NIGP 55091: Vehicle Detectors

NIGP 55091 Vehicle Detectors, an Item code, encompasses non-intrusive sensors—video, radar, and microwave-based systems—that state and local transportation agencies deploy for traffic signal control, vehicle counting, and intersection management. State highway departments and county transit authorities are the dominant buyers, with Texas Department of Transportation (TxDOT) alone issuing more than a dozen solicitations in the past four months across multiple districts. Texas repeats heavily in recent activity; Broward County Transit (Florida) is planning a CAD/AVL system procurement that will likely include detection components, and Marion County (Florida) is seeking TRAX Apollyon traffic counters compatible with existing TRAXPro software. Work is being solicited as firm-fixed-price IFB and RFO notices, almost always classified proprietary under state procurement code, with responses evaluated on lowest price and conformance to specifications. Wavetronix SmartSensor systems (16-beam stop-bar radar with 140-foot and 600-foot extended-range variants), Autoscope Vision (HD video with 720p resolution, 10X zoom, H.264 compression), Econolite Video Detection (similar video-based architecture), and Iteris Vector-Next platforms appear in multiple TxDOT districts; GS3 Processors (Cubic Transportation Systems computer vision units) and Currux Vision systems round out the active vendor base. Specifications consistently demand 95–99 percent detection accuracy, two-to-five-year warranties, NEMA TS2 compliance, FCC certification, and temperature tolerance from -29F to 165F. Management software integration with Windows 7/10 and export to CSV/JSON is standard. Installation timelines typically run 10–15 minutes per intersection; delivery defaults to 14 calendar days unless specified otherwise.

TxDOT dominates issuing volume across its Atlanta, Fort Worth, Houston, Beaumont, Bryan, Laredo, Waco, and Abilene districts; recent solicitations (July 2026) for Econolite Video Detection Systems (IFB 601310000102340, responses due July 24) and Wavetronix SmartSensors (IFB 601310000102310, responses due July 23) from the Fort Worth District exemplify the pattern. Florida activity includes Broward County's announcement of a July 30, 2026, CAD/AVL Industry Day (Government Center West, Plantation) with a fully competitive RFP forthcoming after a concluded RFI process, and Marion County's re-solicitation of TRAX Apollyon counters (May 2026) to assess alternatives to incumbent Jamar Technologies. California shows sporadic activity (Santa Clara County guardrail replacement with traffic-control-device components in April 2026). TxDOT solicitations uniformly require registration on the Texas Comptroller's Centralized Master Bidders List, Texas Family Code child-support certifications, acknowledgment of addenda, and firm pricing with F.O.B. destination freight prepaid. No set-asides for disadvantaged enterprises appear in recent notices; optional tie-breaker preferences favor Texas-produced goods, service-disabled veteran ownership, USA manufacturing, recycled materials, and energy efficiency under Texas Administrative Code Rule 34TAC 20.306. Vendors citing AI-based detection or analytics functionality must disclose algorithms, data handling, bias mitigation, and provide 45 days' advance notice of new implementations.
