摘要
通过对南京地铁2号线新街口站特定车门的实际观测和统计分析,发现单个车门客流总速度的频次分布符合正态分布特性,其速度均值接近于车门额定通行能力;上车客流与下车客流的速度比与人数比之间存在线性关系,并建立了线性数学模型。实际检测表明,该模型较好地反映了对冲客流中客流人数对速度分布的主要影响作用。
We observed a special train gate in XinJiekou Station of Nanjing metro line 2. The statistical analysis data slaowed that the frequency distribution of the total speed of the passenger flow up and down the gate conformed to the normal distribution. The average value of the speed was close to the rated traffic capacity of the gate. There was a linear relationship between the speed ratio and the number ratio of the passenger flow up the gate and down the gate. We established the linear mathematical model, and it accorded with the experimental data.
