The invention discloses a road network traffic optimization control system and method, belonging to the field of traffic. The method comprises: traffic data of a road network, especially intersection turning flow data and section divisional flow data, is extracted based on fusion analysis on vehicle-mounted GPS/Beidou positioning data and fixed detector data; a method for detecting a road network traffic state with travel delay index two-dimensional coordinates as characterization parameters is provided, and the road network state is represented by a region range; based on user travel path analysis data, a dynamic dividing method for traffic coordination control cells is provided; by adopting road upstream and downstream traffic capacity analysis technology and with a control target of regional road network traffic optimization, a linked optimization method for a control scheme of signals at crossroads near a regional key intersection is provided; and an intersection signal control adaptive optimization method based on a traffic delay index is provided. The method improves the active prevention and control capability of the control system for road network congestion.
