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。

Urban public transit consists of multiple transit modes, such as railway, BRT and bus. The integration of multi-class urban public transit lines is very important to achieve a more efficient transit system. To the grid road network, this paper presents an urban public transport network structure integrating multi-class public transit lines and transfer hubs. The urban public transit network structure consists of primary routes, feeder routes and accessorial route. Primary routes spacing, MRT stops spacing and the size of transfer hub service zone are the key design variables. From the points of view of the traveler, operator and authority respectively, the optimization objective functions for the key design variables are formulated, and the numerical analysis is carried out to find the optimal solution. For the given input parameters values, the recommended values of the key design variables are put forward. The results can provide a reference for the integration planning of multi modal transit lines for the big city.
