智能交通系统包含许多研究内容,其中车辆定位技术是目前的主要研究与开发热点之一。本文介绍了各种定位方法,阐述了公交车辆定位的特点,着重探讨适用于公交车辆的定位技术。在分析全球定位技术和站点信标定位技术的基础之上,文章提出了一种新思路——驾驶员辅助定位技术,由驾驶员在停靠公交站点时操纵车载装置,将定位信息通过通讯链路发送给监控调度中心。文章综合比较了全球定位技术、站点信标定位技术、驾驶员辅助定位技术的性能。
Intelligent transportation system contains a lot of research contents, among them the vehicle localization technology is one of the main research and development hotspots at present. This article introduces various positioning methods, expounds the characteristics of bus positioning, and focuses on the positioning technology suitable for buses. Based on the analysis of global positioning technology and station beacon positioning technology, this paper presents a new idea - driver-assisted positioning technology. When the driver stops the bus stop, the driver controls the vehicle-mounted device and sends the positioning information through the communication link Send to the monitoring and control center. The article comprehensively compares the performance of global positioning technology, site beacon positioning technology and driver assistance positioning technology.
