Cities are living organisms that if factors disturbing their ecological balance such as security are
not anticipated and controlled, they might deteriorated. One of the newest approaches to the
urban security crisis is to pay attention to the new generation of crime prevention through
environmental design. Given the success of CPTED worldwide, It is possible to achieve horizons in
promoting the concept of CPTED by presenting models and concepts. Also, there is a relationship
between the characteristics of the physical environment and the behavioral characteristics of the
occupants of residential spaces. Behavior of the deprived class achieved physical patterns of safe
living space. The present study is a combination of quantitative-qualitative methods in terms of
methodology of mixed research. First, the analysis uses a conceptual mapping process to discover
the theoretical position of each CPTED conceptual concept Categorized into conceptual topics,
then evaluated the components of CPTED according to the hypothesis, from documentary and
library methodology to the systematic review of relevant resources, followed by physical and
social typology of barricades by distributing questionnaires extracted from the data of the main
components of the research. The degree of importance of each criterion was assessed by SPSS.
Kolmogorov-Smrinov test and analysis of 384 questionnaires in 2020 and 2021 and presented new
concepts of CPTED. According to the outputs for the current model, the GOF is 0.63, which
indicates a strong fit of the model. All research hypotheses confirm and conclude the presentation
of the CPTED conceptual model with challenges in generations of this concept.
