Today, INRIX published research on the worst traffic hotspots in America. Using INRIX Roadway Analytics, a cloud-based traffic analysis tool, 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 wasted time, lost fuel and carbon emissions over the next decade.
“Many cities are calling for increased transportation infrastructure spending to fix ailing roads, bridges and transit networks,” said Bob Pishue, Senior Economist, INRIX. “By identifying traffic hotspots and analyzing their root causes, cities can effectively combat congestion and maximize present and future investments.”
Ranking America’s Most Congested Cities
INRIX Roadway Analytics identified and ranked 108,000 traffic hotspots in the 25 most congested cities in the U.S identified by the INRIX Global Traffic Scorecard. The ranking was determined by an “Impact Factor,” which is based on the duration, length and frequency of traffic jams. The Impact Factor score enabled INRIX Research to estimate the economic costs at the road level and provided a metric to analyze the health of the transportation network within each city or metro area.
New York had more traffic hotspots (13,608) than any other city analyzed. However, Los Angeles topped the ranking with the highest overall Impact Factor, due to the severity as well as the high number of hotspots (10,385). This also means L.A. pays the highest price, with congestion at these locations potentially costing drivers $91 billion by 2026, if congestion doesn’t improve.
The impact of L.A. hotspots, and the potential cost to drivers, was 42 percent higher than the second ranked city, New York, and three times higher than Washington D.C. (ranked third). Atlanta and Dallas round out the top five, with Chicago, San Francisco, Houston, Miami and Boston making up the top 10. The economic cost to drivers due to wasted time, fuel and emissions in the 25 cities amounts to $481 billion by 2026. When extrapolated to a national level, traffic hotspots could total almost $2.2 trillion over the next decade.
