In the days immediately following the January 17, 1994 Northridge earthquake in Southern California, a team of Caltrans traffic operations engineers was established to formulate possible traffic management strategies that could provide congestion relief during the reconstruction period. The proposals that were quickly developed became the earthquake relief Traffic Management Plan (TMP). Strategies included installation of motorist information and vehicle detection systems in the field and an Emergency Detour Management Center to control this equipment, a comprehensive public awareness campaign, short term traffic control measures, acquisition of communications equipment, helicopter surveillance, traffic data collection, tow service in the affected corridors, increased Highway Patrol support, and new park and ride lots. The rapid implementation of the TMP, and the successful part it played in dealing with what could have been a major transportation disaster was due in large part to unparalleled cooperation and assistance from the Federal Highway Administration. This report describes the various elements of the TMP and how they were implemented.
