为研究地铁站闸机使用不均衡对闸机通过能力的影响，以西安地铁2号线刷卡数据与车站周边土地利用结构为基础，对地铁车站乘客的闸机选择行为进行研究，使用最优尺度回归模型，定量分析影响闸机通过能力的因素。结果显示，闸机布置方向、用户数量、闸机编组数量、车站周边用地属性对闸机通过能力有显著影响。平均修正系数，平行式闸机组比垂直式闸机组高0.301；随着编组数量增加，闸机组通过能力折损程度呈现阶梯式上升；垂直式闸机组通过能力，对外交通枢纽、居住区、开发区车站明显高于商业区、混合区车站。据此给出不同情况下闸机组通过能力的修正系数及计算公式，并提出闸机布置建议供新线站厅建设参考。

To analyze the influence of gate imbalance on the passing capacity of gates, this study analyzes the gate selection behavior of passengers. Based on land use structure and data on the entry and exit station of Xi’an Metro Line 2, an optimal scale regression model is adopted to explore the significant determinants influencing the unbalanced utilization of automatic ticket gates. The result indicates that the positional relationships between gates and passenger walking direction, passenger flow intensity, gate configuration quantities, and land use structure have significant effects on the unbalanced utilization of automatic gates and indicate that the capacity reduction of the gate has a stepwise rise with an increase in configuration quantity. Furthermore, this paper provides the gate group capacity adjustment coefficient for each case, as well as some suggestions regarding gate group configurations to improve automatic gate capacity.
