专用短程通信在智能交通系统中的应用

交通专用短程通信(Dedicated Short Range Communication,以下简称DSRC)是智能交通系统的基础,是专门应用于智能交通领域的一种短距离无线通信协议。它是车辆与路边设备进行单向或双向交互式通信的标准,将车辆和道路有机地连接起来。从而,交通控制中心可以通过与行驶车辆的数据通信实现对车辆的智能管理,同时车辆还能够接入交通信息网,使用信息网中的资源。本文研究了DSRC系统的三层体系结构,讲述了交通专用短程通信系统的软硬件实现方法,最后对DSRC系统研究意义进行了一定的分析。

The application of dedicated short range communication in intelligent transportation system

The DSRC protocol is a kind of short range wireless communication protocols,which is applied exclusively in the intelligence transportation field.It is a standard of interactive communication in the single or double directions between vehicle and roadside equipments.And with the help of this protocol,the roadside and vehicle unit are connected together.Thereby the transportation control center can manage the vehicle with the communication data of the driving vehicle.At the same time,the vehicle can connect into the transportation information network and use the information resources in the network.In this thesis the three-layer protocol system construction of DSRC has been researched,and it has researched the realization process of DSRC system both in software and hardware.Lastly,the significance of the DSRC system has been analyse.
