Time characteristic of input passenger in urban rail transit stations among high density residential areas

To describe the time characteristic of input passenger flow in urban rail transit stations among high density residential areas, the paper brings in the three concepts: peak hour, peak hour factor (PHF) and extra peak hour factor (EPHF). In the case of two typical stations (Hui-Long-Guan and North Tian-Tong-Yuan) in Beijing, it draws the main conclusions that the peak period lasts longer in Hui-Long-Guan than in North Tian-Tong-Yuan while the peak hour of Hui-Long-Guan lags 30 minutes on working days. Moreover, the average PHF of working days is as high as 0.38 in Hui-Long-Guan while 0.28 in North Tian-Tong-Yuan. However, the different reasons result in the low20min-EPHF in both of them on both working days and rest days.
