This research intends to improve the method of allocating crime prevention facilities in a residential district. Authors tried to calculate running speed of female youth as a means to measure distance to reach crime prevention facilities. In order to overcome conventional method of two dimensional buffer analysis, authors suggested new method of buffer analysis by considering gradient and refraction. Buffer areas for both conventional and new approach are compared after constructing GIS model of the site in Yeomri-dong, Mapo-gu, Seoul. The result shows that buffer area of crime prevention facilities drawn from conventional method (i.e. not considering gradient and refraction) covers 74.7%, whereas the area drawn from improved method (i.e. considering gradient and refraction) covers only 38.4% of the road within the site. The result indicates that conventional method of allocating crime prevention facilities does not guarantee safety of female youth in a steepy and bended alley. Therefore, when providing design guidelines for crime prevention facilities, it is necessary to apply the improved method considering gradient and refraction of the road.
