About UNSPSC 46161500
UNSPSC 46161500 Traffic control is a Class code covering the flagging operations, traffic management, signage deployment, and temporary protective devices that state and local governments deploy during roadway maintenance, construction, and inspection activities. State and local buyers under this code procure on-call and project-specific traffic control services—crew labor, equipment such as truck-mounted attenuators with arrow boards, portable changeable message signs, impact cushions, and associated setup and mobilization—as well as related signage and detection systems for intersection work. The code also captures maintenance and inspection support services where traffic control is a material scope component.
State departments of transportation dominate recent activity, particularly California's Caltrans and Pennsylvania's PennDOT, along with smaller cities and counties. California issued multiple Small Business Minor B traffic control and related solicitations (sign installation, signal detection replacement, curve warning signs, sidewalk work with traffic management); Pennsylvania's PennBID saw traffic control bids for bridge inspection support (STV Inc. on behalf of PennDOT, McArdle Bridge, October 20, 2026), sign structure inspection across six districts (WSP USA on behalf of PennDOT, due October 2, 2026), and logo sign installation (Pennsylvania Tourism Signing Trust, due October 15, 2026). The Utah Department of Transportation posted a five-year dual-award regional traffic control IFB (UDOT270063MP, regions 1–3, due October 16, 2026) specifying two-lane moving operations, impact attenuators, and portable message boards; the California Department of Water Resources posted on-call traffic control across six counties with mandatory 3.0% DVBE participation (due October 28, 2026). Massachusetts transit authority (MBTA) and municipal traffic signal maintenance bids also appear (Massachusetts Bay Transportation Authority Transit Signal Priority, Canton, Watertown, Cambridge, Marlborough). Geographically, recent activity clusters in California (Caltrans SB Minor B projects statewide), Pennsylvania (PennDOT and local road programs via PennBID), Utah, Massachusetts, Missouri (MoDOT), and Texas (Harris County). The code sees steady procurement volume across state DOT capital and maintenance programs, with small-business set-asides prominent in California and prevailing wage common across public works contexts.
