2015 Urban Congestion Trends: Communicating Improved Operations with Big Data

The Federal Highway Administration (FHWA) 2015 Urban Congestion Trends Report provides the current state of congestion and reliability in the largest urban areas in the United States. This report also highlights relevant successful operational strategies and performance management approaches implemented by State and local transportation agencies. Overall, congestion has slightly decreased from 2014 to 2015. Hours of congestion declined by 23 minutes from 5:03 (2014) to 4:40 (2015) and the planning time index declined slightly from 2.68 (2014) to 2.65 (2015). The travel time index increased one point from 1.33 (2014) to 1.34 (2015). This report marks the second year of calculating congestion and reliability metrics with the National Performance Management Research Data Set (NPMRDS). This report includes highlights of innovative ways States and local agencies throughout the United States have implemented effective operations and measured the impacts of congestion. The report concludes with a discussion of the importance of traffic volume data when aggregating performance measures.
