It is shown by analyzing the data collected in the transfer passage from Line No. 5 to Line No. 1 at Dongdan station, that
the probabilities of walking time of passengers follow Log-normal distribution and its expected value and standard deviation are affected remarkably by crowding. Next, equivalent distance of transferring is conceived considering the real distance of passage and different affections of facilities equipped along. Finally, regression analysis of data from 10 transferring passages shows that the expected value of passenger walking time is quadric to the equivalent distance of passage

As the passenger flow is increasing, subway station facilities have shown issues incompatible with such a growth.
