Evaluation of Eyes Off Road During L2 Activation on Uncontrolled Access Roadways (VTTI-00-031)

Project Description: The current study investigated eyes off-road (EOR) behavior of drivers when traveling on uncontrolled access roadways in vehicles equipped with L2 automated features. Previously collected naturalistic driving data (NDD) were analyzed. 771 events were split between L2 features being active or available but inactive and matched across a spectrum of criteria (e.g., time of day). Primary analyses focused on L2 activation status (active or available but inactive and intersection type (no intersection, straight through intersection, and turning) and any interaction between those variables affecting EOR behavior for a given driver. EOR glances were operationalized in two ways: EOR 1) only forward was considered on-road EOR 2) all driving related glances were considered on-road. EOR metrics involved total EOR, mean EOR, single longest glance, and number of glances per event. Data Scope: 771 events are included in this dataset. 30-seconds of eyeglance data were reduced for each event. This dataset contains categorical and continuous variables that are based off of kinematic (i.e., speed) and video (e.g., eyeglance) data.
