The agent computing is rapidly emerging as one of the powerful technologies to deal with the uncertainty of large-scale distributed systems in a dynamic environment.The domain of transportation systems is well suited for an agent-based approach because of their geographical and logical distribution in dynamic changing environments.This paper has surveyed the techniques and methods resulting from the field of agent and multi-agent systems that have been applied to many aspects of traffic control systems,including system architecture,control algorithm,modeling and simulation,and intelligent traffic management.Then,an agent-based approach and its applications in the domain of traffic control,both in China and abroad,are also examined.Finally,several future research directions toward the successful deployment of agent technology in traffic control systems are discussed,and there critical issues in developing agent-based traffic control systems for integrated network are addressed as interoperability,adaptability,and extendibility.
