UNSPSC 46161527: Traffic flow sensor

A type of device that measures the number of passing vehicles and their speed and others automatically with the electric signals after the vehicles stepping on and passing on as it is installed on major roads and intersections.

UNSPSC 46161527 Traffic flow sensor is a Commodity code that, despite its narrow title, captures state and local procurement of traffic control devices, barricades, pavement markings, and related deployment services far more than discrete sensor hardware. Recent state and local solicitations show that governments buying under this code are primarily acquiring barricade rental and deployment, temporary traffic control equipment (cones, drums, arrow boards, variable message boards, water barriers, jersey barriers), pavement marking materials and installation (thermoplastic striping, paint stripes, rumble strips, reflective tape), traffic signal poles and cabinet assemblies, pedestrian push buttons, and the labor to install, maintain, and remove these items. The mix of issuing bodies is broad: state departments of transportation (Georgia DOT, South Dakota Office of Procurement Management, Texas Department of Transportation), county boards of commissioners (Hillsborough County FL, Okaloosa County FL, Floyd County GA, Pasco County FL, Tattnall County GA, Sarasota County FL, Collin County TX, Cameron County TX), city transportation and public works departments (Atlanta, Charlotte, Dallas, Tucson, Denver, Brownsville, Madison, Temple, Detroit, Orange County, Hillsborough County), and transit authorities. Several jurisdictions post repeatedly: Atlanta (barricade deployment, street resurfacing with striping components), Charlotte (pavement markings, signal cabinets, loop installation), and Florida county governments (Hillsborough, Pasco, Okaloosa) appear multiple times in the October 2026 through May 2026 window.

Geographic activity is concentrated in the Southeast (Georgia, Florida, South Carolina) and Texas, with secondary presence in the Upper Midwest (South Dakota, Wisconsin, Kentucky) and Southwest (Arizona, Texas). The City of Atlanta Department of Transportation issued an IFB/ATLDOT/2609-1270082 for barricade deployment and traffic control for the Atlanta Streets Alive event series, bids due October 27, 2026; the Georgia Department of Transportation issued an RFQ for work zone temporary traffic control devices, quotes due October 23, 2026; and Floyd County Board of Commissioners solicited thermal and paint striping on 24 county roads totaling 57.8 linear miles under IFB 26-037, bids due October 22, 2026. Hillsborough County solicited rental of traffic control devices (signs, barricades, drums, cones, arrow boards, variable message boards, water barriers, jersey barriers) on an ongoing, as-needed basis under ITB2700002, bids due October 28, 2026, with an estimated three-year contract value of $688,970.00. Earlier in the cycle, the City of Tucson procured traffic signal and street lighting poles (67 line items, steel poles 7–65 feet, mast arms, strain poles, pedestrian push buttons, transformer bases) under IFB 270102 with federal ARPA funding and Davis-Bacon prevailing wage requirements, estimated annual usage $400,000; and the City of Brownsville solicited traffic signal communications and monitoring equipment (Field Monitoring Units, Roadside Units, network switches, 5G gateways, antennas) under IFB 144-26-EPW, bids due May 28, 2026, subject to federal FHWA Buy America and Davis-Bacon Act compliance. Set-asides and preferences vary by jurisdiction: some solicitations carry no stated restrictions (Georgia RFQ, Floyd County), others require MBE/WBE participation and goal waivers where federal or ARPA funding is present (Tucson, Brownsville), and Florida county procurements commonly require FDOT prequalification and Advanced Maintenance of Traffic certification. Activity shows steady demand across the portfolio with no seasonal cliff; the code remains active and worth monitoring for recurring equipment contracts and design/installation services tied to traffic signal modernization and pavement maintenance cycles.
