Most large transportation terminals in large cities have not only transportation function but also commercial function. Then, most large transportation terminals have three dimensional structures, which force travelers to three dimensional behaviors. This study aims to develop a three dimensional route choice model for pedestrians in large transportation terminals, based on observational survey.
In order to explain such pedestrian behavior, this study adopts two stages of process. In the first stage, location choice models in order to find the point of up and down are developed, and the other models for estimation of route choice behavior in ground and under ground level respectively in the second stage. Combining the models, this study proposes a method to estimate pedestrian route choice behavior in a large scale transportation terminal in three dimensional space.
