A simple model to express long-distance travel demand across prefectural borders is the "gravity model." This model can explain the basic distribution of inter-prefectural travel based on the scale of origin and destination and the distance (travel cost). However, there are movements associated with business trips, such as the placement of headquarters and branches, which may not be adequately addressed by this model. So, what is the extent of this demand? In this study, we focus on the errors in the estimates of the gravity model concerning intercity flow based on mobile phone location data, attempting to clarify the characteristics of its spatiotemporal distribution.
