The model shows that purse snatching was
reduced by increasing the intensity of illumination.

As the deterioration of public security is of increasing concern, a method referred to as CPTED (Crime Prevention Through Environmental Design) has gained particular interest in the field of city planning. CPTED is an effective way to address a prevalence of opportunistic crimes, which depend on the situation and scene, as most such crimes are committed in public streets. For this reason, the examination of street planning for crime prevention is important for urban security. In this study, we examine the relation between crime rates and street planning methods, including road designs and traffic regulations, focusing on street crimes such as purse snatching and prowling.
