Evaluation of Deteriorated Urban Fabric Pathways in Detailed Plans Based on Physical Indicators Using Space Syntax Technique (Case Study: Masjed Yeri Paein Neighborhood, Zanjan)

Introduction Following the failure of urban plans throughout the 20th century, a shift towards participatory urban planning, influenced by community-based planning theories, emerged in the late 20th century. Although this approach has been discussed for several decades, it has yet to be fully adopted in Iran. More than a decade after the approval and implementation of the detailed plan in Zanjan, many plots along the streets and facades remain undeveloped Research Objective : This study aims to evaluate the physical permeability based on the approved detailed plan and compare it with the findings derived from the Space Syntax technique and citizen perspectives, a decade after its implementation in the Masjed Yeri Paein neighborhood of Zanjan Research Methodology: This research is applied and employs a descriptive-analytical approach. It analyzes the street network structure of the Masjed Yeri Paein neighborhood using a combination of quantitative Space Syntax techniques and qualitative field observations. Geographical area of the research The study focuses on the street networks and accessibility patterns in the eastern semi-region of Zanjan, with an emphasis on the Masjed Yeri Paein neighborhood Findings and discussion: The analysis of the results and field observations shows that the roads in the area of the Lower Yari Mosque of Zanjan do not conform to the approved detailed plan in some key indicators (such as spatial integrity and connectivity) and this can be due to the inefficiency of the detailed plan in predicting the real needs Some streets have limitations in width, inconsistencies in pathway quality, and weaknesses in connectivity with main roads. Conclusion: New street expansions have been proposed to enhance physical permeability in both north-south and east-west directions
