中文摘要：

为提升公交系统运输效能与服务质量,并针对以往仅从网络流量或土地利用单一角度求解枢纽最优布局问题的局限性,从解析枢纽＂服务分区＂特性入手,建立＂枢纽服务分区、线路干支分离＂的城市常规公交枢纽布局优化模型;进而基于网络解构思想简化模型复杂度、探索最优求解算法并加以实现;最后结合苏州工业园区实际案例验证模型与算法普适性,并对模型的关键参数进行灵敏度分析.结果表明：通过引入＂服务子区＂概念可以从系统最优角度实现交通需求与土地利用互动的数学表述,因而可更科学客观地反映城市公共交通网络服务的实际特性与公交枢纽规划实践.

英文摘要：

In response to the need of promoting transport efficiency and service quality for urban transit systems, this paper proposes an optimal location model for urban transit transfer centers by integrating the concepts of＂service zoning and route classifying＂. It explicitly takes into account that the serving capacity of transit transfer centers will be affected by travel demand distribution, land use, and transit network topology. An efficient reformulation was developed to solve the proposed model and yield the global optimal solution for large-scale real-world applications. The model was successfully applied to optimize the transit transfer center locations in Suzhou Industrial Park, China, with the results of significantly improving the system performance and effectively capturing the interaction between travel demand and land use.
