In order to achieve improved human well-being and sustainable urban management, there is a growing need for a planning process that shares the importance of the desired urban structure and the effects of different policies among different stakeholders. In this study, we constructed an urban structure simulation that combines sub-models estimating individual building replacement, personal relocation and residential choice, and zone-level land prices, using inputs such as 3D urban models. We analyzed the impact of policies such as the Location Optimization Plan and LRT on land use and population distribution in Utsunomiya City. As a result, we understand the effects of changes in the use of individual buildings and the increase in population due to policies such as the opening of the LRT, the improvement of bus convenience, and the guidance of residential choices and urban functions.
