智能交通系统研发历程与动态述评

Review of the Process and Dynamics of ITS Research and Developments

对智能交通系统(ITS)进行了整体描述,回顾了美国、日本和欧洲的ITS发展历程,并结合其研发动态对国外ITS研发特点做出评述。介绍了国外ITS未来的建设目标,指出发达国家已经不是将ITS仅仅看成解决交通拥堵的工具,而是将其看作解决能源和环境问题的可选项,ITS的研发应注意与能源、出行权利以及交通安全的关系。最后,指出ITS发展需要实现真正的学科交叉和交融,并讨论了国内ITS未来发展的研究方向:注重信息技术应用条件下交通系统的描述方法以及交通系统的状态表达和人的行为研究。

ITS Development in the United States, Japan and Europe were reviewed to provide an overview, ITS development trends were also observed considering the development state. This paper introduces goals of ITS Development abroad and shows that the developed countries have adopted ITS not only as a tool for solving traffic jam problems, but also as an option for solving energy and environmer;tal problems. Issues concerning energy, travel rights and safety should also be addressed while developing ITS. Finally, the paper points out that interdisciplinary is necessary for ITS R＆D in China, and that methods for describing transportation systems, and expressing traffic status and human behaviors are all important when applying information technology.
