基于复杂网络的高速铁路运输服务网络重构模型

运用复杂网络理论,基于L空间构建了以列车数量、运行时间为权重的高速铁路运输服务网络(该网络中包括525个车站、2 666列列车).在此基础上,利用度、强度、介数等复杂网络评价指标对两种网络进行对比分析,明确两种网络的不同运输意义,节点在两种网络中的不同作用.然后,充分考虑高速铁路路网乘客出行特征,以城市枢纽为研究重点、以运行时间为权重重构我国高速铁路运输服务网络,对比重构前后复杂网络指标值的变化,重点分析网络重构前后的网络特征、典型枢纽的变化.最后,基于分析结果为城市枢纽的客运换乘组织和车站分工提出参考方案.

China High-speed Railway Transportation Network Reconfiguration Based on Complex Network Theory

Based on the complex network theory and L-space model, a high speed railway transport service network is constructed with the weight of the train number and the running time (the network consists of 525 stations and 2 666 trains). On this basis, the paper comparatively analyzes the two kinds of network and the role of junctions using complex network evaluation index factor of degree, strength and betweenness, and defines the different implications of two kinds of transport network. Then, fully considering the high-speed railway travel characteristics of Chinese passengers, the paper reconstructes China's high- speed railway transportation service network with the weight of the running time and hub city. And we focuses on analyzing the difference characteristics of the network and typical hub before and after the reconstruction using indexes of complex network. Finally, the reference scheme is proposed for the construction of the station division and the passenger transfer organization based on the analysis results.
