  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?

  2. Does a fixed roadside sensor system that detects a specific vehicle-borne mechanical hazard and triggers a real-time driver alert intended t

    Roadside sensor system using edge-deployed AI to detect a vehicle-borne ignition hazard before pavement contact and alert downstream drivers in under one second. Target deployment: a western freight corridor with no parallel route and a documented history of multi-week closures from vehicle-generated ignition events.

  3. Autonomous vehicle-deployed aerial robotic inspection

    Would an autonomous vehicle-deployed aerial robotic inspection module be considered responsive if it performs multi-sensor catch-basin inspection without grate removal and produces AI-based condition assessments, or is the solution required to use a fixed vehicle-mounted boom?

  7. App requirements

    1. Is the app expected to be a mobile app, a web app, a voice assistant, or it is up to the proposer?
    2. Is there an expectation of the app working in offline mode?
    3. Should it include step-by-step navigation support?
    4. Can we assume that the users will have access to a smart phone? Should it work with non-smartphones and from web?
    5. Is there any requirements for multilingual support?

    Does edge computing refer to RSU-class roadside hardware, a local server co-located at or near a Transportation Management Center, or is the proposer expected to define and justify their own edge-cloud boundary as part of the system architecture?

  10. Does V2X include legacy vehicles alongside ELD-equipped fleets, or is V2X-native required?

    The solicitation references V2X integration for traffic management. Does "X" include non-connected legacy vehicles operating alongside modern ELD-equipped fleets? Our core innovation is dispatch optimization for mixed human/AV environments — understanding whether FHWA expects a fully V2X-native solution or a hybrid approach will determine our technical approach.

  13. The topic states the system “necessitates the creation of” new data standards beyond existing ones.

    The topic states the system “necessitates the creation of” new data standards beyond existing ones. For Phase I, does the DOT expect a new data standard to be developed and published, or is identifying the gaps where new standards are needed and proposing their design sufficient as a Phase I contribution?

    Would a mobile autonomous aerial sensing platform be considered an acceptable emerging data source if the proposed system’s main deliverable is an Edge-AI/V2X congestion advisory architecture that detects work-zone or incident-related congestion and delivers location-specific advisories to affected road users and traffic management operators?

    For the 80% baseline accuracy threshold stated in the Phase I objective: is this evaluated against a historical archived dataset, or must the system demonstrate 80% on a live real-time data feed during the Phase I period of performance?
