TRIMARC is part of a national initiative to deploy Intelligent Transportation Systems (ITS) to 75 of the nation's largest metropolitan areas. It includes an integrated system of sensors, cameras, dynamic message signs, highway advisory radio and computers monitoring more than 60 miles of interstate traffic in the greater Louisville and Southern Indiana urbanized area.

The Trimarc website offers this information and provides real-time streaming video of nine area interstate corridors and six downtown Louisville secondary streets. The site also offers traffic flow conditions and estimated travel times. In addition to dynamic messaging and web-based communication, information is available on government access television, thanks to a morning traffic program produced by Northrop Grumman and Louisville Metro Television.
