【摘要】：城市公共交通系统包括轨道交通、快速公交BRT、地面公交等多种模式,多种模式的整合优化对于发挥公交线网整体运输效率具有重要的意义.针对方格型路网布局结构,提出理想的公交线网布局结构,将多等级公交线路与公交换乘枢纽结合,表现为主线、辅线和补充线的组织形式.该线网结构的关键设计参数包括公交主线间距、快线线路站距和交通分区大小.从出行者、运营企业和政府管理者角度出发,分别建立关键设计参数优化模型,在特定的城市交通背景条件下,利用数值试验方法对该模型进行求解,给出不同出行距离条件下关键设计参数的建议值,其结果可以为大城市多模式公交线路整合规划提供参考.
[Abstract]:Urban public transport system includes rail transit, bus rapid transit (BRT), ground transit, and so on. The integration and optimization of various modes is of great significance for giving full play to the overall transport efficiency of public transport network. The ideal layout structure of bus network is put forward, which combines the multi-grade bus line with the bus transfer hub. It is shown as the main line, the auxiliary line and the supplementary line. The key design parameters of the network include the distance between the bus lines. From the point of view of travelers, operators and government administrators, the optimization models of key design parameters are established respectively, under specific urban traffic background conditions. The numerical test method is used to solve the model and the suggested values of key design parameters under different travel distances are given. The results can provide a reference for the integrated planning of multi-mode bus routes in large cities.
