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 includes the below items.
Design: Selection, evaluation and placement of field devices, including cameras, detectors, and DMS • Specifications on mounting details for all field devices • Performance of ongoing integration of system components
Operations: TEC staff provides operation assistance for the TRIMARC Control Center and also provides incident management support, operates DMS, and initiates emergency response through notification to local authorities, when needed.
Maintenance: Under contract with Northrop Grumman, TEC staff perform 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.
