Public Transit Funding & Regulation

Federal public transit funding — authorized under 49 U.S.C. Chapter 53 and administered by the Federal Transit Administration (FTA) within the Department of Transportation — provides approximately $20 billion/year to approximately 1,300 public transit agencies across the country, supporting bus systems, subway and light rail, commuter rail, and rural and paratransit services that collectively carry approximately 7.5 billion trips/year (recovering toward pre-pandemic levels of ~9 billion). The Infrastructure Investment and Jobs Act (IIJA, 2021) authorized $91 billion over 5 years for public transit — the largest federal transit investment in history — funding a backlog of capital projects including New York's Second Avenue Subway, the Los Angeles Purple Line extension, and dozens of light rail and bus rapid transit projects in growing metros. Federal transit funding flows through formula programs: Section 5307 Urbanized Area Formula Grants (apportioned to large cities by population and ridership) and Section 5311 Rural Area Formula Grants (for smaller communities), plus competitive Section 5309 Capital Investment Grants (New Starts) for major new transit lines. The FTA requires a local match of typically 20% of project costs, ensuring federal funds leverage state and local investment. Transit agencies receive ADA paratransit requirements under Section 5310 funding, requiring complementary demand-responsive service within ¾ mile of fixed routes. The pandemic dramatically disrupted transit ridership and finances: federal emergency relief (CARES Act + ARP) provided ~$70 billion in one-time support; as those funds are exhausted, agencies face structural deficits — particularly in New York, San Francisco, and Chicago — that could force service cuts or fare increases.

Current Law (2026)

Legal Authority

• 49 U.S.C. § 5301 — Policies and purposes (federal interest in public transit to improve mobility, reduce congestion, conserve energy, improve air quality; transit important to the economic vitality of urban and rural areas; federal investment necessary because transit cannot be maintained/expanded without federal assistance)
• 49 U.S.C. § 5302 — Definitions (capital project, fixed guideway, local governmental authority, net project cost, public transportation, recipient, state, urbanized area)
• 49 U.S.C. § 5303 — Metropolitan transportation planning (metropolitan planning organizations — MPOs — develop long-range transportation plans and short-range improvement programs; public participation; coordination with state planning)
• 49 U.S.C. § 5307 — Urbanized Area Formula Grants (formula-based allocation to urbanized areas for capital, planning, and operating assistance for small urban areas; funding based on population, population density, and revenue miles of service; largest FTA program)
• 49 U.S.C. § 5309 — Fixed Guideway Capital Investment Grants ("New Starts" / "Small Starts" / "Core Capacity") (competitive discretionary grants for new rail, bus rapid transit, and other fixed guideway systems; rigorous project justification and local financial commitment required; the primary federal program for building new transit infrastructure)
• 49 U.S.C. § 5310 — Formula Grants for Enhanced Mobility of Seniors and Individuals with Disabilities (formula grants to states for capital and operating assistance serving elderly and disabled populations; non-profit and public agency recipients)
• 49 U.S.C. § 5311 — Formula Grants for Rural Areas (formula grants to states for capital, operating, and planning assistance in areas with populations under 50,000; critical for rural and tribal communities)
• 49 U.S.C. § 5323 — General provisions (Buy America requirements — rolling stock, steel, iron, and manufactured goods must be produced in the U.S.; Davis-Bacon prevailing wages; charter service restrictions; school bus protections)
• 49 U.S.C. § 5329 — Public Transportation Safety Program (FTA safety oversight of rail fixed guideway systems; state safety oversight agencies; national safety plan; safety performance criteria)

How It Works

Federal transit funding flows through several major programs to support public bus, rail, ferry, and paratransit services across the country.

The bulk of federal transit funding flows through formula programs — most money is not competitively awarded but allocated by statutory formula. The Urbanized Area Formula Program (§ 5307) is the largest, distributing funds to metropolitan areas based on population, density, and service levels; large urban areas (200,000+ population) receive funds directly while small urban areas (50,000–200,000) receive them through the state, for capital investment such as bus purchases, rail car procurement, and facility construction. The Rural Formula Program (§ 5311) serves communities under 50,000 population and is often the only public transportation available in rural areas. The Enhanced Mobility Program (§ 5310) specifically funds transportation for elderly and disabled populations. On top of formula funding, the Capital Investment Grants (CIG) program — known as "New Starts" — is the most high-profile competitive FTA program, funding major new transit infrastructure including subway extensions, light rail lines, bus rapid transit, and commuter rail. Projects must demonstrate "project justification" (mobility improvements, environmental benefits, economic development, cost-effectiveness) and "local financial commitment" (evidence the sponsor can fund their share and sustain the system long-term); the rigorous evaluation process takes years. Small Starts covers smaller projects ($400M or less), and Core Capacity funds expansion of existing fixed guideway systems at capacity.

Federal transit law includes some of the strongest Buy America domestic content requirements in federal spending — rolling stock (buses, rail cars) must be assembled in the U.S. with at least 70% domestic content, and steel, iron, and manufactured goods must be U.S.-produced. These requirements significantly affect procurement and have led all major bus and rail car manufacturers to maintain U.S. assembly operations. Following deadly rail accidents (Washington Metro, 2009; Hoboken, 2016), Congress strengthened FTA safety authority: FTA now regulates rail fixed guideway systems, requires State Safety Oversight (SSO) agencies to be independent of the transit agencies they oversee, mandates Safety Management Systems, and can issue safety directives and withhold funding for non-compliance. Federal law also requires metropolitan areas to establish Metropolitan Planning Organizations (MPOs) that develop 20-year long-range transportation plans and 4-year Transportation Improvement Programs (TIPs) prioritizing federally funded projects — transit projects must be included in the TIP to receive federal funds.

How It Affects You

If you ride buses, light rail, subway, or commuter rail: Federal transit funding — disbursed through the Federal Transit Administration (FTA) — is one of the reasons your system exists at all and why fares aren't higher. Approximately 20-25% of total transit operating and capital costs nationwide come from federal formula grants under 49 U.S.C. § 5307 (Urbanized Area Formula) and § 5337 (State of Good Repair), with the federal share being higher for capital projects (up to 80% in some cases). When federal transit funding is cut or frozen — as happened during COVID ridership declines and as DOGE-era reviews have targeted — the first effects are often service reductions, fare increases, deferred maintenance, and canceled capital projects. If your transit agency is facing a funding crisis, its FTA grant portfolio is public information: FTA's TEAM (Transit Electronic Award Management) system publishes active grants at transit.dot.gov. If your agency has proposed service cuts, the public comment process on the Transit Development Plan (or equivalent) is the point in the process where rider input matters most — after budget adoption, it's too late.

If you are elderly, have a disability, or depend on paratransit: Two federal mandates apply directly to you. The ADA (49 U.S.C. § 5301) requires all fixed-route public transit systems to be fully accessible — accessible vehicles, station lifts, and audio announcements are federally required, not optional amenities. Systems must also provide complementary paratransit that: covers the same geographic area as fixed routes within ¾ mile, operates during the same hours, and charges no more than double the regular fixed-route fare. If your transit agency's paratransit is denying trips, running late, or refusing to serve areas it's required to serve, file a complaint with the FTA Office of Civil Rights at transit.dot.gov/regulations-and-guidance/civil-rights-ada/civil-rights-complaints. The § 5310 Enhanced Mobility for Seniors and Individuals with Disabilities program funds specialized transportation beyond baseline paratransit — demand-response microtransit, volunteer driver programs, and other models for people whose needs aren't met by fixed-route systems. Find your state's 5310 coordinator through transit.dot.gov/funding/grants/enhanced-mobility-seniors-and-individuals-disabilities-section-5310.

If you live in a rural area where transit is the only transportation option: The § 5311 Rural Area Formula program is specifically for non-urbanized areas — rural counties, small towns, and tribal lands. It funds fixed-route rural buses, demand-response services (dial-a-ride), and intercity bus connections to larger hubs. Rural transit is often operated by non-profits, county governments, or regional planning organizations rather than large transit agencies. Service in rural areas is thinner than urban areas by design — the formula allocates funding partly by rural land area — but if your county has no transit and you need access to medical appointments, grocery stores, or employment, contact your state DOT's public transportation office about § 5311 funding and whether a new service could be established. The Community Transportation Association of America (CTAA) at ctaa.org advocates specifically for rural and specialized transit and maintains resources for starting new rural services. The IIJA (2021) increased § 5311 formula funding by approximately 70%, creating new capacity for rural transit expansion.

If your city or region is planning a new transit line or major capital expansion: The New Starts program (49 U.S.C. § 5309) is the primary federal source of capital funding for new fixed-guideway transit projects — new light rail lines, subway extensions, commuter rail, and BRT projects. The process from project initiation to Full Funding Grant Agreement (FFGA) typically takes 5-10 years and involves detailed FTA evaluation of cost-effectiveness (cost per hour of rider benefit), financial capacity, and project readiness. Federal share under New Starts is typically 40-60% of total project cost, not the full 80% theoretically available — FTA's evaluation process strongly influences how much federal funding a project receives. New Starts projects are scored on quantitative metrics that favor projects in dense corridors with high ridership potential; projects in lower-density corridors sometimes fare better under the Small Starts program (projects under $400 million). If your region is considering a transit ballot measure or a New Starts application, FTA's Project and Construction Management Guidelines at transit.dot.gov walk through the process; TransitCenter at transitcenter.org publishes independent analyses of New Starts evaluations and transit investment decisions.

State Variations

• State transit funding varies enormously — some states (New York, California, Washington) invest billions; others provide minimal state support
• State and local transit agencies have wide discretion in service planning, fares, and operations within federal guidelines
• Dedicated local transit funding (sales taxes, property taxes, payroll taxes) varies by jurisdiction and is often subject to voter approval
• State safety oversight agencies have varying levels of independence, resources, and authority
• Some states have created regional transit authorities (e.g., MTA in New York, BART/Muni in San Francisco, CTA/Metra/Pace in Chicago) with their own taxing and borrowing authority

Implementing Regulations

• 49 CFR Parts 601–670 — FTA regulations: capital investment grants, urbanized and rural area formula grants, state of good repair, transit asset management, Buy America requirements, and drug and alcohol testing.

• 49 CFR Part 611 — Major Capital Investment Projects (New Starts and Small Starts): FTA's implementing regulations for the Section 5309 Capital Investment Grant program — the competitive federal process for funding new fixed-guideway transit infrastructure. New Starts is how light rail lines, subway extensions, BRT corridors, and commuter rail projects receive federal funding:

  • § 611.201 — New Starts eligibility: a project qualifies as a New Starts project if it is a new fixed guideway (new rail, BRT on dedicated lanes, or streetcar) or an extension to an existing fixed guideway, requires a Full Funding Grant Agreement (FFGA), and has a total project cost of $300 million or more or requests federal New Starts funding of $100 million or more; projects below these thresholds qualify for the Small Starts program instead
  • § 611.203 — New Starts project justification criteria: FTA evaluates seven project justification measures: (1) mobility improvements — weekday transit trips served, including existing ridership benefiting from the project; (2) cost-effectiveness — cost per hour of transportation system user benefits (the most heavily weighted and most controversial criterion); (3) economic development — potential for transit-oriented development along the corridor; (4) congestion relief — vehicle miles traveled reduced; (5) land use — existing land use density and character, future land use plans; (6) environmental benefits — air quality, energy, greenhouse gas emissions avoided; (7) bicycle and pedestrian access — connectivity to non-motorized transportation; FTA assigns each measure a rating (Low through High) and combines them into an overall project justification rating
  • § 611.205 — Local financial commitment: FTA must find that the project has strong local financial commitment — the sponsor's plan to fund its share of project capital costs, operate and maintain the system over its life, and demonstrate overall financial capacity of the transit agency; a High/Medium-High financial commitment rating is generally needed to advance; financial commitment evaluation includes analysis of the transit agency's existing and projected revenues, capital plans, and operating budget
  • § 611.207 — Overall ratings: FTA assigns overall project ratings on a five-tier scale: High, Medium-High, Medium, Medium-Low, Low; only projects rated Medium or better are eligible to advance to engineering; the rating directly affects how much of the project cost FTA will agree to fund in the FFGA — High-rated projects typically receive closer to the 60% maximum federal share, Medium projects receive less; projects receiving Low ratings generally cannot advance without significant modification
  • § 611.211 — Before and After study: project sponsors must submit a plan to collect pre-opening baseline data (ridership, travel times, costs) and post-opening performance data 2 years after service begins; Before and After studies are FTA's accountability mechanism for the New Starts program — they allow FTA to compare actual performance against projections and inform future project evaluations; studies showing projects substantially underperforming projections can affect future funding from the agency
  • § 611.301 — Small Starts eligibility: Small Starts covers fixed guideway and corridor-based BRT projects with total project cost under $400 million or requesting less than $100 million in federal funding; Small Starts projects go through an expedited evaluation process compared to New Starts; corridor-based BRT (bus rapid transit operating in mixed traffic but with enhanced stations, off-board fare payment, and signal priority) qualifies for Small Starts even without dedicated guideways

  The New Starts process typically takes 5-10 years from first project development entry to FFGA execution: Alternative Analysis (comparing transit options) → Project Development (2+ years of environmental review and design, rated annually by FTA) → Engineering (detailed design, 1-3 years, requires FTA finding of medium or better rating) → Full Funding Grant Agreement (signed, committing federal share). FTA's annual Capital Investment Grant Report to Congress (required by statute) lists all projects under development and their ratings — this is the primary transparency document for the New Starts pipeline. Projects with federal commitments in FFGAs are not subject to annual appropriations risk (they have multi-year commitments), but new project entries require annual appropriations. As of 2026, approximately 50 New Starts and Small Starts projects are in the pipeline with combined federal commitments exceeding $25 billion.

• 49 CFR Part 661 — Buy America Requirements: the FTA implementing regulation for the statutory Buy America requirements in 49 U.S.C. § 5323(j), which prohibit FTA grant recipients from using federal funds to procure steel, iron, manufactured goods, or rolling stock unless they are produced in the United States:

  • § 661.5 — Steel and iron: all steel and iron used in a federally funded transit project must be manufactured in the U.S.; the requirement applies to steel and iron used structurally (track, infrastructure, building materials) — not incidental components; a small component or subcomponent with minimal steel/iron content may qualify for a de minimis waiver
  • § 661.7 — Manufactured goods: all manufactured products used in FTA-funded projects must be manufactured in the U.S.; a product is "manufactured" in the U.S. if it is processed or assembled in the U.S. and a significant portion of its components are U.S.-origin; this requirement covers everything from station equipment to communication systems to fare collection machines
  • § 661.11 — Rolling stock: buses and rail cars have a different, more nuanced standard — rolling stock must be assembled in the U.S. and have a minimum domestic content; the domestic content threshold is currently 70% (as increased by the Bipartisan Infrastructure Law of 2021 from 60%; the threshold increases to 75% in 2030 and 85% in 2032 under BIL's phased schedule); domestic content is calculated as the cost of U.S.-produced components divided by the total cost of all components; this is why major bus manufacturers like New Flyer (Canadian company) and BYD (Chinese company) operate or have operated U.S. assembly plants — it's a compliance requirement for selling buses to U.S. transit agencies
  • § 661.12 — Rolling stock certification: manufacturers must submit Buy America certifications with all bids for rolling stock; a false certification subjects the manufacturer to civil and criminal penalties; FTA audits compliance through post-award investigations
  • §§ 661.17–661.21 — Waivers: FTA may waive Buy America requirements if: (1) their application would be inconsistent with the public interest; (2) the materials or products are not produced in the U.S. in sufficient and reasonably available quantities of satisfactory quality; or (3) the inclusion of domestic material will increase the overall project costs by more than 25%; waivers are publicly noticed in the Federal Register and are relatively rare for standard transit procurements

  Buy America requirements are among the most practically significant procurement rules in transit — they directly shape the global transit vehicle manufacturing industry. When BYD (a Chinese EV company) attempted to sell electric buses to U.S. transit agencies, compliance with Part 661's domestic content requirements required either U.S. assembly or FTA waiver; the 2022 Consolidated Appropriations Act explicitly prohibited FTA grants from being used to procure rolling stock manufactured by entities with Chinese government connections, creating additional procurement complexity beyond Part 661 alone.

• 49 CFR Part 604 — Charter Service (50 sections — implements 49 U.S.C. § 5323(d), which prohibits recipients of FTA federal transit funds from using federally funded equipment or facilities to provide charter bus or van service if private charter operators are available to provide the service; the rule protects the private charter industry from subsidized public competition while preserving limited exceptions for transit agencies):

  • § 604.2 — Applicability: any entity that receives FTA funding under the Federal Transit Laws and operates passenger transportation is subject to Part 604; this includes fixed-route bus and rail systems, demand-responsive services, and vanpool programs; the prohibition attaches to equipment purchased with federal funds — agencies cannot use federally funded buses for charter trips even if they set up a separate charter division
  • § 604.3 — Prohibition: a recipient may not provide charter service using federally funded equipment or facilities if a registered private charter provider is willing and able to provide the service at a comparable price; the prohibition exists because Congress determined that public transit agencies with subsidized equipment would undercut private operators if allowed to freely compete in the charter market
  • § 604.4 — Exceptions to the prohibition: transit agencies may provide charter service only in narrow circumstances — (1) when no registered charter provider is willing or able to serve the request; (2) for qualified human service organizations (QHSOs) serving elderly, disabled, or low-income passengers when no registered provider is willing; (3) for government-sponsored public events such as city celebrations or special events at which the transit agency is the primary provider of transportation; (4) trips that do not exceed 80 miles from the recipient's geographic service area boundary; (5) emergency transportation when no alternative is available
  • § 604.10 — Agreement exceptions: if a recipient reaches a written agreement with all registered charter providers in its service area, it may provide charter service under the terms of that agreement; the agreement structure allows local solutions where transit agencies and private operators have negotiated coexistence
  • § 604.13 — Registration of private charter operators: private charter operators must register on FTA's charter registration website (updated annually) to claim protection under Part 604; an unregistered private operator cannot complain that a transit agency is competing with it
  • § 604.14 — Notification procedure: when a transit agency receives a charter request and wants to invoke the "willing and able" exception (claiming no registered provider is available), it must notify all registered charter providers in its service area of the opportunity, wait a prescribed period for responses, and document the outcome before providing the service itself
  • § 604.22–604.24 — Cease and desist orders: if FTA finds a recipient is providing charter service in violation of Part 604, FTA's Chief Counsel may issue a cease and desist order; the order is an aggravating factor in any subsequent penalty proceeding; repeated violations can result in suspension or termination of FTA funding — the ultimate enforcement tool

  The practical effect of Part 604 is significant for municipal transit agencies: a city bus system cannot rent out its buses for corporate events, sports team transportation, or school trips without first verifying that no private charter company is registered and willing to serve the same need. The registration system (the "charter registration website") is the practical mechanism — transit staff must check the registry and contact registered providers before providing most charter service. Transit agencies that fail to follow the notification requirements face FTA enforcement even when no actual private operator would have been able to serve the trip. The qualified human service organization (QHSO) exception is particularly important in rural areas where transit agencies are the primary mobility option for disabled and elderly riders who need transportation to medical appointments and social services programs.

• 49 CFR Part 673 — Public Transportation Agency Safety Plans: FTA's Safety Management System (SMS) rule requiring all transit agencies that receive federal funding to adopt and implement formal safety management practices. Enacted after a series of deadly rail accidents (Washington Metro 2009, 2015; Hoboken NJ 2016), Part 673 shifts transit safety from a compliance checklist to a systematic, data-driven safety culture:

  • § 673.11 — Agency Safety Plan requirements: each transit agency must establish a written Public Transportation Agency Safety Plan (PTASP) containing: a safety management policy signed by the CEO; safety performance targets aligned with FTA's National Public Transportation Safety Plan; a Safety Risk Management process; a Safety Assurance process; a Safety Promotion program; and documentation of accountabilities; small agencies (serving small urbanized areas) may adopt a State Safety Plan instead of developing their own
  • § 673.17–673.19 — Safety Committees: large urbanized area providers must establish a Safety Committee that is composed of equal numbers of management representatives and frontline worker representatives (including union representatives if the workforce is unionized); the Safety Committee must review the agency's safety plan, safety performance data, and proposed changes to safety practices; the requirement to include frontline workers — the people closest to actual hazards — reflects SMS best practices from aviation and other safety-critical industries
  • § 673.21 — Safety Management System (SMS): the four pillars of SMS under Part 673 are: (1) Safety Management Policy — CEO commitment, employee accountabilities, and safety reporting culture; (2) Safety Risk Management — systematic identification of hazards, assessment of risk (likelihood × severity), and mitigation; (3) Safety Assurance — ongoing monitoring of safety performance against targets, investigation of incidents and near-misses, and verification that safety controls are working; (4) Safety Promotion — training, communication, and culture building so all employees understand safety as a core value
  • § 673.25 — Safety Risk Management process: the agency must identify hazards associated with all elements of its public transportation system (vehicles, infrastructure, operations, maintenance, technology), analyze the probability and severity of potential consequences, and implement risk controls; risk controls must be tracked through implementation; residual risk after controls must be documented and accepted or escalated
  • § 673.27 — Safety Assurance: includes a monitoring process with safety performance indicators and targets (e.g., injuries per million passenger miles); investigation of all safety events (accidents, incidents, near-misses) to identify root causes; and an internal audit program to verify that SMS processes are being followed; for rail fixed guideway systems, the State Safety Oversight (SSO) agency reviews and accepts the PTASP and monitors agency safety performance

  Part 673 was phased in beginning in 2020, with full implementation required for all applicable agencies by mid-2021. The rule applies to any transit agency receiving FTA formula funding — over 3,000 agencies nationwide, from large urban rail systems to rural community transit providers. FTA may withhold or condition federal funding for agencies that fail to establish a compliant PTASP. Recent rulemakings: 88 FR 74060 (October 2023) — updated Part 673 to require Safety Committees with frontline worker representation and strengthen SMS requirements.
