Now headquartered in Woodridge, Illinois, with regional offices in Indiana, Missouri, Minnesota, and Iowa, TCC supports agencies and contractors across eleven states. The team’s vision is practical and consistent: pair industry-leading products with attentive local expertise, factory-trained technical support, and application knowledge that helps transportation teams keep intersections safer, better coordinated, and easier to maintain.
An ATC cabinet is a traffic signal controller cabinet built around Advanced Transportation Controller architecture. It houses the controller, monitor, power distribution, load switching, detection interfaces, communications equipment, and safety components that operate a signalized intersection. Proper cabinet selection, wiring, programming, testing, and preventive maintenance are critical because failures can lead to flashing signals, dark intersections, or unreliable detection.
