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 tracking the purchase of traffic detection and sensing devices that state and local governments deploy to monitor vehicle movement, signal timing, and roadway operations. However, the recent opportunities block shows minimal direct activity under this code — no solicitations explicitly named traffic flow sensors or inductive loop detection hardware as primary procurements. Instead, the block captures a broader range of traffic control, signal modernization, and roadway maintenance work where sensors and detection systems appear as subordinate components within larger capital or maintenance contracts.

The issuing bodies soliciting related work span state departments (California Caltrans, Texas TxDOT, Kansas Turnpike Authority), counties (Okaloosa County Florida, Cameron County Texas, Broward County Florida, Marion County Oregon and Florida, Denton County Texas, Sarasota County Florida), cities (Atlanta, Charlotte, Madison, Detroit, Brownsville, Dallas, Temple, Decatur, San Antonio, Fairburn), and special districts (Atlanta BeltLine). Representative recent opportunities include the City of Brownsville IFB 144-26-EPW for traffic signal communications and monitoring equipment (Field Monitoring Units, Roadside Units, managed network switches, and P5G gateways) with bids due May 28, 2026; Cameron County's Light Synchronization Project (IFB) seeking advanced traffic detection systems and GPS-based time synchronization at signalized intersections, due July 28, 2026; the City of Charlotte RFP 269.2026.209 for traffic signal loop installation and maintenance spanning 4,000 linear feet of lead-in cable and 25 inductive loop junction boxes, due May 21, 2026; and the California Department of Transportation District 08 IFB #08A3979 for inductive loop repair services (200 loop unit replacements, 50 detection station mainline loop repairs, 10 Type D bicycle loop repairs) across Riverside and San Bernardino Counties, due April 28, 2026. Geographic concentration appears strongest in Texas, Georgia, Florida, and California, with additional activity in the Midwest and Pacific Northwest. The code's recent opportunities suggest that traffic flow sensors and detection systems are procured primarily as components of signal upgrade, modernization, and maintenance contracts rather than as standalone commodity purchases, reflecting integration of detection technology into broader traffic management system deployments.
