- Boston (149 hours lost due to congestion, which equates to more than six days) ranked as the most congested city in the U.S. for the second consecutive year, followed by Chicago (145 hours), Philadelphia (142 hours), New York City (140 hours) and Washington D.C. (124 hours)

- Bogota, Columbia topped the list of most congested cities in the world, with drivers losing 191 hours a year

- Los Angeles holds the two worst corridors in the U.S., where drivers on the US-101 and I-5 waste 80 and 76 hours per year at peak hours in congestion, respectively

- Philadelphia, Washington D.C. and San Francisco have the three slowest last mile speeds of 10 MPH in the U.S., meaning it is faster to bike than drive or taking the bus

- Congestion delays have decreased in four of the five most congested cities in the U.S., led by Washington D.C.'s 11 percent reduction

KIRKLAND, Wash., March 9, 2020 -- INRIX, Inc., a world leader in transportation analytics and connected car services, today published the 2019 Global Traffic Scorecard that identified and ranked congestion and mobility trends in more than 900 cities, across 43 countries. The report found that on average, Americans lost 99 hours a year due to congestion, costing them nearly $88 billion in 2019, an average of $1,377 per year. From 2017 to 2019 the average time lost by American drivers has increased by two hours as economic and urban growth continue nationally.

In the U.S., the 2019 Global Traffic Scorecard analyzed congestion and the severity of it in the top 66 urban areas. For the second consecutive year, Boston ranked as the most congested city in the U.S. with the average commuter in the metro area losing 149 hours per year to congestion, costing $2,205 per driver in time lost. Chicago (145 hours, $2,059 lost), Philadelphia (142 hours, $2,016 lost), New York City (140 hours, $1,988 lost) and Washington D.C. (124 hours, $1,761 lost) rounded out the Top 5. While known historically for its congestion, Los Angeles' (ranked sixth in congestion; 103 hours lost in 2019) constant gridlock does not have the severity as the other top-ranked cities due to its sprawling geography and massive road network. On the other hand, Wichita, Kansas, for the second year in a row, had the lowest congestion levels in the U.S. with drivers losing less than two hours a year.

"Congestion costs Americans billions of dollars each year. However, it appears to be stabilizing in some of the country's most congested metros – with delays raising roughly three percent nationwide since 2017," said Trevor Reed, transportation analyst at INRIX. "The continued innovation and investment in smarter roadway management is showing early signs of progress. To reflect an increasingly diverse mobility landscape, the 2019 Global Traffic Scorecard includes both public transport and biking metrics for the first time."

The Most Congested Corridors in the U.S.

Los Angeles holds the top two worst corridors in the U.S., where drivers on the US-101 and I-5 waste 80 and 76 hours per year at peak hours in congestion, respectively. In each case, the corridor uniquely serves a large geographic area with limited alternatives. In the case of US-101, it cuts through the Hollywood Hills, while I-5 runs diagonally into the downtown core across numerous other highways.
