NASHVILLE, Tenn. (AP) -- A national traffic study shows congestion in Nashville has nearly doubled over the last three decades.
The 2012 Urban Mobility Report issued by the Texas A&M Transportation Institute says the congestion costs commuters money in lost time and extra fuel, as well as pollutes the region's air.
The institute estimates congestion in 2011 cost Nashville commuters $801 million.
Chip Knauf, the city's chief traffic engineer, told The Tennessean synchronized traffic lights on key corridors is one option in dealing with the congestion.
