Creation of New Multi-Level Urban Space for the Northern Osaka Station Area Development

In this paper, "Hyper-shaft" which is a unique urban infrastructure and some novel ideas of multi-level space are created, and traffic infrastructure planning is examined to meet the concept about the Osaka Station north district development. I have examined space devices of multi-layer / composition "shaft" and "loop" from the past. "Hypershaft" is an advanced urban infrastructure which is applied "shaft" and "loop" for a wider and more complex area. In addition, as the concrete elements of urban infrastructure planning, I suggest "three large spaces" and "Umeda Central Park" at the station outskirts. As for the traffic infrastructure, a formation consisting of both wide range and short distance traffic by bus and taxi is examined, and multi-level use of the station square is designed to make the formation possible. At the same time, basement usage of railroads and roads to make a certain room for passenger flows is also investigated in this article. Not on a viewpoint of the manager side but on a viewpoint of the user side, I tackled these problems to make attractive city space throughout this examination.
