基于Delphi和改进模糊层次分析法的自动检票闸机通行能力评价指标体系

Evaluation System for Gate Capacity in Urban Rail Traffic Based on Delphi and Improved FAHP

针对城市轨道交通车站出入口自动检票闸机评价指标涉及因素多、范围广,以交通供求关系为出发点,构建闸机通行能力评价指标集。采用Delphi法和改进模糊层次分析法(FAHP)集成的方法,筛选出闸机自身性能、数量、闸机位置、客流特征4个一级指标中的13个二级指标,构建城市轨道交通闸机通行能力评价指标体系。以北京地铁1号线复兴门站闸机组为例,计算影响闸机通行能力的多项指标,并重点分析闸机数量、乘客熟知程度和闸机故障率3个指标。实例验证结果表明,该评价体系能客观反映实际情况,具有较强的可操作性和实用性。

The evaluation index of gate capacity in urban rail transit involves a wide range and many factors.From the aspect of supply-demand relationship,an evaluation system for gate capacity of urban rail transit is constructed,which integrates Delphi method and the improved FAHP.Four first level indices and thirteen second level indices related to gate capacity are selected to form an evaluation index.Fuxingmen Station on Beijing metro Line 1 is taken as an example to computer the indices affecting the gate capacity,in which three indices of gate number,passenger familiarity and gate failure rate are emphasized.The research provesthat the evaluation system has strong operability and availability in reflecting the real conditions of the automatic fare gate.
