ABSTRACT

A spatial separation of residential and commercial land uses is often highlighted to draw a typical image of sprawled urban expansion processes. And it is argued that the spatial structure where residential land uses are dominant in urban fringe may induce excessive automobile uses and consequently, derive many negative external effects. This study aims at examining sprawled urban expansion patterns over time characterized by land use separation. For this purpose, a quantitative measure(Separation Index: SI) is devised in a spatial statistical framework. The analysis results imply that SI can be used as an effective tool for diagnosing sprawled urban structure quantified as the degree of land use separation between residential and commercial land uses. In addition, local version of SI makes it possible to identify local regions where residential suburban expansion looks problematic. For those regions, it is worth to apply smart growth strategies promoting mixed land use. The analysis framework was demonstrated using empirical data for Erie County, Buffalo, NY in 1899-1995.
