Traffic Signal & Control Systems in Council Bluffs, IA

Traffic signal installations require specialized electrical work coordinated with civil engineering, traffic engineering, and signal timing design. We install signal heads on mast arms or span wires, run conduit and wiring from controller cabinets to signal locations, wire traffic controllers according to specifications, install loop detectors in pavement for vehicle detection, and connect pedestrian signals with countdown timers and ADA-compliant audible signals. All wiring must withstand outdoor conditions and vehicle vibration while providing reliable signal operation for years.

Controller cabinets house the electrical systems that operate traffic signals. We wire controllers, conflict monitors that prevent conflicting green signals, flasher units for flashing operation during malfunctions, power supplies, and communication equipment for interconnected signals. Proper cabinet wiring ensures safe signal operation even when equipment fails—signals default to safe flashing red operation rather than creating dangerous conflicting greens. We follow MUTCD (Manual on Uniform Traffic Control Devices) requirements and manufacturer specifications for all controller cabinet work.

Ongoing maintenance keeps traffic signals operating reliably. We replace failed signal lamps (though LED signals rarely need lamp replacement), troubleshoot controller malfunctions, repair damaged wiring and conduit from accidents or construction damage, calibrate loop detectors, test conflict monitors and emergency vehicle preemption, and perform preventive maintenance on controllers and cabinets. When signals malfunction, fast response restores safe traffic control quickly. Our 24/7 emergency service ensures Council Bluffs traffic signals get the immediate attention malfunctions require.
