LOS ANGELES (CBSLA.com) — Sitting in Southland traffic could be costing drivers approximately $1,300 year, according to a new study published by the Texas A&M University Transportation Institute.

The annual study calculates the cost of wasted time and fuel for major cities across the United States and found Los Angeles to be among the country’s most congested cities.

“We’re finding, of course, and you know it there in Southern California, that there’s delay at all times of the day. It’s not necessarily just something on the way to work,” researcher Bill Eisele told KNX 1070.

The study found that the average American wasted about $818 sitting in traffic in 2011.

Washington, D.C., was found to have the worst commute in America.
