中文摘要：
城市快速公交网络性质研究对其规划建设、运营管理具有重要意义.本文将复杂网络理论研究领域由传统的轨道交通扩展到整个城市快速公交,并针对L空间度值物理意义模糊、路径选择实际意义匮乏等缺陷,提出了新型S空间模型构建方法.以常州BRT系统为例,采用新型建模方法,用计算度值、聚类系数、路径长度等特征指标分析了城市快速公交网络整体性能.继而采用效益费用比指标,比较其各支线优化方案效用,为资源限制条件下支线优化方案的选择提供建议;最后通过比较城市快速公交骨架网络及常规公交衔接下的快速公交网络的鲁棒性,验证了城市快速公交与常规公交一体化衔接规划的重要性.
英文摘要：
Exploring the performance of urban rapid transit network has certain significance on its planning,construction and operation.This paper expands the research field of complex network theory from rail transit to the whole urban rapid transit.It proposes the Space S modeling approach to overcome the practical significance problems with the features and path selecting method in the Space L.Taking the Changzhou BRT as an example,the paper analyzes the whole performance of urban rapid transit respectively in Space P and Space L using the indexes as calculating degree,clustering coefficient,path length.By analyzing the branches＇ effectiveness with FBCR（Financial Benefit-Cost Ratio）,this paper presents a branches＇ selection method.Through the robustness comparison between urban rapid transit network and bus transit,the importance of the integration of the two modes is thus proved.
