulation of the green lamp releasing time controlled by traffic signals, and the problems of uniform queuing lengths of the intersections in the region and the coordinated optimization of the intersections are achieved.
