VaN3Twin: the Multi-Technology V2X Digital Twin with Ray-Tracing in the Loop

Claudio Casetti, Diego Gasco, Eugenio Moro, Francesco Linsalata, Francesco Raviglione, Marco Rapelli, Roberto Pegurri

VaN3Twin is a new open-source digital twin that integrates ray tracing into V2X simulations to cut disagreement with real measurements by half in rural areas and over 70 percent in cities.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Compared to field measurements, VaN3Twin reduces application-layer disagreement by 50% in rural and over 70% in urban environments with respect to current state-of-the-art simulation tools.

C2weakest assumption

The assumption that integrating Sionna ray tracing with ms-van3t and the new interference module produces high-fidelity results without introducing modeling artifacts or requiring extensive per-scenario tuning, as stated in the framework description.

C3one line summary

VaN3Twin integrates ray-tracing into a full-stack V2X simulator to enable accurate multi-technology coexistence modeling and reports 50-70% better agreement with field measurements than prior tools.
