摘要
介绍了市区车辆导航监控与交通管理系统的基本组成和差分ＧＰＳ（ＤＧＰＳ）原理及其信息校正方法，分析了ＤＧＰＳ应用于该系统的可行性，在此基础上提出了三种系统组成方法，并进行了分析比较，最后简要介绍了坐标系统转换及电子地图实时显示等问题。本文的研究结果对于进行ＩＶＨＳ系统研究具有重要意义。
This paper firstly introduces the general composition of the traffic management information system for urban vehicle navigation and monitoring. Then the principles of differential GPS (DGPS) and its data corrections methods are introduced, and the availability of DGPS to the system is analyzed. On the basis of above analysis, three methods, in which the traffic management information system for urban vehicle navigation and monitoring are composed, are presented, and their performance is analyzed. The work of this paper is very useful for the research of IVHS.
