America's 50 Worst Commutes
Read to see how the data was established:
To find America's Highways from Hell, we started with newly released data from traffic-tracking firmINRIX, which culls data from 4 million vehicles nationwide using GPS units and a smartphone application.
We pared and ranked our top 50 worst metropolitan areas for traffic for 2010 using INRIX's Travel Time Tax—the percentage of time it takes to navigate the area's roadways during rush hour compared to uninterrupted travel periods. Los Angeles, no surprise, fared the worst, with a TTT of more than 35 percent. Then, using INRIX's analysis, we culled:
The worst corridor or bottleneck: A bottleneck is typically less than 3 miles long while a corridor is usually more than 3 miles. A corridor is a stretch of consecutive bottlenecks that experience significant congestion. While many larger metropolitan areas have corridors, smaller areas have only bottlenecks and experience relatively brief periods of congestion.
The rush-hour travel tax for the worst corridor or bottleneck: The Los Angeles section of the Riverside Freeway has one particularly bad stretch of about 20 miles. With a Travel Time Tax of 183 percent, it will take the average driver 183 percent more time to travel this stretch during rush hour than during uninterrupted travel periods. TTT is the price the driver pays for using the corridor during rush hour.
Average minutes per mile: At a rate of 65 miles per hour, driving a mile should take just under one minute. Not so on the Highways from Hell. A single mile on some of these roads can take more than four minutes to drive during the worst rush hours.
