A service-oriented architecture for the transportation Cyber-Physical Systems

The emerging concept of CPS (Cyber-Physical Systems) is introduced into transportation systems in the present paper, which satisfies the need of tight fusion of transportation physical systems and transportation cyber systems. Considering the characteristics of a transportation system, a service-oriented architecture for the Transportation Cyber-Physical Systems (T-CPS) is put forward, including the perception, communication, computation, control and service, and then the function of each corresponding layer is carefully designed. In the final, some key techniques and applications of T-CPS are also discussed, which can lay foundations for next generation of ITS (Intelligent Transportation Systems).
