Population Distribution Change due to Interregional Transport Development

Abstract

The interregional transport developments, such as the Shinkansen and the expressway projects, may make a possibility of interchange better between both regions which are connected by such transport systems, and a higher growth for both regions can be expected. However, there are some cases that the agglomerate region enjoy the more benefit than the non-agglomerate one. This paper presents a population distribution model which can forecast the interregional transport developments effect, and estimate the population distribution change due to the future Shinkansen projects. As a result, we can find that the projects may have a possibility of population decentralization.
