基于DSRC的ITS电子收费系统研究

DSRC-Based research on electronic toll collection system in the ITS architecture

电子收费系统 ( ETC,Electronic Toll System )是智能交通系统 ( ITS,IntelligentTransportation System)体系结构中一个重要的组成部分 ,在国外有着广泛的应用 ,也是 ITS体系中发展较为成熟的技术。把联网 ETC系统置于 ITS体系中加以研究 ,分析了电子收费系统的结构组成、数据流动模型、资金在银行系统的流动模型和与 ITS其它子系统的接口模型。通过 ITS数据通信协议 ( TCIP,Transportation Communication for ITSProtocol) ,可以充分利用 ETC信息 ,实现信息与 ITS体系中其它子系统共享。同时实现各个 ETC系统之间的协同工作 ,提出以专用短程通信 ( DSRC,Dedicated Short Range Communication)技术为基础的实现策略。最后对系统实现的关键技术加以说明。

ETC system is an important part in the ITS architecture,which is broadly used overseas,and it is a comparatively mature application.This article is to research the ETC system based on the ITS architecture,and to analyze its structure,the modal of data flow and the modal of financing flow in the clearing bank system and between other ITS subsystems.The subsystems can share the vehicle information with ETC system through the TCIP protocol.The article also focuses on the DSRC technology in order to realize the interoperability of the respective ETC systems.In the end,the article expatiates on some technologies of the implementation of ETC system.
