2. Honolulu
Congestion score: 26.0
Population density: 1,586.7 people per sq. mile (5th highest)
Average commute time: 27 minutes (27th highest)
Percentage driving to work: 79.5% (14th lowest)

Honolulu is one of the densest metro areas in the nation, with more than 1,586 people per square mile, as of 2010. Commuters were also considerably less likely to get to work by car, truck or van than most Americans, and were far more likely to walk or use public transit. Although just two Honolulu road segments, barely totaling 11 miles, were among the nation’s 100 most congested corridors in 2012, the area still ranked exceptionally poorly. After years of planning and delays, Honolulu broke ground on a massive public rail transit project in 2011. The project has long been controversial due to its environmental impact, cost and the possibility of disturbing the burial sites of Native Hawaiians’ ancestors.

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.
