Evaluation of the Criteria in the First Generation of CPTED Approach on Security of Public Space at Dehkade Farahzad of Tehran Based on ANP Model

ABSTRACT: While different elements including social, economic and cultural elements play a vital role in the emergence of behavioral patterns in humans, one cannot ignore the influence of the physical and spatial characteristics of built environment as a back ground for occurrence of anomic behavior on committing crimes. Therefore, a series of approaches and theories such as “crime prevention through environmental design (CPTED)” were developed. The first objective of this research is to determine the most insecure public spaces using parameters of the first generation of CPTED approach. The other objective is to evaluate the role of each one of these parameters in providing the aspect of security. In order to achieve these objectives, Tehran’s Dehkade Farahzad was chosen due to existence of the evidences indicating urban insecurities. This study is an applied type of research and the methodology used for achieving the goals was to benefit from ANP model which specifies the level of insecurity of urban spaces by evaluating the parameters of the first generation of CPTED approach. The methodology was performed using documentary and field research methods and statistical population used included 5 urban experts. The analytical results of model indicate that Tabbarok Street is the most significant urban insecure space in the mentioned site. In addition, the results demonstrate that territory and control parameters at a value level, activity support, image/management and maintenance, access control and intensifying the target of crime are respectively significant in determining the site’s security level.
