Overview
By capturing the relationship between flexible road-based access and rail
transport, the dataset can support transport planning, demand
modelling, infrastructure optimisation, and AI-based mobility
analytics. Walking is also relevant as the most common mode
for short access and egress stages and therefore provides important context for interpreting where ride-hailing complements
pedestrian access to the rail network. Broader use of the data
is, however, constrained by the absence of scalable governance
and programmatic access mechanisms. This study examines the
feasibility of an architecture in which the underlying mobility
data remains off-chain, while a blockchain-based governance
layer manages access rights and provides auditable traceability.
The x402 protocol complements this layer by enabling authorised
software clients to pay for and retrieve defined data products
on a per-query basis without separate manual contracting for
each request. The study assesses the resulting requirements for
governance, privacy, automation, and institutional applicability
at the intersection of mobility-data markets, blockchain-based
access control, and machine-to-machine payments.
