Analysis of the Rule for Passenger Waiting Time at Lanzhou Station

Passenger waiting time decides the assembling degree at station waiting hall and is the basis for deciding the maximum assembling passengers number of station. By investigating at Lanzhou station, the rules of passenger waiting time for origin train and passing train are analyzed, and several distribution models of waiting time are obtained through curve fitting. Moreover, the characteristics and influence factors on passenger waiting time are analyzed by comparing with passenger waiting time at other railway stations. The results show that the rules of passenger waiting time at Lanzhou station obey the rational distribution and Gaussian distribution, the average waiting time at Lanzhou station is longer and coefficient of variance is bigger. Furthermore, the bulk arriving degree of passing train is higher and the passenger arriving time of origin train is earlier.
