Investigating the Indicators of Sustainable Development in Urban Areas with an Emphasis on the Clarence Perry Neighborhood Unit Theory (Case study: Asadi neighborhood, 13th district of Tehran)

Many of the old neighborhoods of cities that once had a form of settlement-based solidarity are now booming due to a lack of revitalization of the body and activity. On the other hand, with the passage of time and the emergence of social changes in societies, many housing researchers are skeptical about repeating the traditional pattern of housing in new cities. What this study seeks to achieve is to examine the status of neighborhood sustainable development indicators with an emphasis on Clarence Perry Neighborhood Unit Theory through descriptive-analytical research method. The study area is Asadi neighborhood of Tehran 13th district, from which 384 residents are selected using the Cochran's formula. The questionnaire is distributed among them by cluster random sampling. The researcher-made questionnaire is validated by professors and experts and its reliability is confirmed by Cronbach's alpha of 0.781. Data analysis is performed through one-sample t-tests and Friedman ranking. The results show that the indicators of sustainable neighborhood development in Asadi neighborhood are in a poor condition (mean = 2.739). Among the indicators of sustainable neighborhood development, safety and security index (T = 4.975) have the best status and identity and vitality index (T = -27.229) have the worst status. Also, prioritization of neighborhood sustainable development indicators show that in this neighborhood, safety and security components are the first priority and environmental components are the last priority.
