CHANGES IN DRIVING PATTERNS OF OLDER AUSTRALIANS: FINDINGS FROM THE CANDRIVE/OZCANDRIVE COHORT STUDY
Bibliographic record
Abstract
This paper describes changes in driving patterns for a cohort of older Australians. In-vehicle data-loggers installed in participants’ own vehicles monitored spatio-temporal characteristics of driving trips across three years for 164 participants aged 75+ years (Year 1: Male = 68.9%; Mean Age = 79.5 years, SD = 3.4 years, Range = 75 - 88 years). The majority (60–65%) of trips were within 5km from home across the three years. On average, in Year 1, participants drove 1,276 trips (SD = 479), totalling 9,468km (SD = 5,215) annually, decreasing significnatly to 1,175 trips (SD = 541) and 8,253km (SD = 4,813) annually in Year 3. Generalised Estimating Equations revealed that reduced driving (annual distance, trip frequency, night-time trips, peak-traffic trips) were associated with: increased age, being female, reduced cognitive function, poorer contrast sensitivity, and those that discontinued driving for health reasons. Results are considered in terms of implications for safe mobility.

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.
