Increasing Socialization Based on Behavior Synomorphy and Physical Environment in Urban Spaces (A Case Study of Enghelab Square in Isfahan)

People's need for places for social interactions and to meet psychological needs is one of the necessities of urban life. By understanding the relationship between environment and behavioral patterns (synapomorphy), it is possible to help architects and urban designers to design suitable spaces. For this purpose, Enghelab square of Isfahan has been selected for the case study as a joint-maker area of two valuable and historical elements (Siosepol Bridge and Chahar Bagh Street) on the border of Zayandehroud. The research method in this research is based on quantitative and qualitative methods or a mixed one. Fieldwork, photography, observation, and questionnaire were accomplished to recognize the area, and the Delphi method and SPSS were used to evaluate synapomorphy criteria and indicators. The obtained results illustrated that four aspects (social interaction, images, environmental facilities, and space function) were the most significant factors in forming behavioral settings. According to the analysis, the indicators like activity variety and attractiveness activities, the easiness of accessibility to spaces, the possibility to sit and talk, the diversity of utilization, and arbitrariness with scores of 0.0909, 0.0866, 0.0823, 0.0799, and 0.0736 respectively have the most effect on synapomorphy of behavior and physical environment.
