Overview
In 2022, US urban traffic congestion trends showed a mixed picture. Average daily congested hours on freeways decreased by 10 minutes to 2 hours and 55 minutes. However, the Travel Time Index (TTI) increased slightly from 1.19 to 1.22, and the Planning Time Index (PTI) rose from 1.72 to 1.80, indicating increased travel time unreliability. While 73% of metropolitan areas saw no change or mixed results, 21% experienced worsening congestion, and 6% improved in all three measures. The report underscores the importance of data-driven approaches to address traffic challenges and emphasizes the role of the National Performance Management Research Data Set (NPMRDS).
