A new report out of transportation analytics firm INRIX ranks Honolulu 10th on its list of the 10 most congested cities in the country, wasting 49 extra hours per commuter per year stuck in traffic.
The top 10 list also includes Los Angeles, Washington D.C., San Francisco, Houston, New York and Seattle, and commuters spent a total of 8 billion hours stuck in traffic in 2015 across all ten cities combined. INRIX also notes that the U.S. accounts for 50 percent of the top 10 metros with the worst traffic congestion across both the U.S. and Europe. Only London has worse traffic than top-ranked U.S. cities.
INRIX released its 2015 Traffic Scorecard today, a benchmark for governments and agencies in the U.S. and Europe to measure progress in improving urban mobility.
The report reveals that the U.S. faces large challenges to solve congestion issues, fueled by continued economic and population growth, higher employment rates and declining gas prices. Cities that have experienced the most economic improvement during the past year are at highest risk for consequences related to worsened traffic conditions, including reduced productivity, higher emissions and increased stress levels.
For example, Washington D.C., San Francisco, New York, Seattle and Boston all saw reduced unemployment rates bringing them below the national average of 5.3 percent for 2015.1 However, according to the INRIX Traffic Scorecard, congestion in those cities alone combined to waste 1.5 billion hours for daily car commuters last year.
Nationwide, commuters spent a total of more than eight billion extra hours stuck in traffic, representing almost 50 hours per driver.
City by city, here’s how the top 10 cities in the U.S. with the worst traffic rank in terms of average time wasted per commuter:
- Los Angeles, CA – 81 hours
- Washington, DC – 75 hours
- San Francisco, CA – 75 hours
- Houston, TX – 74 hours
- New York, NY – 73 hours
- Seattle, WA – 66 hours
- Boston, MA – 64 hours
- Chicago, IL – 60 hours
- Atlanta, GA – 59 hours
- Honolulu, HI – 49 hours
Although cities have invested in multimodal options, including public transportation, pedestrian programs and bicycle lanes, a strong economy often results in more drivers on the road. For most cities, applying big data to create intelligent transportation systems will be key to solving urban mobility. INRIX’s traffic analytics can help city planners and engineers with these efforts.
Fueling the transformation toward data-driven city planning is the U.S. DOT’s $50 million Smart City Challenge. Last week at South by Southwest® in Austin, seven finalist cities were awarded $100,000 to refine their proposals before the winner is chosen in June. As this effort by the federal government seeks to stimulate investment in smart cities, measurement and analytics will be critical to determine which solutions are most effective, optimize ROI for taxpayers and ultimately evaluate progress.
How the U.S. Compares to Cities Worldwide
At a city level, the U.S. accounts for 50 percent of the top 10 metros with the worst traffic congestion across the U.S. and Europe. London tops the list of gridlock-plagued cities, with 101 hours of delay per commuter, followed by Los Angeles (81 hours), Washington D.C. (75 hours), San Francisco (75 hours), Houston (74 hours), New York (73 hours), Stuttgart (73 hours), Antwerp (71 hours), Cologne (71 hours) and Brussels (70 hours).
Drivers on the top 10 worst roads globally waste on average 110 hours a year, or more than four and a half days, in gridlock. Of these corridors, four are in Los Angeles and three are in Moscow, followed by roads in London, Brussels and Munich.
Of the countries measured by the INRIX Traffic Scorecard, the U.S. leads the list of countries with the most hours wasted in traffic – an average of nearly 50 hours per commuter in 2015 – outranking Belgium (44 hours), Netherlands (39 hours), Germany (38 hours), Luxembourg (33 hours), Switzerland (30 hours), U.K. (30 hours) and France (28 hours).
Findings in the INRIX 2015 Traffic Scorecard are drawn from traffic speed data collected by INRIX on more than 1.3 million miles of urban streets and highways in the U.S., along with highway performance data from the Federal Highway Administration.
