摘要: 针对集中式交通信息系统存在的基础设施投资过大、信息处理过于集中,以及自主式交通信息系统较多侧重安全信息,而较少涉及路网拥堵信息的采集与发布等相关问题和不足,提出了一种基于车载自组网(VANET)、面向城市路网的自主式智能车载交通信息系统(IVTIS)及相应模型。为验证和评价IVTIS的合理性及有效性,基于交通仿真二次开发平台及相关评价指标,分别对路网拥堵信息的采集融合及动态传播效果进行了仿真评价,进而对路网车流量、信息传播丢包率对整体传播效果的影响进行了综合分析。仿真结果表明:IVTIS模型较为合理,其在面向城市路网的拥堵信息实时采集与动态传播方面表现出良好的自主性及扩散传播效果。

Abstract: The concentrated traffic information system had problems, such as over-size investment on infrastructure and over-concentrated data processing. The self-organizing traffic information system focused more on the information safety and focused less on the collection and release of congestion information of the road network. According to the conditions mentioned above, a VANET-based and urban road network-oriented self-organizing intelligent vehicular traffic information system (IVTIS) pattern and model was proposed. Road network congestion information collection, integration and dynamic disseminating effects were simulated and analyzed comprehensively based on the secondary development platform of VISSIM and relative evaluation indexes. Moreover, impacts of vehicle inflow and information packet loss rate during transmitting on the congestion information spread within the whole road network were compared and evaluated. The simulation results confirm not only the rationality and feasibility of the proposed IVTIS model, but also its satisfactory performance in automatic real-time collection and dynamic spreading of congestion information within the whole urban road network.

Key words: traffic engineering, intelligent vehicular traffic information system(IVTIS), congestion information, autonomous collection, autonomous transmission
