NIGP 55081: Traffic Controls and Equipment, Electric Parts

NIGP 55081 Traffic Controls And Equipment, Electric Parts is an Item code that covers emergency and routine maintenance, repair, and upgrade of traffic signal systems and interconnected infrastructure, including signal heads, controllers, detection equipment, pedestrian signals, emergency vehicle preemption systems, backup power supplies, and associated electrical components. State and local governments soliciting under this code are purchasing on-call maintenance contracts, equipment and spare parts for existing signal networks, full traffic signal replacements and modernizations at individual intersections and corridor-wide deployments, and integrated traffic management systems combining detection, control, and communication capabilities. Recent opportunities span town governments, city public works and transportation departments, county engineering and transportation divisions, and state departments of transportation, with repeat activity from Texas DOT, which has posted multiple component-level procurements (controllers, cabinets, UPS systems, vision sensors) throughout 2026. The Town of Manchester, Connecticut issued an ITB for on-call signal maintenance across 97 town and state-owned locations due November 6, 2026, specifying familiarity with Alpha Technologies equipment and 24/7 emergency response capability under prevailing wage and DBE requirements. The City of Houston solicited proposals for a $75 million detention basin project encompassing one full traffic signal replacement and one modification among broader infrastructure work, due November 5, 2026. The City of Brownsville, Texas released multiple related solicitations: a construction IFB for traffic monitoring and management at signalized intersections (Cyber Lock devices, CCTV, Econolite Cobalt controllers) due May 28, 2026, and a separate IFB for the Carbon Reduction Program Light Synchronization Project deploying Wavetronix detection, NEMA TS2 cabinets, and GPS coordination at 33 intersections due May 21, 2026.

Geographic activity concentrates in Texas (TxDOT districts in Waco, Abilene, Amarillo, Lubbock, and San Angelo; Brownsville and Houston city procurement), Florida (Orange County, Collier County, Pasco County, Marion County, and Orlando city), Connecticut, and scattered municipal and county activity in Kansas, Georgia, North Carolina, and Wisconsin. Texas DOT accounts for the largest share of recent opportunities, primarily specifying proprietary Econolite equipment (ATC series, Cobalt controllers) and Alpha Technologies UPS systems under sole-source or proprietary procurements advertised under Texas Government Code 2155.067. Florida jurisdictions dominate adaptive traffic control and intersection modernization work, with Collier County, Orange County, and Pasco County each seeking design or equipment procurements. Prevailing wage, Davis-Bacon compliance, and federally funded set-asides (DBE, HUB, CBE) apply to many solicitations, particularly those using FHWA or FEMA funding. The code sees consistent activity across maintenance contracts, component purchases, design services, and full-system modernizations, indicating sustained government investment in traffic safety and congestion management infrastructure.
