摘要
介绍了专用短程通信(DSRC)系统和DSRC协议的结构,构建了基于DSRC的停车引导和信息系统(PGIS)的总体结构,讨论了各个组成部分的功能,结合广州市具体实施情况阐述了PGIS的系统构成。讨论了PGIS需提供的静态和动态信息以及当前广州市PGIS提供的信息。研究了PGIS提供的停车诱导、自动收费、停车位预定等功能的实现,分析了PGIS的特点,最后指出了实现PGIS过程中应考虑的关键问题。
This paper introduced DSRC configurations and its protocol.It built up the architecture of PGIS based on DSRC and discussed the function of each part.The components of Guangzhou PGIS as an example were expatiated.The provided information by PGIS,including static and dynamic data,was discussed.The implementation of the functions provided by PGIS,such as parking guidance,electronic toll collection,park reservation service,was discussed.The characteristics of PGIS was analyzed.The key problems in the implementing PGIS were put forward.
