Recent studies have shown that--per person, per driver, and per household--we now have fewer light-duty vehicles, we drive each of them less, and we consume less fuel than in the past. These trends suggest that motorization in the U.S. might have reached a peak several years ago. The present study examined recent trends in the proportion of households without a light-duty vehicle as another index of the motorization level. Two analyses were performed. The first analysis examined the changes in this proportion for the entire U.S. from 2005 through 2012. The second analysis studied the variations in this proportion among the 30 largest U.S. cities for 2007 (the year with the lowest overall proportion) and 2012 (the latest available year). |
