The embodiment of the invention discloses a regional traffic signal cooperative control system and method, and relates to the technical field of intelligent traffic. The system comprises a traffic control decision center which performs data fusion analysis according to historical traffic data information of a current intersection in a predetermined area and upstream and downstream intersections in a predetermined traffic area and traffic parameter information and road traffic condition information in the predetermined area in a predetermined time period, obtaining the duration threshold of each phase of the current intersection and the upstream and downstream intersections; the intelligent signal machine is used for calculating and obtaining a preliminary timing scheme of the current intersection according to a preset single-point self-adaptive timing algorithm based on the traffic parameter information of the current intersection; and adjusting the initial timing scheme according to the duration threshold values of each phase of the current intersection and the upstream and downstream intersections to obtain a final timing scheme of the current intersection. According to the invention, a traffic signal timing scheme is convenient to optimize, so that the road traffic capacity can be improved to a certain extent; the method is suitable for traffic light control scenes.
