Title: Multiscale Accessibility and Urban Performance

Abstract: Accessibility is fundamentally related to functional, economic and social performances of cities and geographical systems and, therefore, constitutes an essential aspect for spatial planning. Currently, studies have focused on cities or metropolitan scales, often disregarding their position within regional and national systems, which can greatly affect their performance. Although accessibility at various spatial scales has been examined, the studies focused on accessibility patterns at different scales, with no reference to the level of accessibility of cities over local, regional and national scales simultaneously, i.e., multiscale accessibility. This study aims to elucidate the multiscale accessibility level of individual cities and examine its relationship to urban performance in the urban system of Israel. Spatial accessibility was analyzed using the Space Syntax methodology for the entire national road network across multiple geographic scales – from the local to the national scale. Based on three distinct spatial accessibility systems identified, we created unique Multiscale Accessibility Profiles (MAP) for individual cities in Israel. Subsequently, each city’s MAP was examined against Urban Performance Indicators (UPI) determined from urban scaling theory. We found that the superiority of cities characterized by high accessibility level plays a role not only for a specific scale but also over scales and spatial systems. Moreover, most UPIs related to the MAP of cities while some MAPs can be related to over- or under-performance of cities. The findings suggest that pervasive accessibility across spatial scales is inherently connected to urban performance and may indicate on the implementation and interpretation of accessibility. These findings may assist in various aspects of spatial planning at various scales.

Speaker: Nir Kaplan is a PhD student at the Porter School of Environmental Studies and a researcher in the Urban Space Analysis Laboratory, Department of Geography and Human Environment, Tel Aviv University. In his dissertation he examines the influence of urban planning approaches on the relationship between movement volume distribution (especially pedestrians) in the city, land use pattern and street network structure. The areas of his academic interest include: pedestrian movement, urban morphology, agent based models, GIS and spatial analysis methods.
