Study and Design of Traffic Management Decision Support System Based on Grid

The challenge with which traffic management decision support system is faced in information age is first analyzed in this paper. Then, the idea to integrate the existing traffic information to improve decision level is proposed. Two kinds of advanced technology including artificial intelligence and Grid are used to construct the framework of traffic management decision support system based on Grid. The framework is mainly made up of such main parts as Grid node, WAN, and Grid middleware. Grid middleware includes resource management and task scheduling middleware, decision support middleware, information analysis middleware and virtual data center middleware. The function, model, and operation mechanism of Grid mlddleware are explained in detail, and the operation process of the system is also given. Through application in the real system, the intelligentization level and efficiency of traffic management decision have been greatly improved.
