【摘要】 简要分析了交通广播、VMS及车载诱导等诱导模式的特点及其对出行者路径选择行为的影响,建立了不同诱导模式下出行费用的计算模型及多种诱导模式混合作用下的出行者路径选择模型,据此提出了相应的仿真方法。对4×4结点路网的仿真结果显示:1)各类交通信息能有效地缩短出行者的出行时间,IVS信息的效果更为显著;2)当系统中无其它诱导方式时,IVS的效果比有其它诱导方式时更为显著,且其效果随IVS安装率增加而降低,当存在其它诱导方式时,其效果与IVS安装率的关联不显著。更多还原

【Abstract】 The characteristics and influence of 3 guidance systems(broadcast, VMS and In-Vehicle system) on users’ behavior were analyzed to choose route and the travel-fee calculation models and the route choice model under the circumstance that more than one guidance systems worked simultaneously were constructed.The result of series simulations on 4×4 network shows:1) Traffic information can reduce travel time effectively and the information from IVS is the most effective.2) The result of simulation with or without other guidance systems besides IVS showed that the effect was more dramatic in the former situation and, furthermore, the effect will reduce with the increasing of equipment rate of IVS.While in the later situation, there’s no obvious relativity between the effect and equipment rate of IVS.更多还原
