摘要
为评估大城市夜间公交网络结构的合理性,识别其核心区域,使用社会网络分析法(SNA)对南京市夜间公交网络展开研究。首先,收集南京市夜间公交线路及换乘信息,从“社会关系”角度构建夜间公交社会网络邻接矩阵;随后,对夜间公交网络进行中心性分析和凝聚子群分析,获取其中存在的个体信息和结构信息,研究结果展示了夜间公交线路的重要度分布以及网络核心区域。最后,结合夜间出行需求的特点,针对夜间公交的运行效率和服务水平,从线路布局、核心线路群的设置等方面提出了优化夜间公交网络的建议,从而推动“夜间出行圈”的构筑。
To evaluate the rationality of the nighttime bus network structure in large cities and identify its core areas,this article uses the Social Network Analysis(SNA)method to study the nighttime bus network in Nanjing.Firstly,the paper collects information on nighttime bus routes and transfers in Nanjing,and draw a social network adjacency matrix for nighttime buses from the perspective of“social relationships”;Subsequently,centrality analysis and cohesive subgroup analysis were conducted on the nighttime bus network to obtain individual and structural information.The research results showed the importance distribution of nighttime bus routes and the core areas of the network.Finally,based on the characteristics of nighttime travel demand,suggestions are proposed to optimize the nighttime bus network from the aspects of route layout,core routes group setting,etc.,in order to improve the operational efficiency and service level of the nighttime bus network,thus promote the construction of the“nighttime travel circle”.
