This study is to suggest a new methodology of crime risk assessment and application method. The current crime risk assessment method is to infer the possibility of crime occurrence by analyzing the past crime data. But there are many limitations and problems to depend on the analysis with past data. Considering these problems, this study proposes the new methodology to assess crime risk integrated with the existing methods and various factors based on the CPTED principle. This methodology is named as 'Multi-Layered Risk Assessment (MLRA)' because it uses the various factors layered using GIS. The results of MLRA represent a visual graphic for easy interpretation after grading the crime risk. The characteristics of MLRA are able to grade the crime risk on the street and intersection and to be applied in CCTV positioning.
