摘　　要：专用短程通信(DSRC)协议是智能交通系统领域内的重要基础通信协议,已广泛地应用于高速公路电子不停车收费(ETC)系统、城市路桥拥堵收费系统等智能运输系统中。它可为车-路,以及车-车之间提供可靠、高效的数据传输。文中参考欧洲CEN DSRC标准,针对DSRC系统中低速数据延迟响应的问题进行分析,给出了低速数据延迟响应几种可能的实现方法,以完善国标DSRC标准。同时,该方法可推广应用在基于专用短程通信协议的智能交通系统中。Dedicated Short-Range Communication （DSRC） is an important and basic communication protocol in In telligent Transportation Systems （ITS） area, which has been widely used in Intelligent Transportation Systems, such as highway electronic toll collection（ETC） system and city road and bridge congestion charge system, which provides reliable and efficient data transmission for vehicle-infrastructure communication and vehicle-vehicle communication. This paper, referring to the CEN DSRC standards, discusses the later response of low speed data in the DSRC protocol, and gives some methods to solve this problem in order to complete the GB DSRC standards. Meanwhile, this method can be used in the practical ITS system which is based on the DSRC protocol.
