Examining the correlation between residential environment evaluation and redesign measures to improve disaster prevention performance in densely built-up areas: A case study in the Shinyo neighborhood, Nagata Ward, Kobe

Abstract

There are many densely built-up areas in Japan that face danger from environmental disasters and need disaster prevention measures. However, streets in these areas provide a common space for activities such as socializing and increase the social comfort of living. Therefore, in addition to disaster prevention, such positive aspects should be retained when redesigning these areas. This study aimed to construct evaluation models of residential environments unique to densely built-up areas by using a questionnaire survey and to clarify the influence of redesign measures for improving disaster prevention performance on residential environment evaluation. The analysis results indicated that some disaster prevention measures have a trade-off relationship with many positive evaluation items of residential environments unique to densely built-up areas, although there is no trade-off relationship between disaster prevention measures and most evaluation items of a typical residential environment. Thus, it is necessary to develop redesign models that considers not only improving disaster prevention performance, but also an area's unique spatial characteristics.
