Inrix recently released an update to the National Traffic Scorecard, a report that compares the status of traffic congestion throughout the top 100 metropolitan areas in the United States.  Inrix prepares this report each year by collecting and analyzing billions of datapoints from GPS-enabled vehicles traveling throughout the United States, including taxis, shuttles, trucks, and delivery vans.

According to the National Traffic Scorecard, Hampton Roads has higher congestion levels than many other comparable metropolitan areas.  Hampton Roads had a Peak Period Travel Time Tax of 13.0% in 2010, which means that on average a trip in Hampton Roads took 13% longer to complete during the peak travel periods than the same trip took during uncongested periods of the day in 2010.  The Peak Period Travel Time Tax increased from 11.7% in 2009, and among 35 metropolitan areas across the United States with populations between 1 and 3 million people, Hampton Roads had the 5th highest Peak Period Travel Time Tax in 2010.

Another measure collected by Inrix is the Worst Time Travel Time Tax, which looks at congestion during the busiest period of the week.  In Hampton Roads this busiest period occurs at 4:30 pm on Fridays, and produces a Worst Time Travel Time Tax of 42%.  This means the average trip took 42% longer to complete at 4:30 pm on Fridays than the same average trip took during uncongested periods of the day in 2010.  Compared to other metropolitan areas with populations between 1 and 3 million people, Hampton Roads had the 4th highest Worst Hour Travel Time Tax in 2010.
