Read research on the worst traffic hotspots in America, powered by INRIX Roadway Analytics

INRIX analyzed and ranked more than 100,000 traffic hotspots in the 25 most congested U.S. cities. The economic cost of hotspots was also calculated in terms of lost time, wasted fuel and carbon emissions over the next decade.

Insights from the US Traffic Hotspot Study include:

  • New York had more traffic hotspots than any other city, costing drivers $64 billion by 2026
  • Los Angeles, which tops the overall INRIX ranking, has 10 of the 25 worst traffic hotspots in America, costing L.A. drivers an estimated $91 billion over the next 10 years
  • I-95 in Washington D.C. was the worst overall traffic hotspot, which caused 1,384 traffic jams, stretched 6.4 miles and lasted 33 minutes on average
  • Research shows initiatives like the Illinois Tollway congestion relief project on I-90 is proving successful at increasing speeds

Bob Pishue, Senior Economist at INRIX, discusses the findings in the study further, which you can read in his blog.
