Low-Latency Vehicle-to-Infrastructure (V2I) Telemetry
Vehicle2Infra synchronizes software-defined vehicle fleets with civil roadway infrastructure. Operating over dedicated 5.9 GHz roadside units, the system executes sub-millisecond optical and DSRC tolling reconciliation at speeds exceeding 200 km/h, enforces real-time variable speed limit envelopes to dissipate shockwave jams, and projects hazardous road work zones onto vehicle trajectory planners.

Eliminating Highway Congestion Chokepoints Through Continuous Digital Interfacing
Modern intelligent highway networks treat roadside infrastructure not as passive signposts, but as active real-time computational nodes. Vehicle2Infra integrates gantry-mounted LiDARs, high-speed cameras, and Dedicated Short-Range Communication (DSRC) transceivers to track lane occupancy, dynamically throttle approach speeds to avoid corridor shockwaves, and transmit sub-meter geographic bounding boxes of active work zones.
Core Engineering Areas
- Multi-Lane Free-Flow Tolling — Vehicle transponders and roadside gantry receivers exchange mutual authentication tokens, vehicle classification data, and encrypted payment vouchers in under 15 milliseconds.
- Variable Speed Limits (VSL) — Streaming mathematically optimal speed limits directly into vehicle cruise controllers to prevent shockwave stop-and-go congestion before it forms.
- Work-Zone Hazard Advisory — Smart cones equipped with low-power V2X beacons stream dynamic lane-closure polygons directly to incoming autonomous vehicles, forcing automated merge trajectories.
