This article attempts to explain the increase in commuting times in the 1990s after decades of stability. Although traditional explanations, for example both demographic variables (population growth and densities) and transportation variables (e.g. road capacity and transit use), pass the statistical significance tests, their overall impact was small. Instead, the article argues for the importance of strong income growth in the late 1990s, not least because it was associated with an increase in non-work vehicle miles traveled; these affect commuting times because many non-work trips take place in peak hours.
