The OCTA Magnolia Avenue Traffic Signal Synchronization project focused on enhancing traffic flow and reducing congestion along a 16-mile corridor spanning six cities—Fullerton, Anaheim, Stanton, Westminster, Fountain Valley, and Huntington Beach—through coordinated signal timing at 54 signalized intersections. Designed to improve mobility and environmental performance, the project delivered measurable results, including over $7.7 million in annual driver savings and $50,835 in greenhouse gas emission reductions. With a total cost of $205,800, the project achieved a remarkable 38:1 Benefit/Cost ratio. ADVANTEC led the development and implementation of signal timing plans, installed wireless radio communications at 11 locations, and upgraded signal cabinets and controllers at 3 intersections. By leveraging existing copper infrastructure with VDSL Ethernet-over-copper technology and coordinating across multiple jurisdictions, the project maximized cost-effectiveness and long-term operational efficiency.
