Report and Data: Texas A&M Transportation Institute and Inrix Release 2015 Urban Mobility Study (Traffic and Commuting in U.S., UK, and Europe)

From the Texas A&M Transportation Institute

America’s traffic congestion recession is over. Just as the U.S. economy has regained nearly all of the 9 million jobs lost during the downturn, a new report produced by INRIX and the Texas A&M Transportation Institute (TTI) shows that traffic congestion has returned to pre-recession levels.
According to the 2015 Urban Mobility Scorecard, travel delays due to traffic congestion caused drivers to waste more than 3 billion gallons of fuel and kept travelers stuck in their cars for nearly 7 billion extra hours – 42 hours per rush-hour commuter. The total nationwide price tag: $160 billion, or $960 per commuter.
Washington, D.C. tops the list of gridlock-plagued cities, with 82 hours of delay per commuter, followed by Los Angeles (80 hours), San Francisco (78 hours), New York (74 hours), and San Jose (67 hours).

Scorecard findings also illustrate how traffic congestion isn’t just a big-city issue. Cities of all sizes are experiencing the challenges seen before the start of the recession – increased traffic congestion resulting from growing urban populations and lower fuel prices are outpacing the nation’s ability to build infrastructure.
Of America’s Top 10 Worst Traffic cities, 7 of them experienced population growth outpacing the national average of 0.7 percent last year, including Los Angeles, San Francisco, San Jose, Seattle, Houston and Riverside, CA. Additionally, some of the worst traffic cities also experienced some of the largest decreases in fuel prices (-4.1 percent nationally) including Riverside, Houston, Los Angeles, San Jose, Boston and Chicago. The result, the average travel delay per commuter nationwide is more than twice what it was in 1982. For cities of less than 500,000 people, the problem is four times worse than in 1982.

Findings in the Urban Mobility Scorecard are drawn from traffic speed data collected by INRIX on 1.3 million miles of urban streets and highways, along with highway performance data from the Federal Highway Administration. The vast amount of information, INRIX and TTI say, makes it possible to examine problems in greater detail than before, and to identify the effect of solutions at specific locations.
