The study revolved around the forests of Yangjae Citizen’s Forest, a park where the Crime Prevention Through Environmental Design (CPTED) was applied. The survey methods for analysis are as follows. From August to October, a total of eight surveys were conducted and 147 of the 300 samples collected were utilized for analysis. According to the results of the survey, 43.5% of participants were males and 56.5% were females. The highest number of participants visited the forest at midday and aged twenties visited most among all age groups. The participants visited the forest mostly with family and the main purpose of visit was for walking exercise including strolling. In case of criminal experience two sexual harassment (6.0%), and a fraud crime (3.0%) were tallied. Insecurity analysis resulted that “other users’ drinking” and “few Closed-Circuit Televisions (CCTVs)” were found to increase visitor’s insecurity. According to the psychological security analysis, participants reported they felt safer in open space than the enclosed areas. They also responded that dense wooded areas along the trails would increase the level of insecurity, while open space and resting areas were effectively relieve unsafe feelings. CCTVs and lighting fixtures facilities in the study area play an important role to effectively manage the park to prevent crime.
