Connecting Underground Metro Networks with Surface Autonomous Feeder Fleets

V2Subway standardizes the communication bridge between underground rail transit dispatch servers, subway portal leaky-feeder antennas, and surface autonomous feeder shuttles, eliminating passenger transfer waiting times.

Zero-Wait Commuter Transfer at Metropolitan Transit Hubs

Commuters lose up to 20 minutes waiting for surface buses after emerging from underground subway stations. V2Subway synchronizes surface shuttle departures dynamically with real-time subway train passenger loads.

Core Engineering Areas

Intermodal Connection Synchronization Protocols — Holding feeder bus departures dynamically when metro trains experience minor delays.
Underground Leaky-Feeder V2X RF Propagation — Maintaining communications across the difficult underground-to-surface transition zone.
First-and-Last-Mile Autonomous Shuttle Integration — Managing high-turnover passenger curbsides around major urban rail transit hubs.
