Physical-spatial factors role in urban space security Case study: regions 6, 10 and 12 of Tehran

Introduction: In this regard, one of the priorities of urban planning is improving citizen security. According to fast urbanism development, one of the managers and urban planners' concerns is increasing citizen sense. Sometimes physical proceedings such as protection, guarding, control are planned in urban spaces to achieve and intensification urban security, whereas increasing citizens' security sense is more important in terms of using physical-spatial planning tools. The research target is to Survey the Impact of physical- physical-spatial planning tools. Methodology: spatial criteria in creating security sense for residents and studying the role of physical-spatial factors in increasing citizen security sense with applied approach and descriptive-analytical method. Case samples have been selected based on physical-spatial features cognition, including Administrative, decayed, and historical zone in three Regions of Tehran metropolitan. In the following, using ten influential physical-spatial factors obtained from experts and researchers' theories in the urban security field, by questionnaire with the validity and reliability of statistical items, level of citizens security in regions 6, 10, and 12 has been monitored and analyzed. In the research process have been used interpretive, survey, field methods, and Vikor method for comparative studies in mentioned areas Results: One of the essential physical features of District 6 is its location in the center of Tehran on the one hand and the establishment of the most essential administrative-service uses with trans-regional, urban, and even national functional scale in it on the other hand. District 10 is one of the urban areas of Tehran, which is located in the center of the city, and District 12 is considered one of the old districts of Tehran and has most of the old neighborhoods of Tehran. has taken. Indicate that in region 10, there is the highest security from citizens' view and environmental order role as the most critical criterion. The residents of region 12 feel the least security due to the abandoned spaces. Conclusion: Findings from the Shannon entropy method, according to the opinion of experts and specialists in the field of geography and urban planning, urban design, and urban planning, show the sense of belonging to space and attention to open and abandoned spaces with a weight of 0.1768 and 0.1740, respectively. They play spatial-physical and, according to the analysis of the questionnaires completed by the citizens using the Vikor method in District 10, District 6, District 12 of Tehran, respectively, has the highest to the lowest physical-spatial security. Paying attention to the sense of belonging and creating social connections and more presence of residents in public spaces is the most important in creating a sense of security and we should try to create spaces in urban areas with public participation to improve residents' interactions to promote a sense of security in urban areas
