U.S. Ranks Among Least Congested Countries Despite Urban Gridlock, TomTom Traffic Index Reveals

Event summary

  • Global congestion rose 5 percentage points to 25% in 2025, per TomTom's 15th annual Traffic Index.
  • U.S. ranked 54th globally with 19% congestion, despite Los Angeles topping domestic list at 60%.
  • New York City's congestion pricing reduced delays by 4 points on major roads, improved bridge performance.
  • Extreme weather caused up to 19% speed reductions in affected U.S. regions, with lasting infrastructure damage.
  • Hybrid work patterns reshaped commuting, spreading rush hour across wider timeframes and midweek peaks.

The big picture

TomTom's data underscores the tension between urban economic activity and traffic management, with congestion pricing showing early promise while climate change emerges as a growing disruptor. The U.S.'s relatively low national congestion masks severe urban hotspots, highlighting the need for localized solutions. As cities densify, the interplay between policy, infrastructure investment, and work patterns will determine mobility efficiency.

What we're watching

Policy Impact
Whether congestion pricing models like New York's can sustain long-term traffic reductions while managing local street redistribution.
Climate Adaptation
The pace at which cities integrate resilient corridor design to mitigate weather-related congestion spikes and infrastructure damage.
Workforce Mobility
How hybrid work patterns will continue reshaping urban traffic flows, particularly in tech-centric metros with midweek congestion surges.
