An Evaluation of Urban Structure in Tokyo Wards in terms of road capacity

Abstract

In Tokyo Metropolitan Area, the rapid increase of automobile traffic far surpasses the provision of road facilities. and the traffic congestion is worsening. One method to cope with this problem is the control of land use, especially the regulation of floor area ratio (FAR). In this study we examine if land use planning in Tokyo, which has the goal of the multi-nucleus urban structure. have corresponded with the road capacity. After the simulation study, although there are considerable gap between current FAR and permissible FAR, the planning urban structure is considered almost the same as a desirable structure alleviating the road congestion.
