基于客流加载的城市轨道交通网络关键点分析

Analysis of key points of urban rail transit network based on passenger flow loading

在城市轨道交通网络化运营中,节点重要度的有效评估对优化网络结构、提高网络运营效率具有十分重要的意义。以网络节点为研究对象,改进经典space L模型,考虑运用同异站台换乘构建网络拓扑结构,建立客流均衡分配模型,基于复杂网络理论,提出网络客流加载条件下车站节点重要度的3个评价指标,分析各指标与实际客流的相关性,得到节点重要度的综合测算模型。以北京地铁网络进行实例分析,结果表明客流加载条件下的节点重要度更符合地铁网络的运营实际。

In the urban rail transit network operation,the effective evaluation of node importance is of great significance for optimizing the network structure and improving the efficiency of network operation.Taking the network node as the research object,the classic space L model is improved,the network topology is constructed by considering the transfer of the same platform,and the equilibrium distribution model of passenger flow is established.Based on the complex network theory,three evaluation indexes of station node importance under the condition of network passenger flow loading are proposed.This paper analyzes the correlation between each indicator and the actual passenger flow,and obtains a comprehensive measurement model of node importance.The example analysis of the Beijing subway network shows that the importance of nodes under the conditions of passenger flow loading is more in line with the actual operation of the subway network.
