Overview
The "2021 Urban Congestion Trends" report from FHWA reveals an increase in urban congestion across the National Highway System. In 2021, daily congestion extended by 47 minutes compared to the previous year, with the average time spent in congested conditions rising from 2 hours and 18 minutes to 3 hours and 5 minutes. Similarly, the Travel Time Index (TTI) and Planning Time Index (PTI) both saw increases, with TTI rising by 6 points and PTI by 15 points. These measures indicate worsened traffic conditions in major metropolitan areas. The report also discusses the benefits of optimized traffic signal timing in Lincoln, Nebraska, which resulted in significant savings, including 1.2 million hours of delay and $23 million in cost savings.
