电子不停车收费技术综述

Survey on 5.8 GHz Electronic Toll Collection Technologies

摘要:

电子不停车收费(ETC)是智能交通系统(ITS)的重要组成部分，5.8 GHz已成为国际ETC系统的主流频段.我国2007年颁布的国家标准也规定了中国ETC系统使用5.8 GHz通信频段.从我国ETC技术标准出发，阐述了5.8 GHz ETC系统构成和实现原理，综述并分析了5.8 GHz ETC系统的关键技术，指出了5.8 GHz ETC技术今后的研究方向和发展趋势.

Abstract:

Electronic toll collection(ETC) system is an important component of the intelligent transportation systems(ITS).5.8 GHz band,the mainstream of the international standard of ETC,was adopted by the national specifications of China on ETC that promulgated in 2007.Principles and composition of 5.8 GHz ETC system were described based on domestic ETC standard,and the key technologies of 5.8 GHz ETC system were summarized and analyzed.Then future research and development orientation were pointed out.The aim of the paper is to provide reference for a further study in 5.8 GHz ETC technology.
