| 摘 要： | 在道路交通与轨道交通组成的多模式城市交通网络中,考虑路径出行时间的不确定性,对用户的交通模式与路径的选择行为进行分析,建立基于出行时问预算的多模式多类用户均衡交通分配模型,设计基于路径配流的求解算法.研究结果表明:该算法适用于路径费用不具备可加性的交通均衡模型的求解；交通需求、路网降级及用户所需的可靠度水平对交通模式及路径选择均具有显著影响；随着交通需求水平的提高或路网降级加剧,用户选择轨道交通出行的份额增加,且可靠度需求较高的用户选择轨道交通的份额增幅更高.

| Abstract: | The transportation mode and routes choice behaviors were investigated and analyzed considering the uncertainty of travel time in the multi-mode urban transportation network consisting of both roadway and railway.Based on travel time budget,a multi-mode and multi-class user equilibrium traffic assignment model was proposed.A path-based traffic assignment algorithm,which was suitable for non-additive feature of path cost,was designed to solve the traffic equilibrium model.The results show that the traffic dem... |
