INTELLIGENT DECISION SUPPORT MANAGEMENT SYSTEM OF URBAN ROADWAY NETWORK

摘要

Application of Intelligent Decision Support System (IDSS) in urban roadway traffic management is studied, and four parts are addressed in order to create a viable and useful decision-support system. Firstly, the implementation framework of Road Traffic Intelligent Decision Support System (RTIDSS) is put forward, more then; the model base, data base and method base are described in detail. Here, the data base of RTIDSS is developed based on Integrated Traffic Information Platform, which has the function of information collecting, processing, communication and information sharing. In the third part, with the knowledge of traffic engineering, especially traffic flow theories, traffic model base of RTIDSS is presented. And in the last the paper takes into account general strategies in urban expressway management such as road traffic monitoring, traffic signal control, ramp metering, variable traffic information guidance and incident management. The aim of the development of RTIDSS is to improve transportation efficiency and realize the intelligent management of urban roadway traffic.
