Examination of How the Duration of Secondary Task Engagement Changes Over Time in Lower Levels (L0 to L2) of Driving Automation

Limited available evidence suggest that drivers may engage in secondary tasks both in L0 and L2 at approximately equal rates. However, anecdotal evidence suggests that the length of task engagement is longer with L2 systems activated. The goal of this study is to quantify both the number and length of secondary task engagement across levels of driving automation (i.e., L2 active vs. inactive) in a naturalistic setting. Baseline and L2 systems may vary (e.g., conventional cruise control and lane centering), atypical applications of Advanced Driver Assistance Systems (ADAS) are not necessarily excluded
