NIGP 550: Markers, Plaques and Traffic Control Devices

NIGP 550 Markers, Plaques and Traffic Control Devices is a Class code under which state and local governments procure traffic signal equipment and installation, traffic control signs and devices, pavement markings, barricades, delineators, message boards, and related infrastructure to manage vehicular and pedestrian movement at intersections and work zones. Recent solicitations show active procurement across multiple equipment categories—from temporary portable message boards and traffic signal cabinets to permanent intersection installations and railroad crossing safety devices—along with associated professional services such as design, maintenance, and operations support.

Issuing bodies include county boards of commissioners, city public works and transportation departments, traffic engineering divisions, transit authorities, and specialized agencies such as airport authorities and toll road authorities. County governments and mid-to-large cities dominate the recent activity; repeat buyers include Hillsborough County Florida (traffic control rental, railroad crossing envelopes, and adaptive signal systems), Orange County Florida (supply and installation of traffic signal equipment, design services, and intersection replacements), Pasco County Florida (traffic signal installations), and the Cities of Houston, Charlotte, Gainesville, and Tucson. Geographic concentration appears heaviest in Florida, with secondary activity in Texas, New Hampshire, California, and across the Southeast and Southwest. Recent representative opportunities span Hillsborough County's three-year, $688,970 rental agreement for traffic control devices including variable message boards and arrow boards (ITB, October 28, 2026 response due); Orange County's $20 million five-year supply and installation of traffic signal equipment contract (July 21, 2026 response due); the City of Brownsville's 12th Street traffic signal modernization project funded through federal surface transportation grants (IFB, October 29, 2026 response due); and the City of Houston's paired safety improvement projects deploying speed cushions, crosswalk enhancements, and rectangular rapid flashing beacons across residential neighborhoods (RFP, October 8, 2026 response due). Federal funding (FDOT, FHWA, FTA) underpins many projects; Davis-Bacon prevailing wage, buy America, and FEMA compliance provisions are common. Design services, construction, equipment supply, and rental-with-maintenance models all see active solicitation.
