Abstract: | This study questions the conventional wisdom about how commuting distances change when workers migrate from metropolitan to nonmetropolitan areas. It does not appear that decentralization yields a more energy-intensive configuration of residences and job locations: we find no indication that this migration lengthens the aggregate distance that workers commute. Some migrants do commute long distances, but their numbers are offset by many more who end up closer to their jobs. Our findings relate to two contrasting views (“sprawl” and “nucleation”) of how workers are becoming repositioned in relation to their jobs as settlement patterns change; the latter view appears more realistic. We briefly discuss policy implications pertaining to alternative transportation modes for commuting, setting priority travel needs in an energy emergency, and telecommunications as a substitute for commuting. |
