| Abstract: |
In this article, we compute a variety of measures of urban form (or sprawl) for neighbourhoods of varying age in five study areas in the US to illustrate urban development patterns. Our analysis suggests that some characteristics of development patterns differ significantly within and across study areas and over time; this raises doubt about the utility of sprawl indexes for entire metropolitan areas. The findings suggest, for advocates of 'smart growth', that the good news is that single family lot sizes are falling, density is getting higher and neighbourhoods are becoming more internally accessible. For the same advocates, the bad news, however, is more extensive: houses are becoming larger, neighbourhoods are becoming more isolated, land uses remain separated and pedestrian accessibility to commercial uses is falling. If these trends continue, it is likely that housing will remain unaffordable, traffic congestion will only get worse and developments will be unsustainable. |
