Abstract:The following case study provides a snapshot of Long Island's INFORM transportation management center. It follows the outline provided in the companion document, Metropolitan Transportation Management Center Concepts of Operation - A Cross Cutting Study, which describes operations and management successful practices and lessons learned from eight transportation management centers in the United States and Canada. This case study reflects information gathered from interviews and observations at the INFORM transportation management center. The traffic management system was designed in the late 1970s and built in the early 1980s, containing variable message signs, ramp meters, traffic signals, and loop detectors, but no closed-circuit television. System operations went to 24 hours a day, 7 days a week in 1987. Communications occurred over coaxial cable. The control center was located in the State office building in Hauppage. The objectives of the system are to: identify traffic congestion and incidents or situations likely to cause congestion; and provide information to motorists and incident management resources to minimize the duration and impact of incidents.
