Embedded Pavement Telemetry and Real-Time Road Friction Broadcasting

V2Road connects smart roadbed sensors, embedded piezoelectric strain gauges, and optical friction probes directly to vehicle anti-lock braking and electronic stability control systems over direct V2I sidelink.

Knowing Road Grip Before Tires Ever Touch the Surface

Vehicle ABS modules only detect loss of traction after tire slip has already begun. V2Road broadcasts exact surface friction coefficients (µ) ahead of time, allowing vehicles to pre-charge brake hydraulics.

Core Engineering Areas

Real-Time Surface Friction Coefficient Sharing — Transmitting road friction values directly to vehicle electronic stability control modules.
Embedded Pavement Strain and Structural Health Monitoring — Measuring pavement fatigue and gross vehicle weights at full highway speeds.
Black Ice and Hydroplaning Early Warning Mesh — Identifying invisible ice formation and dangerous water depths before vehicle spinouts occur.
