Note: (1) NT_LOS indicates the number of sample points whose worst LOS of trains is A/B/C/D/E/F, respectively. (2) NS_TP indicates the number of sample points in the beginning and ending periods (5 : 00–6 : 00, 23 : 00–24 : 00)/morning peak (7 : 00–9 : 00)/evening peak (17 : 30–19 : 30)/flat peak (other periods), respectively.
