The City of Culver City contracted with KOA Corporation to study, analyze, and develop recommendations for the installation of left turn signal phasing at seven existing traffic signals. The sites included the four intersections on the perimeter of Sepulveda Boulevard, Washington Boulevard, Centinela Avenue, and Washington Place, and three intersections along Jefferson Boulevard located at Duquesne Avenue, Jordan Way, and Machado Road. The project included recommendations on alternative methods of detection, evaluation of left turn and split phasing through microsimulation, preparation of signal timing charts, design of traffic signal modifications, and preparation of specifications and estimates. KOA also provided assistance during construction. The project was funded through the Federal Highway Safety Improvement Program (HSIP).
