- Ten U.S. cities made the Top 25 worst congested cities in the world as employees return to the office.
- Nine out of 10 of the United States’ largest metros saw trips increase into the city core, capped by a sharp +25% increase in trips to Downtown Houston, followed by Chicago (+13%), Dallas (+12%) and Atlanta (+10%).
- Saturday and Sunday evenings saw the largest increase in trips, at 9% year-over-year, while Friday saw the biggest day of week growth when considering all-day trips.
- Congestion resulted in American drivers losing an average of 43 hours to traffic jams in 2024, equal to about one work week, costing $771 in lost time and productivity. Drivers in the most congested cities, New York and Chicago (102 hours), lost more than $1,800 in wasted time.
KIRKLAND, Wash., – January 6, 2025 – Today, INRIX, Inc., a global leader in transportation data and analytics, released the 2024 Global Traffic Scorecard that identified and ranked congestion and commuting trends in nearly 1,000 cities, across 37 countries. Istanbul’s 105 hours lost to congestion topped the worldwide rankings, followed closely by New York City (102 hours) and Chicago (102 hours). Ten U.S. cities made the Top 25 worst congested cities in the world as more employees returned to the office and leisure activity on nights and weekends increased as a result.
“Every year since 2020, we’ve seen traffic gradually rise towards what it was pre-pandemic,” said Bob Pishue, transportation analyst at INRIX and author of the 2024 Global Traffic Scorecard. “While the U.S. is still behind pre-2020 levels of traffic, a pullback of remote and hybrid work models, specifically in tech-heavy areas like San Jose, San Francisco, and Seattle, brought a large jump in downtown trips, which is a good sign for metropolitan economies. The data also shows more economic activity Saturday and Sunday evenings as the downtown core returns to life.”
The higher number of daily commuters heading downtown can bring economic benefits, but it’s a double-edged sword. Pishue continued, “Traffic can be an indicator of economic boon, but ironically, it’s a hamper on economies in of itself. Each minute spent waiting in traffic results in money and productivity lost.”
Americans Waste One Week a Year Sitting in Congestion
New York City, Chicago (both with 102 hours) and Los Angeles (88 hours) are the most congested cities in in the United States, costing drivers $1,826 and $1,575 respectively. The country’s biggest increase in traffic congestion came from 15th-ranked Denver, where residents saw a 19% increase in traffic delay compared to 2023.
Overall, congestion resulted in drivers losing an average of 43 hours to traffic jams in 2024, equal to about one work week, costing $771 in lost time and productivity. Nationwide, this sums to more than four billion hours lost, costing $74 billion in lost time.

Downtown’s Revival
Nine out of 10 of the United States’ largest metros saw trips increase into the city core, capped by a sharp +25% increase in trips to Downtown Houston, followed by Chicago (+13%), Dallas (+12%) and Atlanta (+10%). INRIX analysis has pinpointed that the increase in downtown trips across the country is not only due to a return to in-person work as Saturdays and Sundays saw the largest year-over-year increases in nighttime trips to downtown (12.5% and 12.7%, respectively). These findings suggest the same improvements cities made to attract employees downtown are also responsible for driving increased leisure/entertainment activity and a return to nightlife.
The Most Congested Corridors in the U.S.
Delay on the country’s busiest roads continues to be one of the most volatile traffic metrics. After holding three spots in the top 10 in 2023, Stamford, Connecticut’s infamous I-95 is now number one in the country’s most congested roads, seeing an influx of traffic from both commuters and freight truck drivers across the tri-state area. Roads in New York and California hold 12 of the 25 spots in INRIX’s most congested U.S. corridors rankings.

International Cities Grew at Faster Rate
While most large U.S. metros saw an increase in traffic delay in 2024, many areas outside of the United States grew at an even higher rate. Four cities in the Global Top 10 alone saw double-digit increases in traffic delay compared to 2023. For comparison, only five cities in this year’s U.S. Top 25 saw double-digit increases, with zero coming in the top 10. Additionally, 3 out of 4 cities in the 2024 Global Top 25 that saw year-over-year decreases in traffic congestion came from the U.S.

Notes to Editors:
Data Sources
INRIX aggregates anonymous data from diverse datasets – such as phones, cars, trucks and cities – that lead to robust and accurate insights. The data used in the 2024 Global Traffic Scorecard is the congested and uncongested status of every segment of road for every minute of the day, as used by millions of drivers around the world that rely on INRIX-based traffic services.
The Scorecard incorporates three years of historical data to provide a complete year-over-year comparison of congestion and mobility. A multi-year approach enables the identification of trends in the world’s largest urban areas and provides a basis for comparison.
Research Methodology
The 2024 Global Traffic Scorecard provides a comprehensive methodology to better understand movement in urban areas across the world. The 2024 Scorecard continues to include travel delay comparisons, collision trends and last-mile speeds based on the unique commuting patterns within each metro area, and the latest origin-and-destination patterns accommodate the latest commuting behavior shifts.
Commute times were calculated by looking exclusively at the time it takes to get to and from major employment centers within an urban area from surrounding commuting neighborhoods. Economic costs are calculated based on the following hourly values of time, which were based on U.S. Federal Highway Administration’s Revised Departmental Guidance on Valuation of Travel Time for Economic Analysis, 2016. Adjusted for inflation, the rates are the following: $17.90 per hour in the U.S., £9.33 per hour in the U.K. and 10.88 € per hour in Germany. Individual urban areas may have higher, or lower, values of time depending on local economic conditions.
The 2024 Scorecard values time lost by analyzing peak speed and free-flow speed data for the busiest commuting corridors and sub areas as identified by origin and destination patterns unique to that area. Total time lost is the difference in travel times experienced during the peak periods compared to free-flow conditions on a per driver basis. In other words, it is the difference between driving during commute hours versus driving at night with little traffic.
