Public Transit & Infrastructure
Transit operations and service planning built by public transportation operators
Public Transit & Infrastructure is in expert discovery: M44 is documenting requirements and recruiting founding contributors to shape how transit AI gets built.
Industry landscape
The US public transit industry serves approximately 9.9 billion passenger trips annually across more than 3,000 transit agencies, representing over $75 billion in annual operating and capital expenditure. Transit systems range from large metropolitan authorities operating bus, heavy rail, and commuter rail networks to small rural providers running demand-response services, all governed by Federal Transit Administration (FTA) regulations and dependent on a mix of federal, state, and local funding.
Technology adoption in public transit lags behind private sector transportation, with many agencies relying on legacy Computer-Aided Dispatch and Automatic Vehicle Location (CAD/AVL) systems, aging fare collection infrastructure, and disconnected asset management databases. The transition to open-loop contactless fare payment, real-time passenger information systems, and predictive maintenance platforms is underway but hampered by procurement complexity and interoperability challenges.
Generic AI cannot understand transit service planning, federal compliance requirements, or the operational reality of multi-modal transit operations — which is why M44 is building applications for Public Transit. Domain experts who understand ridership forecasting, asset management, and FTA compliance shape the Transit application, not AI trained on scraped internet data. Transit planners and operations managers document the requirements from direct operational experience.

Who builds the Public Transit & Infrastructure application
Contribution process
Initial engagement
20–40 hours to establish foundational patterns, workflows, and knowledge structures for the industry module.
Ongoing contribution
2–5 hours per month to refine patterns, validate new capabilities, and contribute to module evolution.
Compensation model
Ownership
Blockchain-verified contribution records establish ownership stakes in industry modules, permanently and verifiably.
Revenue share
Ongoing royalties from module usage, proportional to contribution depth and module activity.
Professional standing
Contributors hold a verifiable record of expertise and direct client relationships through the platform.
General requirements
For the Transit application, early applicants define the requirements: service planning, fleet management, and federal compliance. Your knowledge of transit operations, FTA grant management, or multi-modal service delivery becomes the ground truth for AI that serves transit agencies. Apply as a founding contributor, and if there's a fit, we'll walk you through what to expect — including the business opportunity, contribution process, and how attribution works.
