The invention discloses an urban traffic state monitoring and regional signal control system for an information physical fusion system, and the system comprises a traffic data multi-source fusion management subsystem which carries out the data mapping, data storage and transmission of physical entities of roads, vehicles and traffic signal equipment of a physical layer through data collection and processing; the traffic state monitoring subsystem is used for realizing real-time monitoring on the road state in an information layer by modeling an urban road network and monitoring the road congestion degree; the traffic congestion area identification subsystem is used for identifying and dynamically adjusting the congestion area of the road in an information layer; and the regional signal control subsystem is used for identifying boundary control nodes and key nodes in the region in the information layer, generating a signal lamp timing scheme, and performing feedback control on vehicles and traffic signal equipment in the physical layer to relieve road traffic congestion. According to the method, the regional congestion condition can be relieved by sensing, analyzing, deciding and controlling urban road traffic.
