高速铁路网络系统中心性的车站综合分级方法

应用系统中心性理论,综合考虑高速铁路的基础设施网络、车流网络及客流分布特征,构建了高速铁路车站系统中心性综合分级方法.在充分考虑高速铁路运输网络特征的基础上,对既有系统理论中的中心性指标进行改进,并利用实际的铁路客流数据确定合理的系统中心性计算方法.利用综合评价分级方法对我国高速铁路路网的525个车站分级评价,明确每个等级车站的数值分级依据,结合路网发展特征阐述每个等级车站的路网演化意义与运输定位.分级结果对于我国高速铁路服务网络明确车站分工、提高路网运输效率有指导意义.

Stations classification method based on system centrality for high-speed railway network

Applying the system centrality theory and considering the infrastructure network of high-speed railway,the traffic network and characteristics of passenger flow distribution,a method of the comprehensive grading system for the high speed railway station is constructed in this paper.Firstly,the centrality index parameters are improved using the node characteristics of high-speed railway transportation network and reasonable calculation method of system centrality is put forward using actual passenger flow data.Secondly,525 stations of high-speed railway network of China are assessed and graded using the comprehensive evaluation method.Finally,this paper has defined classification of each level station and explained the significance of the gradual development and the transportation position combined with the development characteristics of the network.The results have great significance to clarify the labor division and improve the efficiency of railway transportation for Chinese high-speed railway service network.
