To successfully promote such a development pattern, an un- derstanding of development dynamics in station areas is crucial. In this paper, a node place model is used to determine which transport and land use factors are responsible for structuring station area redevelopments in Tokyo, and to what extent. e interaction between specic transport and land use features—most importantly, proximity by train to the central business district and the number of train connections versus workforce concentration—is a powerful force structuring developments in Tokyo. However, other factors—most notably government policies—should also be taken into account.

In this way, the operators of private railways hope to maintain In many metropolitan areas around the world, planners are at- their services as the natural choice of travelers pursuing their tempting to give railways a central role in urban development. daily activities.
