V2XTwins: Real-Time Digital Twins and Virtual Prototyping for Connected Fleets

V2XTwins powers large-scale simulation of millions of communicating automated vehicles, modeling microsecond RF propagation, urban canyon fading, and collective traffic flow.

Validating Autonomous Fleets in Cloud-Scale Digital Worlds Before Highway Deployment

Testing safety-critical edge cases like multi-car chain collisions or saturated 5.9 GHz channels is dangerous and costly on real roads. V2XTwins bridges physics engines with exact RF channel emulators.

Core Engineering Areas

• Co-Simulation Frameworks — Bridging micro-traffic simulators (SUMO) with wireless channel modeling (ns-3 / OMNeT++) in microsecond lockstep.
• Hardware-in-the-Loop (HIL) Emulation — Connecting physical V2X automotive ECUs to real-time FPGA channel emulators reproducing Rayleigh and Doppler shifts.
• Cloud-Scale Smart City Twins — Ingesting live cellular V2N telemetry into city twins to dynamically adapt signal timing and route emergency vehicles.
