Safety as a basic human need has a considerable effect on citizens' life quality and urban spaces livability. Golestan neighborhood, as a minority group settlement located in central historical and old part of Sabzevar, have for several years been seeking ways to overcome their segregation. While according to studies securing a sense of safety is a main part of this endeavor, based on CPTED approach, due to its physical and functional deterioration, the mentioned neighborhood faces numerous challenges in terms of spatial-physical dimensions of unsafety. Therefore, through an analytical hierarchical process (AHP), this study aims to identify and prioritize the most important physical-spatial criteria and indices of the neighborhood causing its unsafety and undefendability,. This can provide a proper basis for any effective policy-making and decision-taking in the future planning for the area. Hence, after an in-depth literature review on CPTED theory, and deriving physical-spatial criteria and indices of urban spaces affecting their safety, a field study with 30 experts familiar with Golestan has been conducted. In the field study, the criteria and indices of the research AHP model have been weighed by expert panel via pairwise comparison matrix. The results of the present study showed that 6 main criteria and 19 sub-criteria were recognized affecting the safety of Golestan neighborhood. Furthermore, among the given criteria, physical permeability, liveliness, and legibility of Golestan neighborhood are the three most important environmental design features which negatively affect its safety. Also, Street geometry, paths width, and urban block system are the most important indices among the tested indices.
