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.
Flagging does not guarantee removal.
