Abstract

<p>In the public transit navigator system, the user’s travel demands, such as the requested departure place and destination place and what time to move, are recorded as log data. However, the log data don’t include information of user’s attributes and their travel purpose. Therefore, it is not possible to clarify what kind of people travel for what purpose from the log data. This study analyzes the user’s attributes and their travel purpose from the relationship between travel demands on the log data and characteristics around railway station. Specifically, this study uses the log data of “NAVITIME”, which is a public transit navigator system introduced in Japan, and expresses travel demands. Characteristics around railway station are expressed by population data and facility’s location data. Then, this study constructs the model by using Bayesian tobit quantile regression with adaptive lasso penalty. From the estimation results of the model, it is confirmed that inhabitants and tourists use public transit navigator system for nonsteady travel purpose such as shopping, attending a hospital and sightseeing.</p>
