基于复杂网络的公交线网可达性特征分析

Public Transportation Network Accessibility Analysis Based on Complex Network

文中利用复杂网络堆积公交线网的拓扑结构进行分析,建立公交可达性复杂网络模型,以南通市为例,计算度分布、聚类系数、站间平均换乘次数、关键点等,并将研究成果开发为基于GIS的公交线网可视化分析平台,清晰地展现线网重要站点与线路以及存在的问题,辅助公交线网规划与设计。

Based on complex network,the topological structure of bus network is analyzed in this paper. Complex network model of the bus accessibility in nantong city in china is set up,where degree distribution,clustering coefficient,standing between the average transfer times,key points,etc. are obtained. The research development of theory-oriented and visualized analysis based on GIS platform,clearly show line network stations and lines as well as the existing problems,and auxiliary bus network planning and design.
