Improvement of the City Fire Prevention Performance of Districts by Providing Small Open Space in Densley Built-up Area

Abstract

Small open spaces are provided to improve the problems of densely built-up districts by many local authorities. However, the city fire prevention performance of them has not quantitatively become clear. In this study, we attempted to make it clear in six densely built-up areas have different fire prevention performance by using the city fire simulation. In result, we got some new knowledge as follows; Burned area ratio is not decreased by few small open spaces in low fire prevention performance area, a strong wind decrease burned area ratio without depending on the city fire prevention performance, and so on.
