Examination of Traumatic Brain Injured Drivers’ Behavioural Reactions to Simulated Complex Roadway Events
Bibliographic record
Abstract
This paper will discuss how traumatic brain injured (TBI) drivers exhibit a greater risk for traffic violations and motor vehicle crashes resulting from lasting behavioral and cognitive impairments. The purpose of this investigation is to examine the behavioral reactions of highly functional TBI drivers in response to simulated driving obstacles in comparison to matched controls. The present study sought to explore the deficits at the tactical and operational levels of Michon’s hierarchy of driver behavior which may contribute to the increased crash rate among highly functional TBIs as previously observed. Seventeen TBI and 16 control participants completed a simulated drive in which four separate surprising road obstacles were presented. Longitudinal acceleration, longitudinal velocity, lateral velocity and lane position were compared between groups. Results indicated that TBIs were slower to respond, swerved less, and were more cautious immediately after the obstacle had passed. TBI drivers also drove slower overall. Findings support deficits at the tactical and operational levels of Michon’s hierarchy of driver behavior. Differences at the strategic level are also discussed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
