摘　　要：动态交通信息系统是智能交通系统中重要的组成部分,作为一种新兴的车辆间无线通信网络技术,车载自组网可有效提高高速行驶车辆间的信息共享能力。文章阐述利用基于车载自组网的交通信息采集和交通事件协同检测算法、大规模海量交通信息的分布式组织和实时处理方法、基于位置的交通信息分发协议等技术,构建一个动态交通信息系统,实现改进交通信息系统中的事件检测的准确性和实时性,提高大规模交通信息处理的实时性,改善交通信息分发的针对性。A dynamic traffic information system is an essential component of an intelligent transportation system. Vehicular ad hoc networking （VANET） is a new wireless technique that can be used to improve information sharing between vehicles moving at high speed. VANET techniques that can be used in a dynamic traffic information system include cooperative detection algorithm for traffic events and information based on VANET, distributed real-time processing of mass traffic information, and position-based traffic data delivery protocols. These improve the accuracy and immediacy of traffic event detection, ensure real-time processing of mass traffic data, and ensure traffic data is delivered appropriately.
