Waking Up to the Challenge of Fatigue Management in Transportation
Bibliographic record
Abstract
While a vehicle operator falling asleep at the controls is the most obvious symptom of fatigue in transportation operations, less extreme and apparent fatigue levels are reliably associated with performance impairments in, for example, attention, information processing, memory, and situation awareness. Compared to in other industries, fatigue in transportation is made more likely by challenges to the body's circadian rhythm caused by shiftwork and travel across time zones. While experiencing fatigue is a normal physiological and behavioral state, for drivers, pilots, mariners, and other vehicle operators, experiencing fatigue while operating a vehicle can have catastrophic consequences. Fatigue can also contribute to heightened, though less-direct, risk for those who support transport operations, such as shift schedulers, supervisors, and managers. This discussion panel will explore high risk and important human factors challenges to fatigue management facing transportation workers and their industries today, and some practical, and proven, ways to manage them.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
