Abstract: For the problems of information concussion generated during a period of time when the traffic information service of urban road released, the driver stimulus-response model based on the strategy of urban dynamic traffic induction information to eliminate information concussion and help drivers select the optional path was proposed, which analyzed the impact of traffic guidance induction information on the drivers’ path option, combining with drivers’ travel behavior. The proposed model took the release of traffic information service as the quantity of stimulus and the change of road traffic load as the quantity of reacting. According to the analysis of simulation example, the dynamic region of traffic information service was ensured. Researches show that the proposed method could significantly reduce the traffic information concussion, which has strong practicability in improving the utilization efficiency of urban road network.

摘要： 针对城市道路交通信息发布时产生的信息震荡问题，以消除信息震荡、帮助驾驶员选择最优路径为目的，结合驾驶员的出行行为分析了交通诱导信息对驾驶员选择行为的影响，将交通信息发布变化量作为刺激量、路段交通负荷度变化量作为反应量，构造了基于动态交通诱导信息策略的驾驶员刺激-反应模型，通过仿真算例确定了交通信息发布的动态区间。研究表明：该方法能够有效减少交通信息震荡，对改善城市路网的使用效益具有较强的实用性。
