The worst traffic in the Bridgeport, Conn., metropolitan area—which serves for many of the state’s commuters as a gateway to the New York metro area—was on a 22.2 mile stretch of Interstate 95 during the evening rush hour. Without traffic, it would take a driver 21 minutes to complete the stretch. During the week’s evening rush hour, it would take 44 minutes. The Bridgeport metro area had one of the highest population densities in the nation when measured by the 2010 Census.

The 10 U.S. cities with the worst traffic

Last year, the average American driver wasted 38 hours sitting in

traffic. While the occasional traffic jam inconveniences most drivers,

some unlucky people live in the nation’s most congested cities. To determine the 10 cities with the

worst traffic, 24/7 Wall St. reviewed figures published by INRIX, a

traffic information and services group. The INRIX scorecard assigns an

index score for the 100 largest metropolitan statistical areas, and

individual road segments within those areas. Scores are functions of the

percentage difference between road segments’ uncongested (or “free

flow”) travel time and the calculated travel time on the roads during

peak hours. 24/7 Wall St. also reviewed population density from the 2010

Census, as well as travel time and commuting methods for each metro

area from the Census Bureau’s 2011 American Community Survey. All data

used were the most recent available. These are the 10 cities with the

worst traffic.
