Urban public areas are the most important part of cities and urban environments in terms of the most contact, communication and interaction between people, and the concept of attendancy can determine this social interaction in dealing with the architectural body such as the bazzar. In Iranian urban architecture, the passage from one space to another space has been continuously repeated, without ever breaking the continuity. The concept of in-between in traditional bazzars is different depending on its design, and in the general sense it includes all entrances, courtyards, entrances, corridors, and in a more specific sense, in-between connections are known as the concept of in-between systems, which creates pausing and giving permission is at the user’s choice. The aim of the current research is to explain the index model of in-between spaces with the approach of attendancy in public realms such as historical bazzars. The research method is applied based on the purpose and descriptive-analytical based on its nature, and the method of data collection is from library sources, documents and internet sources, which according to the scope of the research, the field method was also used. In the first step and in the review of the background, the factors of attendancy and recognition of in-betweens and also the centrality of the bazzar are discussed. In the next step, according to the extraction of the factors affecting the subject, using the fuzzy Delphi method, a panel of elites and experts in the number of 15 people, using the Google Pot electronic questionnaire tool, was done digitally with the theme of the historical bazzar of Shiraz, and then the final indicators According to the rounds of the Delphi method, the evaluation model was extracted and explained. The findings indicate that 10 final indicators in the final compiled model were shared by the members, including the sociability index with an average score of 4.95, the spatial continuity index with an average score of 4.75, and the spatial determination index with an average score of 55. 4. and the user compatibility index with an average score of 4.56 are respectively the most and most effective factors in the formation of the research framework. The conclusion is based on the maximum impact of the perceptual and social component in the malleability of the concept of attendancy of intermediate spaces in public realms such as traditional bazzars.
