Abstract
A certain period of time has been passed since started to discuss "Compact City". However the effects of Compact City have ever been researched in developed countries, the method, process, feasibility hasn't been clarified in Japan. Therefore it is important to seek how to realize Compact City. The purpose of this study is to propose concept of "Mobility Residue Value (MRV)" from a viewpoint of citizens. MRV is defined as the summation of utility about mobility, which one would receive during a lifetime. People have to recognize and consider MRV when choosing residence for realizing Compact City. Authors tried to establish the concept of MRV, and estimate by using traffic mode choice model. In consequence, it was verified that people in local city Utsunomiya would not decide residential choice in consideration of MRV.
