In order to systematically analyze the effectiveness of the CPTED project, this study analyzed the crime prevention effect of the project as well as the effect of crime transfer and profit diffusion through WDQ analysis. The main results of the study are as follows. First, as a result of analyzing the crime prevention effect of the CPTED project, it was found that Site 1 decreased significantly compared to the upper administrative dong, but Site 2 decreased smaller than the upper administrative dong. As a result of the hotspot analysis before and after the project, Site 1's hotspot was reduced more than Site 2, but in the two business areas, theft and street crimes decreased and violence increased in common. Next, as a result of the analysis of the effect of crime transfer and profit diffusion of the CPTED project, the overall effect of profit diffusion occurred in the buffer zone in the area-level analysis, but in Site 1, daytime crimes were transferred to the buffer zone, and in Site 2, intrusion crimes and nighttime crimes were transferred. In the analysis of the effect of crime transfer and profit diffusion at the horizontal level, Site 1 and Site 2 generally had profit diffusion on the buffer zone, but Site 1 had night crimes and Site 2 had theft transferred.
