中国智能运输系统体系结构发展研究

发展适合中国国情的智能运输系统体系结构对于智能运输系统在中国的发展应用具有十分重要的意义，本文首先给出智能运输系统体系结构的定义，接着对智能运输系统的发展目的与意义、发展方法与发展原则作出简要的介绍；然后结合《中国国家智能运输系统体系结构（讨论稿）》，对智能运输系统体系结构委展程序中的3个主要步骤（用户服务定义、逻辑框架、物理框架）进行了详细描述，并且对用户主体、服务主体、用户需求、用户服务、系统功能、功能需求、数据流图以及物理子系统等要点进行阐述；最后对如何改进中国智能运输系统体系结构中所存在的不足及其今后的发展和应用提出了一些建议。

Research of Developing the System Architecture for Intelligent Transportation System in China

Developing system architecture for intelligent transportation system(ITS) which is suitable for native situation is very important to the application of ITS in China. This paper first gives the definition of system architecture, and describes the goals, methods and principle of developing system architecture for ITS in brief. Then based on the National System Architecture for ITS in China (Draft) , the authors give a detailed view of the developing program of system architecture for ITS that includes defining user services, building logical architecture and building physical architecture. The authors also expatiate upon the ITS users, ITS services provides, user demands, user services, system function, functions needs, data flow diagram and physical sub system. At last, Some suggestions on developing program and the application of the system architecture in future are presented.
