北京某地铁交通枢纽换乘大厅客流密度计算模型
Calculation model of passenger flow density in transfer hall of a subway transportation hub in Beijing
摘要：
针对北京某地铁交通枢纽换乘大厅3个典型季节客流量进行了实测分析。结果表明:客流量不受室外气象条件、季节性影响,与工作时间及周围办公、居住人口规模密切相关;换乘大厅任一时刻在室人数等于该时刻进入的客流量级数与离开的客流量级数之差。根据客流密度特征,按工作日和周末分别建立了换乘大厅客流密度一元线性回归模型,并分段给出了客流密度拟合公式,利用实测数据验证了该模型的正确性。
Abstract：
In this paper, the passenger flow in the transfer hall of a subway hub in Beijing in three typical seasons is measured and analysed. The results show that the passenger flow is not affected by outdoor meteorological conditions and seasonality, but is closely related to the work schedule and the size of the surrounding office and residential population. The number of passengers in the transfer hall at any moment is equal to the difference between the inflow and outflow of passenger flow series at that moment. According to the characteristics of passenger flow density, the univariate linear regression model of passenger flow density in the transfer hall is established according to working days and weekends, respectively, and the fitting formula of passenger flow density is given in sections. The model is verified by measured data.
