UNSPSC 46161524: Traffic flow analyzer

A type of device that surveys the directions, kinds, volumes, changes in time and others of cars and people passing the cross section, artery road and others.

UNSPSC 46161524 Traffic flow analyzer, a Commodity code, encompasses the supply and installation of traffic detection systems, signal monitoring equipment, traffic signal control devices, and associated communications infrastructure that state and local governments procure to modernize traffic operations and improve signal coordination. Recent solicitations show state and local buyers purchasing advanced traffic detection systems with GPS-based synchronization, traffic signal cabinet assemblies, Field Monitoring Units and Roadside Units for communications networks, traffic signal LED replacements, and loop detection equipment—reflecting a shift toward integrated traffic management systems rather than standalone analyzer units. Cities, counties, and state transportation agencies dominate the issuing body mix, with the City of Charlotte, City of Brownsville, City of Madson, City of Detroit, City of Cameron County, City of Atlanta, and the Kentucky Transportation Cabinet among recent repeat solicitors. Geographic activity spans the Southeast (Florida, Georgia, North Carolina, Texas), the Midwest (Wisconsin, Michigan, Kentucky, Ohio), and the West (Utah), with Texas and Florida showing particular concentration in signal modernization initiatives.

Representative recent opportunities include the City of Brownsville's IFB for traffic signal communications and monitoring equipment (Field Monitoring Units, Roadside Units, Ethernet switches, and P5G gateways) with sealed bids due May 28, 2026, under TxDOT prequalification and federal funding; the City of Charlotte's RFP for Traffic Signal Loop Installation and Maintenance covering inductive loop sawcutting and lead-in cable installation with proposals due May 21, 2026; Cameron County's Light Synchronization Project soliciting advanced traffic detection systems and GPS-based time synchronization equipment at selected intersections, due July 28, 2026; and the City of Madison's RFB for 12-inch traffic signal LED replacements (WisDOT-certified) with proposals due May 22, 2026. Work is being procured on fixed-price and unit-price bases under ITBs, RFPs, and RFQs with response windows of 30–60 days. Federal funding appears in several recent opportunities, triggering Davis-Bacon prevailing wage compliance and Buy America requirements. The code shows sustained activity, with municipal traffic engineering departments and county transportation divisions consistently seeking equipment upgrades and modernization under cooperative purchasing vehicles and individual competitive procurements.
