Abstract
BATON compiles 136.6 hours of naturalistic driving from 127 drivers across 380 routes, synchronizing front-view video, in-cabin video, decoded CAN signals, radar-based lead-vehicle interaction, and GPS route context to capture bidirectional control transitions between human and driving-automation systems. It defines three benchmark tasks: driving-action understanding (7-class), handover prediction (human→DAS), and takeover prediction (DAS→human), with baselines (GRU, TCN, XGBoost) and zero-shot vision-language-model evaluations. We find that visual input alone is insufficient for reliable transition prediction; adding vehicle dynamics and route context substantially improves accuracy; and that takeovers unfold gradually — benefiting from longer prediction windows — while handovers hinge on immediate context.
