Work from home and online meetings have become spread due to a new lifestyle that prevents infection with the covid-19. With this spread, the workplace and the residence place do not necessarily have to be close to each other, which has an impact on our life. While it has become possible to choose a residence place that is not tied to the workplace. However, if it does not guide local city migration and country life to the right areas, It will become urban sprawl, and there is concern about the widening of the city. In this study, we analyzed changes in residence place and change in intention to choose a place of residence in the COVID-19. As a result, we pointed out that the way of thinking about choosing a residence place has changed, and that the actual situation of the residence place is also affected by the COVID-19.

Abstract:In this study, we created concentrated urban structure models based on the scenarios that demonstrate a compact city. We investigated urban districts, suburban sprawl areas and rural community areas. Moreover, we aimed to show a way to control land use and develop a future urban structure for local cities. The target area is the city of Yamaguchi, a non-area divided city 1) and the city of Hofu, an area divided city 1) . First, using 100 meter mesh data, we analysed urban structures by using district and population distribution. Then, we built future population distribution models from 2010 to 2060 for the target area. Moreover, we produced a "Knowledge Base of Planning Policy" in order to realize a compact city based on each master plan of the target area. Additionally, we set the "Rules of Population Migration" based on it. We created concentration urban structure models that applied the rules to future population distribution models. Lastly, we evaluated the concentrated urban structure models using the population distribution and the distance from urban facilities.
