Abstract
The purpose of this study is to obtain the finding for the safer school commuting road designing based on the Crime Prevention through Environmental Design. Therefore, we analyze relation between traffic or physical space elements and suspicious person infestations. Based on the assumption that the almost of the crime intended for children are occasional crime which occurs on school commuting roads in leaving school, and the hypothesis that physical space elements on traffic influence the occurrence of crime, we make suspicious person infestations model composed of existence densities of children. By this model, we was able to select points of discriminant analysis. As a analysis, we can calculate the impacts of the physical component elements on the suspicious person infestations.
