UNSPSC 24101735: Air slide

This is an enclosed conveyor which is divided into two parts. On the top side material flows; on the bottom side compressed air flows in pulses. The two parts are separated by means of a porous fabric which the compressed air passes through and fluidizes the material being conveyed.

UNSPSC 24101735 Air slide is a Commodity code. State and local governments use this code to tag solicitations for traffic signal equipment, controls, and related intelligent transportation system infrastructure, though recent opportunities show the code captures far broader traffic signal modernization work than the narrow commodity name suggests. The category spans traffic signal cabinets, controllers, detection systems, communications equipment, pedestrian signals, mast arms, poles, LED heads, fiber optic infrastructure, roadside units for connected-vehicle systems, and field monitoring units deployed in citywide signal upgrades and corridor improvements. Issuing bodies include cities (Brownsville, Fort Worth, Dallas, Olathe, Round Rock, Richardson, Detroit, Broward County), counties (Harris, Pasco, Boulder, Bergen), and regional or statewide cooperative purchasing vehicles such as Purchasing Cooperative of America, which bundle traffic signal equipment and work zone safety services for multi-jurisdictional use. A small number of issuers appear multiple times—the City of Brownsville and City of Fort Worth each posted three to four related traffic signal modernization procurements in the recent window, signaling sustained investment in signal infrastructure through federal and local funding programs including the Carbon Reduction Program, Surface Transportation Block Grant–Metropolitan Mobility, and FEMA emergency restoration.

Recent activity concentrates in Texas, with Brownsville, Fort Worth, Dallas, Round Rock, Richardson, and Harris County all posting traffic signal and related infrastructure work between January and July 2026. Colorado (Boulder County), Florida (Pasco County, Broward County), Kansas (Olathe), Michigan (Detroit), New Jersey (Bergen County), and Georgia (Atlanta BeltLine informational session) round out the geographic spread. Representative recent procurements include the City of Brownsville's 12th Street Traffic Signal Improvement Project (IFB 145-26-EPW-IFB, due May 26, 2026) for removal and replacement of traffic signal systems, LED heads, pedestrian infrastructure, fiber optic communications, CCTV cameras with AI capability, and C-V2X roadside units across ten signalized intersections, and the City of Fort Worth's PW Meandering Road project (ITB, due March 26, 2026) encompassing traffic signal installation and other roadway improvements. Broward County's FEMA Emergency Traffic Signal Restoration and Repair ITB (due May 19, 2026) sought three-tiered vendor awards for emergency repairs and restoration on an indefinite-quantity basis with annual pass-through allowances of $345,000. Bergen County issued a 12-month traffic signal repair parts supply IFB (due February 27, 2026) under cooperative purchasing, and Boulder County solicited traffic signal cabinets via RFP with local-support-services and cost weighting.
