Study on effects of the interurban transportation in consideration of frequency on region's growth and national land structure

Abstract

The construction of the interurban transportation network in Japan, which made centralized national land structure, has caused many problems, for example depopulation and decline of local city. Now, we must construct interurban transportation network in order to promote region's growth and to make decentralized national land structure. So we must analyze quantitatively the effect of interurban transportation on regions and national land structure. And frequency is an important characteristic of interurban transportation and have rarely considered. Then we try to clarify the relation between potential of interurban transportation and the region's growth with Expected Value of Generalized Costs; the index to evaluate the transportation network in consideration of frequency.
