According to the Texas Transportation Institute's latest study on traffic congestion, two of every three cars experienced congestion in their morning or evening trip in 2007. As expected, traffic congestion is worse in very large urban areas, but congestion has grown in small areas, too. The share of travel in congested conditions has more than doubled from 1982 to 2007 for each of the urban areas shown.
