112 범죄 신고 데이터 분석을 통한 캠퍼스 내에서의 범죄취약요소 연구

Abstract

This study is to examine the vulnerable environmental factors in university Crime Hot-Spot Area through campus field surveys and the correlation between safety system and statistical analysis. Seven campuses were used for current research wity using the data of 112 crime data with 1,793 crimes. We then analyzed Crime Hot-Spot Area through the Geographic Information System(GIS). For each university, vulnerable elements were derived in terms of the geographical characteristics of Crime Hot-Spot Area, the use of academic buildings, and the environmental design for crime prevention(CPTED). Crime Hot-Spot Area includes border areas(Edge effect) such as campus entrances, libraries, living halls, and student halls, as well as hospitals and parking lots on campus, nearby bus stops, and subway routes. Multiple regression analysis was conducted on seven independent variables related to vulnerable factors using the number of crime hot-spots as a dependent variable. The independent variables are the measured distance between the 112 report location and the CCTV, lighting, emergency bell, campus entrance, and general situation room. In addition, the correlation between the integration value of crime occurrence locations and the connection value through Space-Syntax analysis was also analyzed. The higher the number of Crime Hot-Spot Areas, the higher the integration value and the lower the connection value. Crimes have been concentrated on streets with high centrality and low connectivity on campus and streets with the characteristics of traveling in one direction. CCTV is a physical surveillance system known to be effective in crime prevention, but in this study, on the contrary, CCTV was installed closer as the number of occurrences in Crime Hot-Spot Areas increased. Lighting(CPTED surveillance index) was also related to crime occurrence in the analysis results of only one out of seven universities. Therefore, it was difficult to see lighting as an indicator related to campus crime prevention. It is important to analyze 112 police report data on important crimes such as theft, sexual violence, and violence that actually occurred on campus to derive accurate hotspot areas suitable for environmental characteristics. In the future, the results of this study that fit the characteristics of the university campus can be used.
