Abstract

t This study aims to evaluate the impact of spatial configurations within the street network—shaped by recent urban transformations—on indicators of urban vitality in Greater Cairo. It investigates the spatial relationships between the physical components of the network at both the local (neighborhood) and global (citywide) scales. Recent urban shifts have led to noticeable changes in street vitality patterns, resulting in significant disparities across different neighborhoods.

The research employs Space Syntax techniques to measure both local integration (Integration R800) and global integration (Integration Rn) of the street network as projected for the year 2025. It further analyzes the “foreground” structure—represented by major roads connecting city sectors—and the “background” structure—represented by internal local streets.

Findings reveal that the interplay between local and global integration levels plays a critical role in shaping urban vitality. Areas with high integration values on both scales tend to exhibit elevated levels of urban activity, reflected in dense pedestrian movement and a diverse mix of commercial and service functions. Conversely, areas with low integration values show diminished vitality.

Regression analysis also indicates a strong correlation between angular integration values—both local and global—and key indicators of urban vitality. These results underscore the importance for planners and decision-makers to prioritize the integration of foreground and background street structures in future planning for Greater Cairo, in order to enhance urban vitality and improve overall quality of life within the city.
