Depending on your commute, it may (or may not) surprise you to find out that Houstonians spend an average of 52 hours stuck in traffic per year, placing the Bayou City at No. 6 on the list of the United States cities with the most congested commutes.

The list, compiled using data from the Texas A&M Transportation Institute, looked at U.S. metropolitan areas with more than 500,000 residents and ranked cities based on how long commuters were stuck in traffic in 2012.

While Houstonians probably feel like this city has the worst traffic, that unfortunate honor belongs to Washington, D.C. where commuters average 67 hours stuck in traffic per year.

According to data complied by Nationwide Insurance, the average American living in an urban area spends 34 hours stuck in traffic each year, which is just about half of Houston's average.

Next time you're stuck in bumper to bumper traffic on 610 just remember that it could be worse. You could be in D.C. Of course, it also could be better.
