Phoenix: A Traffic Dream Compared to Worst-Congested Cities

You think traffic is bad in Phoenix? Count your lucky cars. In a new study of the worst-congested cities in the world, Phoenix ranked No. 140. First place (which means the worst place)? Los Angeles.

The analysis of 2017 data, by the transportation analytics and connected car services firm INRIX, found that Phoenix drivers spend an average of 34 hours a year in traffic during peak hours — below the U.S. average.

The Top 5 (with average number of hours in gridlock):

  • Los Angeles (102)

  • Sao Paulo, Brazil (86)
  • San Francisco (79)

Other U.S. cities that are more congested than Phoenix: Atlanta, Miami, Washington, DC, Boston, Chicago, Seattle, Houston, and several others.

Overall, the U.S. ranked as the most congested developed country in the world, with drivers spending an average of 41 hours a year in traffic during peak hours, costing drivers more than $300 billion—an average of $1,445 per driver.

INRIX, of course, has some thoughts on this:

“Congestion costs the U.S. hundreds of billions of dollars, and threatens future economic growth and lowers our quality of life,” said Graham Cookson, the company’s chief economist. “If we’re to avoid traffic congestion becoming a further drain on our economy, we must invest in intelligent transportation systems to tackle our mobility challenges.”

The study was based on data from 300 million connected cars and devices, according to the firm.
