摘要
城市交通系统中,轨道交通与地面公交一体化是促进公共交通出行的有效措施。随着轨道交通网络日益扩大,既有接驳公交线路已无法满足乘客日益增长的通勤需求,且存在运营成本高、运行效率低等问题。轨道接驳公交线网规划的关键环节是如何优化选取接驳站点和接驳线路。为解决“双Y形”接驳公交线路共线段站点重复引发的资源浪费与乘客乘车时间过长的问题,引入了竞合理论的公交线路站点跳停优化方法,同时考虑乘客出行时间成本与公交企业运营成本两个优化目标,通过共线段重复站点数量以及线路在该站的客流量给出公交线路的竞合强度约束,建立公交线路共线段站点跳停优化模型,并以北京市公交IC卡数据为例采用NSGA-Ⅱ算法进行求解验证。结果表明:与既有停站方案相比,优化后的乘客在途时长降低了22.5%,公交企业运营成本降低了32.1%。研究结果可为增强接驳公交出行效率提供参考。
The integration of rail transit and ground buses is an effective approach for promoting public transportation in urban transportation systems. Owing to the increasing expansion of rail transit networks, the existing feeder bus lines can no longer satisfy the increasing demand for commuting, and problems such as high operating costs and low operating efficiency have emerged. Optimizing the selection connecting stations and routes is key to the planning of rail-connecting bus networks. In this study, to mitigate resource wastage and long passenger travel time caused by the duplication of stations in the common line section of the “double Y-shaped” feeder bus line, an optimization method of stopping and skipping bus lines based on competition theory is proposed. Additionally, the passenger travel time cost and the operating cost of the bus enterprise are reduced by optimizing the number of duplicated stations in the common line section and the number of passengers in the line at the station. The number of duplicated stops in the common line segment and the passenger flow at the stop provide the competing intensity constraints of the bus line, thus enabling a stop-hopping optimization model of the bus line's common line segment to be established. The model is validated using the bus IC card data of Beijing, China using the NSGA-Ⅱ algorithm as an example. The results show that, compared with the results of the existing stopping scheme, the optimized passenger on-travel time reduced by 22.5%, and the operating cost of the bus enterprise are reduced by 32.1%. This study provides targeted suggestions for enhancing the efficiency of feeder-bus travel.
