Fusion Framework of Urban Traffic Control and Route Guidance Based on Cyber-physical System Theory

Abstract

To avoid traffic congestion, improve transport efficiency, and meet the requirements of users and traffic flow equilibri­ urn, the fusion framework of urban traffic control and route guidance was studied. The characteristics of an urban traffic control and route guidance system and a cyber-physical system (CPS) were analyzed, and the relationship between such systems was examined. The technical requirements of the application of CPS theory to an urban traffic control and route guidance system were discussed. Based on the components of a dynamic urban traffic flow guidance system (UTFGS) and urban traffic control system ( UTCS), considering the man-machine system characteristics of CPS, and in the light of relevance, conflict, and solution method of both systems, a fusion framework for urban traffic control and route guidance based on the CPS was proposed. This framework involves computation, communication, control, and physical components that facilitate the enhancement of the fusion degree of the UTFGS and the UTCS. The proposed framework focuses on the technical analysis of the feasibility of the depth fu­ sion of both systems and provides a theoretical basis for the implementation of urban traffic control and route guidance fusion in intelligent traffic systems.
