北京南站客流分析

Analysis of Passenger Flow of Beijing South Station

通过对北京南站的实地调查,以第一手资料作为依据,使用matlab软件,用非线性最小二乘法拟合出了北京南站旅客提前到达时间(即旅客候车时间)的概率分布,结合列车时刻表,积分加总计算出南站的最高聚集人数,同时也调查得出了各种交通方式的分担率,为北京南站各类设施的评价提供依据。

Using the software Matlab on the firsthand data gathered from field investigation, the paper calculates the probability distribution of the lengths of waiting time for passengers at Beijing South Station through nonlinear least square fitting algorithm, which, together with the train departure-and-arrival schedule, enables the calculation of the passenger volume at the station at any moment. Using the foregoing method, the paper obtains the largest number of passengers simultaneously at the station and, through investigation, the percentage of different transport modes adopted, which can offer support to the evaluation of the facilities at the station.
