Traffic congestion nationally reached a new peak last year and is greater than ever before, according to a report by the Texas A&M Transportation Institute and INRIX Inc. Their analysis is based on federal data on the number of cars on the road and on traffic speed data collected by INRIX on 1.3 million miles of urban streets and highways.

Cities with fast-growing economies and the most job growth are the most plagued by traffic. Other factors: Urban populations are increasing and lower fuel prices are making driving less expensive, so more people are taking to city roads.
Congestion increased in 61 of the nation's 101 largest cities from 2012 to 2013, the data showed. The following year, nearly all cities - 95 out of 101 - experienced greater congestion.
The national average time that commuters wasted stuck in traffic last year was 42 hours, about the same as in 2007 and more than twice the delay in 1982, when the transportation institute first began assessing urban mobility. But because there are so many more commuters today and far more congestion in off-peak hours, total delay across the country has increased over 2007.
Overall, Americans experienced 6.9 billion hours of traffic delays in 2014 compared to 6.6 billion in 2007 and 1.8 billion in 1982.
