Abstract
Various crimes have been steadily increasing and many people feel uneasy about public safety. Especially, the number of snatch occurrence in Osaka prefecture has been the top in Japan for the last 32 years, and it is a serious problem. This study aims to research relationships between road spatial factors and the occurrence of snatches by quantifying the spatial factors of roads.
In Abeno ward, Sumiyoshi ward and Higashisumiyoshi ward, belonging residential area, relationships between the occurrence of snatches and road spatial factors was studied. From the study, the reason why the rate of the occurrence of snatches is relatively lower in the area where visible distances of roads are from 25m to 50m can be explained by the types of snatches. And in the case of using bicycles, the number of the way to escape is emphasized in the snatch occurred in the narrow road.
