摘　　要：为满足出行者对实时交通信息的需求,在已获得交通信息的基础上,结合出行者需求的个性化、多样化等特点,研究了实时交通信息的短消息动态发布模式。以通用SMIP协议为承载,采用自定义的应用层协议;设计伺服和推送两种发布服务方式,达到更好的手机终端与交通信息平台之间的信息协同效果。最后,以Java开源软件为平台开发交通信息的短消息动态发布子系统,使已有交通信息发布系统的基本功能得到进一步的拓展。Based on the advanced Traffic Data Collection System and combined with individuation and diversification demand of travelers, the dynamic short message publishing mode for the city real-time traffic information has been studied in order to meet the travelers＇ demands for traffic information. In view of Short Message Gateway Interface Protocol, employing self-defining application layer protocol, as well as the de- signed two serving ways of publishing which include servo and push modes, a better cooperation performance of mobile phone terminal and transportation information platform is exhibited. The real-time dynamic short message publishing system, which was built on the base of the Java -open source software, extends the existing basic functions of Traffic Information Publishing System.
