Urban Structure and Commuting in Australian Cities

Abstract

Studies looking at the relationship between urban form and travel behaviour have generally considered spatial information at coarse metropolitan or local government area scales. We analyse ABS census data at the Collection District level for the metropolitan areas of the mainland Australian state capital cities, and at various spatial scales for an in-depth analysis of commuting in Sydney. The analyses suggest that the relationship between travel behaviour and urban form is complex, and that simple analyses of density alone are likely to overstate the effect of both metropolitan and neighbourhood scale population density on mode choice, but that these variables serve as useful proxies for more complex measures of urban structure.
