Summary
This study addresses the limitations of previous driver distraction research, which primarily focused on operational tasks like lane keeping and failed to account for cognitive conflicts or tactical driving maneuvers. The research aims to understand how visual and cognitive distractions affect driver behavior and situation awareness (SA) across different levels of driving control, and to develop methods for classifying these distraction states. The motivation stems from the need to design effective assistive technologies that can detect distraction and mitigate safety threats posed by in-vehicle devices. The study employed a 2x2x2 factorial experimental design involving twenty young drivers who performed eight trials each in a driving simulator. The independent variables included driving control mode (operational vs. tactical), presence of visual distraction, and presence of cognitive distraction. Operational tasks involved lead-car following, while tactical tasks involved passing maneuvers. Data collection included overt performance measures, such as eye-tracking and vehicle control metrics, as well as internal process metrics, including situation awareness and perceived workload. Following the experiment, the researchers used a Support Vector Machine (SVM) algorithm to classify driver distraction states (visual, cognitive, and combined) based on the collected behavioral data. The results indicated that driver vulnerability to distraction depended significantly on the concurrent driving control mode. Visual distractions led to increased off-road glances and speed variances; however, drivers adapted to these distractions and maintained their situation awareness, particularly during operational following tasks. In contrast, cognitive distraction proved challenging during tactical driving, resulting in significantly degraded situation awareness and driving performance during passing tasks. Furthermore, the simultaneous occurrence of both visual and cognitive distractions limited adaptive behaviors, even under operational control modes. The SVM classification analysis demonstrated that distraction states could be inferred from changes in driver behavior, with the inclusion of real-time internal process measures adding value to the classification accuracy. The significance of this work lies in its extension of distraction state classification to include tactical driving tasks, thereby broadening the applicability of findings to real-world environments. By integrating real-time measures of both overt behavior and internal processes, the study reduces the gap between theoretical descriptions of driver internal processes and empirical assessment. The findings provide valuable insights for developing effective in-vehicle distraction mitigation systems and assistive technologies that can accurately detect and respond to various forms of driver distraction.
