TRIMARC (Traffic Response and Incident Management Assisting the River Cities)
In 1997, Northrop Grumman was selected to design and operate an Advanced Traffic Management System (ATMS) and Traveler Information System for the Louisville, Kentucky/Southern Indiana region. The initial system was activated in 1999 and focused only on an 11-mile section of Interstate 65. The Traffic Response and Incident Management Assisting the River Cities – otherwise known as TRIMARC – has since expanded to cover more than 60 miles of regional interstates, with a strategic plan for expansion to more than 100 miles of interstate in Kentucky and Indiana. TEC’s role in the development of the TRIMARC system included the below items.
Design: Selection, evaluation and placement of field devices, including cameras, detectors, and DMS • Specifications on mounting details for all field devices • Developed communication systems and integrate into current FMS as new components were added.
Operations: TEC staff provided operation assistance for the TRIMARC Control Center. In this capacity, our staff provided incident management support, operated DMS, and initiated emergency response through notification to local authorities, when needed on a 24 hour per day, 7 day a week basis.
Maintenance: Under contract with Northrop Grumman, TEC staff performed maintenance on all TRIMARC field devices, including installation, diagnostics, preventive maintenance, repair/replace/restore actions, and end-to-end integration. The TRIMARC website, recognized by FHWA as one of the four best traveler- information websites in the country, provides real-time traffic information from the TRIMARC Control Center. TRIMARC has also been integrated with the statewide traffic operations center and 511 system using XML protocol consistent with the ITS National Architecture to convey incident information.
