• Description:
  This project evaluated driver adaptation in the hours, days, and months after the introduction of SAE level 2 (L2) systems into the driving task. Three existing naturalistic driving study (NDS) databases were analyzed: the L2 Naturalistic Driving Study, the Virginia Connected Corridor Elite Naturalistic Driving Study, and the Older Driver Naturalistic Driving Study. To best assess driver adaptation, the analysis identified three phases of exposure time to L2 systems: Phase 1 (under 3 hours), Phase 2 (3 hours up to 8 hours), and Phase 3 (over 8 hours). The results suggested that driver adaptation was present for high-risk secondary tasks, as significant increases in engagement were observed over the three phases, but only when L2 systems were active. Additionally, drivers set their vehicle speed above the speed limit more frequently between Phases 1 and 2, with higher speeds set when L2 systems were active as opposed to when they were inactive.
