【摘要】：轨道交通方式因其具有舒适、安全、准时的特点而受到乘客的推崇,但受限于其在建设过程中因建设成本高等问题而不能提供门到门的服务。接驳公交作为轨道交通的延伸,可以为乘客提供灵活性更强、覆盖面更广的服务,同时接驳公交系统中最重要的组成部分—接驳公交线网设计问题越来越受到人民的关注。目前对于接驳公交线网设计问题的研究视角主要是从接驳公交系统的内部要素入手,研究系统内部要素以及各内部要素间的相互关系;有关接驳公交和轨道交通之间的协调关系的研究则相对缺乏。接驳公交和轨道交通之间的协调不仅可以提高轨道交通—接驳公交系统的效率,从而提高系统的服务水平;还可以完善轨道交通—接驳公交系统的一体化整合,降低乘客的出行时间成本。针对接驳公交线网设计问题,首先,论文基于轨道交通和接驳公交的协调理论,构建以乘客出行成本和运营商成本之和最小为优化目标,以线路长度、线路能力以及轨道交通与接驳公交之间的频率存在整数协调的关系为约束条件的接驳公交线网设计模型。其次,通过设计算例,采用Lingo数学优化软件对所构建的模型进行验证,证明了模型的准确性、有效性。再次,对模型中的参数进行灵敏度分析,分析结果显示:一、有协调时的系统总成本会增加,但乘客的出行时间成本会降低;二、协调情况下,系统总成本会随单位公交运营成本、乘客乘车时间成本、乘客候车时间成本、客流量、轨道乘客乘车成本的增加而线性增加,随接驳公交速度、轨道运营频率、轨道站点增加而减小。最后,采用遗传算法对所设计的算例进行了求解,通过比较这两种算法的精确度、运算效率以及适应算例的大小发现,遗传算法对于求解模型具有更大的优势。接驳公交与轨道交通的协调运行,一方面可以使接驳公交吸引更多的乘客来乘坐公共交通,减少小汽车的出行量,对环境起到很大的保护作用;另一方面对公共交通的发展有推动作用,形成一种良性的公共交通发展循环,促进公交一体化发展,提高了公交的竞争力和吸引力。
[Abstract]:Rail transit is highly praised by passengers because of its comfort, safety and punctuality, but it can not provide door-to-door service due to the high cost in the construction process. As an extension of rail transit, bus connection can provide passengers with more flexible and more extensive services. At the same time, the design of bus connection network, the most important component of bus system, has been paid more and more attention by people. At present, the research perspective of bus network design is mainly from the internal elements of bus connection system, the internal elements of the system and the relationship between the internal elements; The research on the coordination relationship between bus and rail transit is relatively lacking. The coordination between rail transit and rail transit can not only improve the efficiency of rail transit and transit system, thus improve the service level of the system, but also improve the integration of rail transit and transit system. Reduce travel time costs for passengers. To solve the problem of bus network design, firstly, based on the coordination theory of rail transit and bus connection, the paper constructs the minimum of passenger travel cost and operator cost as the optimization goal and the length of the line. The design model of the bus network is based on the integer coordination between the line capacity and the frequency between the rail transit and the bus. Secondly, the Lingo mathematical optimization software is used to verify the model, which proves the accuracy and validity of the model. Thirdly, the sensitivity analysis of the parameters in the model shows that: first, the total cost of the system will increase when there is coordination, but the travel time cost of passengers will decrease; second, in the case of coordination, The total cost of the system will increase linearly with the increase of unit bus operation cost, passenger travel time cost, passenger waiting time cost, passenger flow, rail passenger ride cost. Track stations increase and decrease. Finally, genetic algorithm is used to solve the designed examples. By comparing the accuracy, efficiency and size of the two algorithms, it is found that the genetic algorithm has a greater advantage in solving the model. The coordinated operation of bus and rail transit, on the one hand, can attract more passengers to take the public transport, reduce the number of cars, and play a great role in protecting the environment; On the other hand, it can promote the development of public transport, form a benign cycle of public transport development, promote the integration of public transport, and improve the competitiveness and attraction of public transport.
