The Nature of Urban Growth and the Commuting Transition: Endless Sprawl or a Growth Wave?

Abstract

The concept of an urban growth wave expanding outwards is used to examine the commuting characteristics of residents of recently developed housing areas within the 50 largest US metropolitan areas at multiple points of time between 1980 and 2000. The results show that not only do areas of recent housing booms have longer commuting times and differing socioeconomic characteristics than older parts of the cities, but this commuting time will subside as these areas age (although average commuting times may rise for the entire metropolitan area). Like a growth wave, a commuting transition move outwards and therefore newer growth areas (or sprawl) should be considered as a temporary stage in the ongoing process of urban growth. Focusing on building cycles avoids the pejorative sprawl label and reconceptualises this sort of low density, auto-dependent urban form as a normal part of the urban growth process.
