Abstract

This study set out to identify crime vulnerable areas with the GIS spatial analysis technique for the prediction of crimes. Crime vulnerable areas were extracted from the statistics of crimes with the GIS hotspot analysis technique and the inverse distance weighted(IDW) method applied to different crimes according to places and use districts. The scope of surveillance and weight were calculated for each of CPTED surveillance elements including CCTV, streetlamp, patrol division, and police substation. Maps of crime vulnerable areas were overlapped one after another to make a CPTED-based one expressed in four grades(safety, attention, warning, and risk).

범죄는 특정한 장소나 주변 환경에 따라서 범죄의 유형과 빈도가 매우 밀접한 관계를 갖으며 발생된다. 특히 공간적으로 범죄는 도심지역, 유흥가, 노상 등에서 많이 발생된다. 이러한 이유로 범죄와 발생장소와의 관계를 분석하는 것은 범죄를 예측하는데 효과적이며 이를 위해서 다양한 공간분석 기법이 적용되고 있다. 이에 본 논문에서는 범죄 예측에 활용코자 GIS 공간분석 기법을 이용하여 범죄취약지를 추출하였다. 범죄취약지는 범죄통계자료를 이용하여 장소와 용도지역별로 다르게 발생되는 범죄를 GIS의 핫스팟 분석(Hot Spot Analysis)과 역거리 가중법(IDW)을 이용하여 추출하였다. 또한 셉테드(CPTED)의 감시요소인 CCTV, 가로등, 지구대, 파출소에 대해서 각각 감시범위와 가중치를 산정하고 범죄취약지도와 중첩하여 4개 등급(안전, 주의, 경고, 위험)으로 표현된 셉테드 기반의 범죄취약지도를 제작하였다.
