摘要
定性与定量分析相结合,对城市轨道交通线网规模匡算模型进行研究。运用结构化模型方法,建立了影响城市轨道交通线网规模因素的多级递阶结构图。分析了现有模型的不足,选取多级递阶结构图中的独立且较易量化的因素,运用逐步线性回归方法,建立了影响城市轨道交通线网规模的多因素模型。和现有模型相比,该模型较全面地反映各因素对城市轨道交通线网规模的影响。结合重庆市交通情况进行了实证研究,认为重庆市2020年轨道交通线网规模为348-385 km较为适宜。
A model of urban rail transit network scale was discussed based on qualitative analysis and quantitative analysis. The hierarchy figure of factors, which affected urban railway transit network scale, was established by the structure model method in system engineering. The shortcomings of existing models were analyzed. Some independent factors of the figure were selected to construct a multi-factor model by stepwise linear regression. Compared with the existing models, this model can reflect almost every factor＇s influence on the rapid rail transit network scale. At last, with Chongqing as an example, it is appropriate for Cbongqing to have an urban rail transit network scale of 348- 385 km by the year 2020.
