This study reports how to develop the roads network within spreaded residential area; Kamisaginomiya Nakano-ku Tokyo. From 1969, new development program started. In it, the collector roads would be developed by public and the front yard roads would be developed by private. Last report made it clear that the history of the development programs changing.
