关于Ⅱ型大城市轨道线网合理规模的研究

基于多个Ⅱ型大城市样本,结合传统轨道线网规模预测分析方法,总结归纳线网规模预测中可供参考的参数系统;并选取规模预测主要影响变量,基于主成分分析方法,形成一个能综合反应出行需求、线网覆盖及建设能力等多方面影响因素的复合指标,进而通过回归分析,建立适用于Ⅱ型大城市的多维度轨道线网规模预测模型。

Study on Reasonable Scale of Rail Line Network in II Type Large City

Based on a number of II type large city samples, combined with the traditional rail line network scale predictive analysis method, the parameter system available for reference in the scale prediction of rail line network is summarized and sorted out. The main influencing variable of scale is predicted. Based on the principal component analysis, a composite index able to comprehensively reflect the travel demand, line network coverage, construction capacity and other influencing factors is formed so as to establish the multi-dimensional rail line network scale prediction model suitable for II type large cities through regression analysis.
