  1. The Complete Trip includes “plan for and pay for a trip”.

    The Complete Trip includes “plan for and pay for a trip.” Does Phase I require a functional payment integration (e.g., transit fare payment via API), or is a payment feasibility assessment and architecture design for Phase II implementation sufficient?

  4. What are the “unspoken” expectations of the agency for this topic?

    What are the “unspoken” expectations of the agency; for example, whether the solution should already exist or just be proposed? Also, what are agency expectations around adherence to previous work and studies listed in the References e.g "Mobility Data – Standards and Specifications for Interoperability (FTA/CUTR Project)"
    https://www.transit.dot.gov/sites/fta.dot.gov/files/2024-08/FTA-Report-No-267.pdf < is it strict or somewhat?

  5. Phase 1 Technical Requirement & MVP

    Does Phase 1 require a working payment integration, or is a feasibility/architecture plan enough? Is an end-to-end MVP expected at Phase 1, meaning from start of discovery, wayfinding, booking, payment of transit on the app?

  14. Complete Street Scoping

    For Topic 26-FT1, the solicitation states that the tool must empower travelers “across each segment of the Complete Trip,” including “trip planning and payment” and “enroute navigation support across the streetscapes, transit stations and vehicles.” For Phase I, should all listed Complete Trip segments and enroute environments receive equal focus in the proof-of-concept system design, or may the design give greater focus to barriers and/or environments that supporting research identifies as more burdensome to completing the trip?

  15. Transportation adjacent data sources

    For Topic 26-FT1, are the examples of “transportation-adjacent sources” listed in the solicitation illustrative rather than exhaustive, such that Phase I proposers may identify and assess additional relevant data sources that support Complete Trip decision-making and enroute navigation?

  16. Technical Scope: Operational Resilience and HCBS for 26-FT1

    For Topic 26-FT1, does the FTA consider AI-enabled solutions that predict and mitigate operational service interruptions—specifically in-cabin hygiene (bio-load) detection and predictive vehicle maintenance for specialized I/DD fleets—to be within the technical scope of 'Person-Centered, Carefree' planning?

    As these technologies directly automate the 'individualized back-up plans' required by the CMS HCBS Person-Centered Mandate (42 CFR 441.301) to ensure reliable community access, we wish to confirm if such 'operational resilience' innovations are viewed as a priority for achieving the 'Complete Trip' goal for underserved disability communities.
