Vehicle choice behavior of railroad passengers was modeled using five essential factors. Using the actual data of passengers, unknown parameters were estimated, and the accuracy of the model was confirmed. From the estimated values of parameters, we discussed the degree of influence of each factor on vehicle choice behavior that varies according to travel direction and the time of day. Finally, we estimated the spatiotemporal distribution of passengers on each platform, and discussed the time loss, which will be observed in the process of passengers' getting on and off when they are distributing unevenly on platforms according to their preference.
