摘　　要：面向路网交通路况信息的采集、融合、发布及实时更新问题,提出了一种基于车载自组网技术,可自动采集、传播和动态生成路网实时交通路况信息的智能化车载交通信息系统,进而构建了相应的系统模型.该系统无需集中式交通信息系统相关设施,直接利用路网各路段行驶车辆的自身资源及车载自组网通信技术,实现交通路况信息的实时采集、自主传播及整个路网交通拥堵信息的自动生成与动态更新功能,并通过车载终端供驾驶员实时参考.In order to solve the problem of collection, integrating, transmitting and updating of traffic information in the road network, this paper studies and puts forward an intelligent vehicular traffic information system for automatic collection and generating of real-time traffic information in the road network based on the technology of VANET, and builds corresponding mathematical models of system. This system can realize the function of real-time collection and dynamic transmitting of traffic information in every road section by directly using the vehicles which travel on every road section in the road network and the existing information broadcasting technology of VANET and with no need for fixed facilities for collection, processing and transmitting of traffic information, and thus the real-time traffic information of the whole network is generated and updated, and it can provide drivers with reference through vehicular electronic map.
