CPTED Experimental Research Trends from the Research Methodology Perspective

Experimental research is a method suitable for intentionally creating the environment desired by the researcher and revealing the causal relationship between variables. The characteristics of these experimental studies are being utilized in the CPTED field to overcome the survey's limitations. However, there are few cases of experimental research conducted in domestic CPTED experimental research compared to other fields. And most of the simple experimental designs(pre-experimental design) are performed, so the design is insufficient. In addition, some studies have limitations that are difficult for subsequent researchers to apply because the experimental design and process do not appear in detail. Therefore, this study recognized the necessity of an effective experimental research system, and the concept of experimental research and the experimental design of previous studies were considered. Finally, the experimental design of the previous study was supplemented through the analysis results.
