Quantitative Analysis of Street Network Features Using Space Syntax and GIS-Based Approaches: Ordu (Akyazı Neighborhood), Türkiye

Objective: This study aims to examine the relationship between visual accessibility and spatial components of different observation points in Akyazı Neighborhood of Ordu province by using space syntax, long line of sight and buffer analyses. Materials and Methods: Space syntax was conducted in Akyazı Neighborhood. According to this analysis, three different observation points (G1, G2 and G3) were determined at the intersection points of the high value paths of the sequential analysis. Long line of sight and buffer analyses were performed for these points. The data obtained were evaluated comparatively. Results: The results of the analysis show that G1 has the highest level of visual accessibility, whereas the viewing capacities of G2 and G3 are more limited due to spatial constraints. The main reasons for the differences in the level of visual accessibility are spatial factors such as spatial structure, connectivity values, building density, presence of open space, narrow streets, building heights and environmental barriers. Sequential analyses determined accessibility levels through connectivity and integration values, and when evaluated together with long line of sight analyses, the spatial relationships between accessibility, visual perception and pedestrian mobility became more evident. Buffer analysis revealed the relationship between walkability and accessibility levels and spatial organization through buffer zones created around the observation points. Conclusion: The results show that space syntax, long line of sight and buffer analyses are important evaluation tools in urban design and spatial planning. In order to increase visual accessibility, it is evaluated that elements such as building density, open space planning and street design should be handled in a holistic manner. In this context, the study suggests that the combination of space syntax, long line of sight analysis and buffer analysis can be an effective method to design urban accessibility, walkability and spatial perception more efficiently in Akyazı Neighborhood.
