专用短程通信协议(DSRC)是为适应智能交通系统(ITS)的发展而专门制定的通信协议,它为车载单元与路边流量采集器之间提供通信链路,以实现交通流量信息的实时采集和发布。文中讨论DSRC通信协议的总体结构和特征、应用系统的组成,以及该协议在智能交通中的主要应用。
Dedicated short-range communication protocol (DSRC) is a communication protocol specially developed to adapt to the development of Intelligent Transportation Systems (ITS). It provides a communication link between vehicle-mounted units and roadside traffic collectors in order to achieve real-time traffic traffic information collection And released. This article discusses the overall structure and characteristics of the DSRC communication protocol, the composition of the application system, and the main applications of the protocol in intelligent transportation.
