Surprise: Traffic is bad in Los Angeles.



That's the upshot of the fifth annual Traffic Index report released Tuesday by GPS manufacturer TomTom, which found that Los Angeles is the most congested city in the United States, ahead of San Francisco, Honolulu, New York and Seattle.

According to the study, Los Angeles had an overall congestion level of 39 percent in 2014, up from the 2013 level of 36 percent. The average congestion level in the 10 worst cities in the country was 30 percent.

The situation is much worse during rush hour, when Los Angeles' congestion level jumps to 80 percent, also the highest in the nation.

According to the study, a drive that normally takes 30 minutes in Los Angeles, plus the extra minutes in the morning and evening rush hours, equal motorists wasting an extra 95 hours a year sitting in traffic.

San Jose had the second-worst rush hour congestion in the country, at 75 percent, followed by Seattle with 74 percent.

Among cities worldwide, Los Angeles ranked 10th worst. Istanbul ranked worst, followed by Mexico City, Rio de Janeiro and Moscow.
