According to the U.S. Census Bureau, about nine out of 10 workers drive to work. An additional 5% of workers take public transportation, and about 2.5% walk. Of those that drive, about three out of four drive alone. The Census Bureau also estimated the average commute per worker (in 2005) at 24 minutes, which translates to about 100 hours of work-related commuting per year.
The Costs of Driving
Those 100 hours of driving to work (and "fighting" traffic) represent more than two weeks of vacation. Given worsening traffic conditions in major metropolitan areas, commute times appear to become exacerbated over the years.
