UNSPSC 39121620: Transient protection materials

Transient protection modules, when combined with other measures, can help prevent problems caused by voltage transients. Transient energy may come from several sources, most typically environmental conditions or induced by switching heavy inductive loads. Sensors, readers, IT installations, etc., can be seriously affected if they are not protected.

UNSPSC 39121620 Transient protection materials (Commodity) covers traffic control equipment and temporary protective devices that state and local governments procure for roadway safety, construction site protection, and traffic management operations. Recent solicitations show this code capturing a diverse mix of temporary and semi-permanent traffic infrastructure—from traffic signal components and detection systems to physical barriers, striping, and protective devices deployed at intersections and along roadways.

State and local issuing bodies pursuing this code span transportation departments, city traffic engineering divisions, county commissioners' offices, and municipal public works departments across the country. Texas Department of Transportation (TxDOT) emerges as a repeat and high-volume buyer, posting multiple solicitations for traffic signal controllers, cabinet assemblies, backup power systems, and related infrastructure. Florida jurisdictions—including the cities of Orlando and Brownsville, Pasco County, Marion County, and Broward County—show consistent activity for traffic signal equipment, detection systems, and roadway modernization. Municipal buyers in Georgia (Atlanta, Fairburn, Thomas County), Kansas (Olathe), Colorado (Boulder County), California (Santa Clara County), and other states round out the geographic spread. Representative recent opportunities include the City of Orlando's red-light camera traffic infraction detector system (RFP, September 17, 2026 response deadline) spanning 80 intersections with five-year contract term and optional extensions; Okaloosa County, Florida's maintenance of traffic and pavement markings (ITB, August 5, 2026 deadline) covering 124 line items of temporary control devices and markings under FDOT specifications; and Broward County's pine island road adaptive traffic control and fiber optics systems (ITB, March 9, 2026 deadline) deploying ATCS infrastructure, video detection, and signal controllers across nine intersections with 180-day substantial completion requirement. Work is also actively solicited in Texas (multiple TxDOT districts), Florida (multiple counties and municipalities), Georgia, Colorado, Kansas, California, and New Jersey, with federal funding (Carbon Reduction Program, STBG-MM, FHWA) driving modernization projects alongside local transportation surtax initiatives.
