2013 Urban Congestion Trends

This quarterly report is published by the Federal Highway Administration (FHWA) Office of Operations in Washington, D.C., to (1) provide timely congestion and travel reliability information to FHWA, U.S. Department of Transportation, and state and local agencies; (2) promote state and local performance monitoring to support transportation decisions; and (3) demonstrate the use of the National Performance Management Research Data Set (NPMRDS) for performance monitoring. In 2013, the average duration of congestion (speeds less than 90 percent of free-flow speed) was 4 hours and 30 minutes on interstates. The travel time index (TTI) on interstates in 2013 was 1.32, and the planning time index (PTI) on interstates was higher at 2.65.
