Fairfield County drivers probably won't be surprised to find out that Stamford made the list of America’s top 20 cities with the worst traffic congestion, according to a study released Tuesday.

Stamford is the 17th most gridlocked city in the U.S., ranking between Austin, Texas, and Tacoma, Washington, according to traffic data company INRIX. People who commute by car to Stamford spent on average 41 hours stuck in traffic last year, costing $1,588 per driver.

With 85 percent of work commutes taken by car, the U.S. ranked as the most congested developed country in the world, INRIX found. And for the sixth year in a row, Los Angeles is the most congested city in the world, topping world capitals like Moscow, London or Paris, according to the study. With limited access freeways and arterials, Los Angeles drivers spent 102 hours sitting in congestion last year during peak periods.

Bridgeport and Danbury were ranked 57th and 58th, respectively, with drivers spending more than 20 hours on average a year in congestion last year.

In an earlier study, INRIX found that Fairfield County's worst traffic congestion "hotspot" is I-95 south at Route 136 in Darien to Stratford Avenue in Bridgeport.

The Cross-Bronx Expressway (I-95) in New York is the worst traffic corridor in the country, the study shows. The average New York driver spends 118 hours per year sitting in congestion, an increase of 37 percent over last year. According to INRIX, traffic jams cost New York City about $34 billion last year.
