为了给智能交通系统(ITS)的发展提供参考，针对传统交通系统由于缺乏广泛的互联、互通和互操作而尚未实现充分的协调和优化，并将网络物理系统(CPS)视为多维复杂系统，通过计算、通信和控制技术将网络元素和物理元素结合在一起，通过网络系统和物理系统之间的相互作用和反馈来实现对物理系统的精确感知和有效控制，对交通网络物理系统(T-CPS)进行了研究。在分析交通网络物理系统(T-CPS)的基础上，对交通网络物理系统(T-CPS)进行了研究。针对交通系统的特点，提出了T-CPS的基本体系结构，阐述了T-CPS各层的功能和特点，通过与T-CPS的比较，讨论了T-CPS的一些关键技术，并给出了T-CPS的实现和应用。结果表明，T-CPS的研究充分体现了交通网络世界和交通物理世界的深度融合，为下一代智能交通系统提供了理论支持。
In order to provide reference for the development of intelligent transportation systems(ITS),aimed at the traditional transportation systems which have not yet achieved full coordination and optimization due to lack of widespread interconnection,intercommunication and interoperability,and considering cyber physical systems(CPS) as multi-dimensional complex systems,which integrate cyber element and physical element through the computation,communication and control technology to achieve the precise perception and effective control of the physical systems via the interaction and feedback between the cyber systems and physical systems,the study of transportation cyber physical systems(T-CPS) was carried out with the introduction of CPS into the transportation systems.Based on the analysis of ITS,CPS and the characteristics of transportation systems,the fundamental architecture of T-CPS was proposed,the functions of corresponding layers and characteristics of T-CPS were explained,through the comparison of T-CPS and ITS some key techniques of T-CPS were discussed,and the implementations and applications of T-CPS were also presented.The results show that the study of T-CPS fully embodies the deep fusion of the transportation cyber world and transportation physical world and provides theoretical support for next generation of ITS.
