轨道交通车站超高峰系数是反映车站高峰客流特征的关键指标之一，是城市轨道交通设施设计规模的重要依据。对超高峰系数的概念进行辨析，指出车站超高峰系数应为车站高峰小时内最大20min进出站客流量的小时当量与高峰小时进出站客流量的比值。据此，以北京市城市轨道交通车站为实例，对其超高峰系数进行综合分析，并提出了轨道交通车站超高峰系数的主要影响因素。结果表明，虽有约74%的轨道交通车站超高峰系数处于相关规范推荐值1.1-1.4区间，但另有26%的车站超高峰系数处于1.0-1.1区间，低于规范推荐最小值；车站周边用地性质、车站高峰小时进出站客流量及车站客流管控措施（限流）对车站超高峰系数的取值均会产生影响：就业类车站超高峰系数取较大值的可能性更高；高峰小时客流较小的车站，其超高峰系数往往偏大，而高峰客流规模超大型车站，其超高峰系数取值一般不超过1.2；此外轨道交通车站限流会降低其超高峰系数。

The station super-peak coefficient is one of the key indicators reflecting the characteristics of the station's peak passenger flow, and it is an important basis for the design of urban rail transit facilities. Discriminating the concept of the super-peak factor, the super-peak factor of a station should be the ratio of the maximum 20-minute passenger flow hourly equivalent during the peak hour of the station to the passenger flow entering and leaving the station during the peak hour. Then this paper comprehensively analyzes the super-peak coefficient of each station of Beijing urban rail transit, and puts forward the main influencing factors of the super-peak coefficient of rail transit stations. The results show that about 74% of urban rail transit stations have super peak coefficients in the recommended range of 1.1-1.4, and another 26% of stations have super peak coefficients in the range of 1.0-1.1, which is lower than the recommended value. The nature of the land around the station, the station entry and exit passenger volume during peak hours, and the passenger flow control measures (metro current limit) of the station all have an impact on the value of the super peak coefficient of the station. It is more likely that the over-peak coefficient of employment oriented station takes a larger value; the station with small passenger flow during peak hours tends to have a large over-peak coefficient, while the super-peak coefficient of ultra large peak passenger flow scale station generally does not exceed 1.2. In addition, the current limit of rail transit stations will reduce its super peak coefficient.
