Optimization Method for Population Distribution Using Land-Use and Transport Model of CUE Type

Abstract

Many cities in Japan are facing such various problems as economic recession, population decrease, shortage of financial resource, decline in city centre, and global and local environment problems. Compact city policies are required in order to lessen those problems. However we do not have a method to examine what urban structure is optimal and how the urban structure can be achieved. In this study, the method was developed by expanding CUE model (Computable Urban Economics Model), which was developed by Mutou and Ueda et. al., to an optimization model with objective function of social surplus, and then a modified Fowkes's method was applied for the optimization problem. Finally the developed method was applied in Nagoya metropolitan area, and the optimal population distribution to be achieved by income subsidy to households was found, which proved the applicability of the developed method.
