Sports are one of the most essential categories of developed and developing societies, among which football, as the most popular sport in the world, receives special attention from governments. Therefore, to increase the attendance of people in stadiums, it is necessary for the managers to identify the factors influencing the attendance of spectators, both psychological and internal factors, as well as external and environmental factors, and to design and implement a written and specific strategy and plan. Having a sense of security is one of the influential factors in creating satisfaction in the audience. Due to the high cost of building sports facilities and spaces, care should be taken about many factors and variables, especially the correct location of such spaces, to enable easier access, fairer distribution, and greater security. Therefore, this research aims to analyze the environmental factors that affect security in sports facilities with the approach of crime prevention through environmental design in stadiums. The instrument in this research is a questionnaire on security in sports facilities with the effectiveness of crime prevention through environmental design. Finally, the artificial neural network system method was used in MATLAB (A 2018) and SPSS (V24) software to analyze the data and answer the research questions. Environmental factors of access, light and illumination, readability, visibility and natural surveillance, repair and maintenance, dynamics, functional disorders, and guide signs respectively had a positive effect on security and crime prevention through environmental design in sports facilities. Therefore, sports directors and architects must pay attention to these indicators in the design of sports stadiums.
