TRIMARC (Traffic Response and Incident Management Assisting the River City) is a project of the Kentucky Transportation Cabinet. TRIMARC was a part of the original 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 100 miles of interstate traffic in the Louisville Metro area and more than 50 mile of interstate traffic in the Northern Kentucky area south of Cincinnati. The TRIMARC project also provides and coordinates ITS asset maintenance throughout the state. Northrop Grumman is the system integrator and operator for TRIMARC. Northrop Grumman designed and manages the control center in Louisville that collects information on traffic flow, construction areas and accidents. Once collected, the information then is disseminated to motorists via dynamic message signs, highway advisory radio, local media and internet service providers.
