These 10 cities have the worst traffic jams in America

Sitting in traffic is the worst.

But in some US cities it's a daily routine for most commuters.

Goldman Sachs' Patrick Archambault shared a chart in a recent note to clients showing which large metropolitan cities in the US experience the most congestion. It's based on TomTom's traffic index, which measures the increase in driving times relative to the driving time if the roads were clear.

Somewhat unsurprisingly, Los Angeles is No. 1, with 39% longer travel times than if the roads were clear. Check to see the rest of the cities below.
