NAICS 485111 – Mixed Mode Transit Systems encompasses the operation and maintenance of public transportation networks that integrate multiple modes of transit, such as buses, light rail, streetcars, commuter rail, and paratransit services, under a unified system framework. This sector supports the planning, procurement, and execution of interoperable transit infrastructure, including fare collection systems, real-time passenger information, vehicle maintenance facilities, and signal priority technologies. In the federal contracting landscape, this NAICS code is critical to urban mobility initiatives, infrastructure resilience programs, and environmental sustainability goals driven by federal transportation grants and state-local partnerships. While primarily administered through state and local governments, federal funding flows through agencies like the Federal Transit Administration to support capital improvements and operational enhancements. No contractor data is available to identify leading primes or small businesses in this sector, indicating a fragmented or locally concentrated contracting environment where regional operators and transit authorities may serve as primary service providers without significant federal prime contract activity. No agency data is available to identify primary federal buyers, suggesting that procurement is largely decentralized, with federal support channeled through grants rather than direct contracts for services or systems. The competitive landscape is characterized by low concentration, with opportunities concentrated in metropolitan planning organizations and state DOTs receiving federal transit funds. Contractors with expertise in integrated transit management systems, ADA-compliant paratransit logistics, and smart mobility platforms are well-positioned to engage through state-level RFPs and federally funded infrastructure programs. Emerging trends include demand for electrified fleets, contactless fare systems, and data-driven scheduling tools aligned with the National Transit Database reporting requirements.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 485111 work as a small business.
The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.
13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
