摘　　要：不依赖固定站点而更具有灵活性的浮动汽车共享(free-floating car-sharing,FFC)模式逐渐受到关注.为了评估该新兴出行方式在多模式交通系统中的影响力,基于融合浮动共享汽车的多状态超网络模型,提出了考虑共享汽车预约需求的动态活动-出行配流模型,刻画了预约/未预约共享汽车的需求与共享汽车供给之间的动态交互过程.另外,模型综合考虑了出行者的有限理性决策行为以及出行者在活动-出行选择集、时间与金钱价值方面的异质性.通过算例分析,结果表明浮动共享汽车在交通系统中的影响力受到其分布、规模与价格等供给因素以及出行者有限理性行为的影响.Being more flexible than station-based car-sharing programs,free-floating car-sharing(FFC)has received increasing attention.To capture the influence of FFC on multi-modal urban mobility,this study proposes a dynamic activity-travel assignment model which considers the reserving demand for shared cars(SC).By the representation of extended multi-state super-network with SC,the dynamic interactions between the supply and the demand with/without reservation of SCs are formulated.Moreover,travelers’bounded rationality and traveler heterogeneity on activity-travel sets and value of time/money are taken into account.A numerical example demonstrates that the influence of FFC on the multi-modal traffic system is constrained by initial distribution,fleet size and price of SC from the supply side and bounded rational behavior of travelers from the demand side.
