Impact of Reach Centralities on Urban Accessibility and Connectivity: Insights from Iraq

Abstract

Despite extensive research on spatial accessibility and connectivity, the specific role of reach centralities in differentiating areas with varying connectivity levels remains under-explored. In this context, this study examines the influence of reach centralities on the accessibility and connectivity of urban areas. It focuses on the Old Rusafa area in Baghdad, Iraq. Its aim is to determine if there is a correlation between reach centralities and the overall accessibility and connectivity of urban spaces.The study employs a case study analysis, spatial urban network analysis through software and geographic information system platforms.By incorporating reach centralities into the analysis and using a range of radii, extending from r:250 m to the entire area, the study produces a deeper understanding of the quality of the urban network, thereby highlighting the potential areas for development. The findings contribute significantly to datadriven decision-making in urban planning and design, advocating for the creation of urban environments that are not only more accessible but also intricately interconnected. This, in turn, promises to enhance the living standards of urban inhabitants.
