Abstract

This study aims to assess the effectiveness and scope of influence of crime prevention facilities implemented within the context of the Crime Prevention Through Environmental Design (CPTED) project area. The analysis, which focused on 13 types of 351 facilities across seven research areas, studied crime patterns before and after the project. The research methodology encompassed various analyses, including crime rate changes in project areas and administrative dongs, alterations in crime types and hotspot distributions, facility density's correlation with crime, and crime analysis within a specific radius. This study innovatively employed a facility-centric buffer analysis coupled with hotspot analysis, distinct from prior research. The average reduction rate for the five primary crime types was -61.0% within one year. Crime decreased in three areas post-project, with a higher reduction rate compared to administrative dongs. The most effective areas in the CPTED project included theft or burglary, property crimes, and street crimes. Areas around crime prevention facilities exhibited diminished crime clusters and concentrations or hotspots. Statistically significant crime reductions were noted on streets with three to four installed facilities. Lastly, through a facility-oriented buffer analysis at intervals of 10 meters, this study identified the longest impact ranges of certain facilities. CCTV information signs and village etiquette signs displayed an impact range of 60 meters and 50 meters, respectively. External pipe intrusion prevention facilities and safety village information signs proved effective in deterring intrusion-related crimes. Meanwhile, logo-jecters, CCTV information signs, reflectors, and electric pole maintenance with location numbers demonstrated effectiveness in curbing street crimes. Additionally, door reflection sheets and electric pole maintenance with location numbers were found effective in reducing interpersonal crimes, and logo-jecters along with CCTV information signs were successful in addressing night-time crimes. In particular, door reflection sheets and wall maintenance including painting, which despite doubts about their efficacy, are extensively utilized in CPTED projects, and they have indeed demonstrated certain crime prevention effects.
