【摘要】：研究M-M乘客需求模式下接运公交网络的设计与优化问题.首先,根据每个公交站单位时间的乘客需求确定经过它的公交线路数量;其次,设计了一种逆向径向扫描算法,并应用它生成了满足条件约束及设计要求的基本接运公交线路集;再次,引入线路优化算法整合不合理线路,并通过插入操作,将不合理线路上的公交站重新安置到合理线路的最佳位置;最后,结合一个实际问题,通过接运线路数量、总线路长度、平均线路频率,以及公交使用者花费和公交运营者花费等指标,比较分析了优化前后接运公交网络的整体性能.结果表明,经过优化的接运公交网络不仅线路长度适中、结构合理,而且能够更好地平衡公交使用者和公交运营者的利益,降低系统的总费用,所以本文提出的逆向径向扫描算法和线路优化算法是可行的,也是有效的.
[Abstract]:This paper studies the design and optimization of transit network in M-M passenger demand mode. First of all, according to the passenger demand per unit time of each bus station, the number of bus lines passing through it is determined. Secondly, a reverse radial scanning algorithm is designed. It is used to generate a set of basic bus lines that meet the requirements of conditional constraints and design. Thirdly, the line optimization algorithm is introduced to integrate unreasonable lines, and the insertion operation is carried out. Relocation of bus stations on unreasonable lines to the optimal location of reasonable lines; finally, combining with a practical problem, by connecting the number of lines, the total length of lines, and the average line frequency, The overall performance of bus network before and after optimization is compared and analyzed, as well as the cost of bus users and operators. The results show that the optimized bus network not only has moderate length and reasonable structure, but also can better balance the interests of bus users and operators, and reduce the total cost of the system. So the inverse radial scanning algorithm and the line optimization algorithm proposed in this paper are feasible and effective.
