地铁换乘站交通功能评价指标体系

Index evaluation system for transportation function of metro transfer station

针对地铁换乘站系统评价难题,建立了地铁换乘站交通功能评价指标体系,提出了各项指标的定义、计算方法与评分标准,构建了基于层次分析法的综合指标评价方法并探讨了权重系数,应用南京地铁7个换乘站开展算例研究,验证指标体系的有效性与实用价值。结果表明:建立的地铁换乘站交通功能评价指标体系能准确反映车站的现状问题,根据指标评分相似度可对车站进行归类,同类车站的共同特征表征明显;采用判断矩阵确定的指标权重系数满足一致性检验,得到的一级指标评分及总评分能够实现对车站整体状况的综合性评价。最后以柳洲东路站为例对车站评价结果提出方案优化建议,证实了成果的应用价值。

Aiming at the systematic evaluation problem of metro transfer stations,an index evaluation system is established for the transportation function of metro transfer stations.The definition,calculation method,and scoring standard for each index are proposed.Moreover,a comprehensive index evaluation method based on the analytic hierarchy process is constructed,and the weight coefficient is discussed.A case study is conducted using seven transfer stations of Nanjing metro to verify the validity and practicality of the proposed index evaluation system.Results show that the second-level indicators can accurately reflect the current situation of the stations,and the stations can be classified based on the similarity of the index scores.Similar stations exhibit common characteristics.The index weight coefficient determined using the judgment matrix satisfies the consistency test,and the obtained first-level index score and total score can comprehensively evaluate the overall status of the station.Finally,considering the Liuzhoudonglu station as an example,an optimization of the station evaluation results is proposed,which confirms the applicability of the system.
