摘要
分析了一体化公交网络的交通特性,基于一体化公交出行的路径特点,研究了公交出行时间与出行费用因素对出行阻抗的影响。考虑人流密度对步行速度的影响以及出行费用与时间的换算关系,将公交出行的路段阻抗、节点阻抗与费用阻抗统一换算为时间,建立了一体化公交网络的出行阻抗函数。利用Wardrop均衡原理,建立了一体化公交网络的均衡配流模型,并通过FW算法对配流模型进行求解。计算结果表明:当地面公交线路长度与轨道交通长度分别为57.3、16.2km时,轨道交通线路输送的客流量占总客运量的65.4%,通过换乘进入轨道交通系统的客流量达55.4%。构建合理的一体化公交网络能降低乘客出行总阻抗,提高公交系统运输效率。
The traffic characteristics of integrated transit network were analyzed, the impacts of trip time and cost on trip impedances were studied based on the path features of integrated transit network. By considering the impact of passenger flow density on walking speed and the conversion relation between travel cost and time, the section impedance, node impedance and cost impedance were transformed to time, and the trip impedance function of integrated transit network was set up. By using Wardrop equilibrium theory, an equilibrium assignment model was established, and the model was solved according to FW algorithm. Computation result indicates that when the lengths of bus transit and rail transit are 57. 3, 16. 2 km respectively, the ratio of passenger flow volume by rail transit and total passenger flow volume is 65. 4;, and 55. 40//00 passengers get access to rail transit system through transfer. So by constructing reasonable integrated transit network, the total trip impedance reduces and the transportation efficiency of transit network improves. 4 tabs, 5 figs, 18 refs.
