The influence of Driving Status on Transportation Challenges Experienced by Older Adults
Bibliographic record
Abstract
We explored the severity, number, and reasons for transportation challenges experienced by older adult drivers, nondrivers who live with a driver, and nondrivers who do not live with a driver. A random sample of 1,670 Atlantic Canadian community-dwelling older adults completed a mailed survey. Drivers comprised 80% of the participants. Just more than one fifth of participants experienced at least occasional transportation challenges. Two thirds of nondrivers who lived with a driver reported having no transportation challenges. Almost half of the nondrivers who did not live with a driver indicated never experiencing transportation challenges, and 84% of drivers had no transportation challenges. Nondrivers who did not live with a driver experienced greater frequency and severity of transportation challenges. This research contributes to our understanding of the characteristics of older adults with different driving statuses and their transportation challenges, which can contribute to providing appropriate transportation supports for older adults in the future.

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.
