NASHVILLE, Tenn. (AP) -- The Tennessee Department of Transportation is working on a free smartphone app using the traffic data it already collects.
According to WPLN, it's tentatively set to be available later this year.
The state already watches traffic congestion through a system of highway cameras, posting estimated drive times on interstate signs.
Gov. Bill Haslam says a smartphone program is meant to customize that information and put it in one place.
WPLN said the state has not publicized how much it will cost taxpayers.
