摘要
【目标】模块化公交为促进公交可持续发展提供了新思路。本研究旨在引入模块化公交这一公交新形式,运用其模块灵活拆分组合、途中无缝换乘以消除换乘等待时间的优势进行公交运行线路优化。【方法】首先,结合传统公交的主要运营问题,对比分析传统公交站内换乘和模块化公交途中无缝换乘的区别,总结得到模块化公交的运营优势及运行线路设计重点;其次,将模块化公交作为研究对象,以降低运营成本和乘客的广义旅行成本为双目标,构建考虑乘客路径分配的模块化公交运行线路设计模型;然后,在既定运行线路候选集、路径候选集和出行需求的条件下,运用模型获得模块化公交的运行线路设计和与之相匹配的乘客路径分配方案;最后,采用简单交通网络进行算例分析,并通过改变运行线路长度限制、调整模型目标函数各部分权重,对模型进行灵敏度分析。【结果】模型能够高效产生合理的运行线路设计和乘客路径分配方案,计算时间控制在秒级,乘客换乘次数控制在2次以内,且对参数变化具有良好适应性。【结论】研究所得的运行线路设计和乘客路径分配方案有助于降低模块化公交运营成本和乘客的广义旅行成本,具有实际应用价值。
[Objective]Modular buses provide novel approaches to promoting the sustainable development of public transportation.This study aims to introduce the modular buses,i.e.,a new form of public transport.It uses the advantages of flexible module coupling and decoupling,as well as the seamless transfer,to eliminate the transfer waiting time and optimize the bus route design.[Method]First,the main operational issues of conventional bus systems were examined.The study compared traditional bus in-station transfer with modular bus seamless transfer.It summarized the operational advantages of modular buses,and identified the key considerations for path design.Second,a line design model was developed with modular buses as the study object.With the dual objective of reducing operating costs and passengers’generalized travel costs,a modular bus operation route design model considering passenger path assignment was constructed. Third, in the conditions of established set of running routes, set of path candidates and travel demand, the model was applied to obtain the modular bus running design and the corresponding passenger path allocation scheme. Finally, the example analysis was carried out by adopting a simple traffic network;and the sensitivity analysis on the model was carried out by changing the line length limit and adjusting the weight of each part of the objective function of model. [ Result] The proposed model produces reasonable line designs and passenger path assignments. The computation time is within seconds. The passenger transfers are kept within two times per trip. [ Conclusion] The operating lines design and passenger paths assignment obtained with the proposed model are helpful for modular bus to reduce the operation cost and generalized travel cost at the same time, which has the practical application values.
