Research Of Intelligent Transport Control System Based On Multi-Agent System(MAS)

Transportation problem is an important problem all over the world, the traditional transportation control based on precise mathematics models is complex and the effects of their application always not reach the expectation. Multi-agent technology is a hotspot in the artificial intelligent field. One agent controls its object automatically and initiatively. The cooperation of agents can improve the intelligence of the whole system.This thesis introduces the agent theory and the concept of the Multi-Agent System (MAS). It aims at the actuality of the intelligent transportation control system and the problem of the current study of transportation control system that includes non-linear, uncertain, time-changeable and uncompleteness, by applying agent technology to traffic control system, presents the intelligent transportation control system based on multi-agent technology. In the system, one intersection agent was disposed at each intersection, supervised by the master agent of system, and the function of traffic agents is discussed and the coordination problems between traffic agents are described. The partial global coordination method was used to program thewhole control process. In each intersection agent, the widesence knowledge model was used to realize the control strategy, and the control process of forecasting and corresponding and adjusting basing on induction was used to achieve the control, and the study method of dynamic programming was used to establish the initial control project, and Game Theory was used to realize the correspond with the adjacent intersection agent and the master agent, and the method of direct communication of point to point was used to carry out the communication with the adjacent intersection agent and the mater agent. At the same time, the intelligent transportation control system based on multi-agent technology is simulated preliminarily with Delph7.0. The simulation result shows that the intelligent transportation control system based on multi-agent technology, which is an intelligent transportation control system with new architecture, can adapt well to the complexity and randomness of transportation and overcome drawbacks of traditional transportation control methods.
