Cross-Source Prediction of a Visual Load Index from Vehicle Kinematic Features: A Driver-Independent Validation Study
Highlights What are the main findings? Across held-out drivers, vehicle kinematics retained measurable information about the eye-movement-derived visual load index (VLI) proxy beyond the road-type baseline (ΔAUC = 0.042; 95% CI: 0.006–0.078). The driving-style prior increased AUC from 0.589 to 0.633, but its driver-lev...
