Intelligent Transport System and Its Informatics Model
-
摘要: 智能交通系统(Intelligent Transport System,简称ITS)是在传统的交通工程基础上发展起来的新型交通系统,其研究对象是人、车、路和环境交通四要素的空间与时间关系,又可以称之为广义的交通信息.本文在介绍国际上ITS研究状况的基础上,首先给出了ITS的系统组成,而后从信息技术的角度阐明ITS是一个交通信息获得、传输、处理而后利用的信息系统,提出了ITS的信息化模型,最后简述了ITS中的信息技术四基元.Abstract: ITS(Intelligent Transport System) is a new transport system evolved from the traditional traffic engineering. The research object of ITS is the spatial and time relationship of people, vehicle, road and environment which are named four transport elements together, and it is called transport information in broad sense. Firstly, the system frame is presented on the basis of introduction of international ITS research, and then it is proposed in the aspectof information technology that ITS is an information system where transport information is collected, transferred, processed and exploited. Informatics model is given too. Finally, the four basic elements about information technology in ITS are described.
