交通信息物理系统及其关键技术研究综述

Research Summary on Transportation Cyber Physical Systems and the Challenging Technologies

为了给智能交通系统(ITS)的发展提供参考,针对传统交通系统因缺乏广泛的互联互通互操作而尚未实现充分的协调与优化问题,考虑信息物理系统(CPS)是通过集成计算、通信及控制技术将信息基元与物理元素融为一体,并基于信息系统和物理系统之间的相互作用与反馈,以实现对物理系统的精确认知和有效控制的特点,将CPS概念引入交通系统,对交通信息物理系统(T-CPS)进行了研究。通过分析ITS与CPS的现状,并结合交通系统的特点,构建了T-CPS基本架构,诠释了T-CPS各层次的功能及特点,并对T-CPS和ITS进行比较,讨论了T-CPS的若干关键技术,同时给出T-CPS的实施思路与应用展望。研究结果表明:T-CPS的研究正符合交通物理对象及环境与交通信息空间深度融合的需要,将为下一代ITS发展提供理论支撑。

In order to provide reference for the development of intelligent transportation systems （ITS）, aimed at the traditional transportation systems which have not yet achieved fullcoordination and optimization due to lack of widespread interconnection, intercommunication and interoperability, and considering cyber physical systems （CPS） as multi-dimensional complexsystems, which integrate cyber element and physical element through the computation, communication and control technology to achieve the precise perception and effective control ofthe 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 theintroduction 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 {unctions 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 implementationsand 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 andprovides theoretical support for next generation of ITS.
