摘要:
［目的］为科学设置闸机,改善其实际通行能力,以及减少行人异常停滞行为带来的拥挤风险，需对城市轨道交通车站闸机设施处行人停滞行为谱特征进行研究。［方法］利用视频轨迹追踪技术，采集城市轨道交通车站闸机设施处监控视频中的行人运动参数；确定行人停滞行为表征指标，从闸机类型、行人流及个体停滞行为三类要素构建了城市轨道交通车站闸机设施处行人停滞行为谱，并采用四分位差法确定行人停滞行为谱表征指标上下限阈值；对行人停滞行为起点至闸翼/闸杆中心的纵向距离和横向距离，以及行人停滞范围和停滞时间等4个表征指标的差异性进行了分析，并全面解析了不同闸机类型和不同行人流率下的行人停滞行为谱特征。［结果及结论］行人易在闸机设施正前方停滞，行人停滞行为起点至闸翼/闸杆中心的纵向距离远大于其横向距离；当行人流率为＞5~10人次/min时，行人停滞范围波动性最大；随着行人流量的增加，行人可用空间、停滞范围及停滞时间均减小。

［Objective］ To scientifically set up the ticket gate, improve its actual passing capacity, and reduce the congestion risk caused by abnormal stagnation of the passengers, it is necessary to study the characteristics of passenger stagnation behavior spectrum at the ticket gate in urban rail transit stations. ［Method］ The video trajectory tracking technology is used to collect the passengers′ moving data from the monitor video at the ticket gate of the urban rail transit station. The passenger stagnation behaviors are determined as the characterization indicators. The passenger stagnation behavior spectrum at the ticket gate in urban rail transit station is established from the three elements i.e. types of the ticket gate, passenger flow and individual stagnation behaviors, and the quartile difference method is used to determine the upper and lower threshold values of the above indicators. The differences of the four characterization indicators of passenger stagnation behaviors are analyzed, including longitudinal and lateral distances from the starting point of passenger stagnation behavior to the center of the gate wing/gate rod, stagnation range, and stagnation time. The characteristics of the stagnation behavior spectrum under different gate types and different passenger flow rate are fully explained and analyzed. ［Result & Conclusion］ Passengers tend to strand in front of the ticket gate, and the longitudinal distance from the stagnation starting point to the center of the gate wing/gate rod is much longer than its lateral distance. When the passenger flow rate is larger than 5~10 person times/min, the passenger stagnation range fluctuates the greatest. As the passenger flow increases, the available space for passengers, the stagnation range and the stagnation time decrease.
