Abstract

fetched live from OpenAlex

This paper provides a descriptive analysis of demographic aging and the changes in travel behaviour of the older population in the Greater Toronto and Hamilton Area (GTHA) in the Province of Ontario, Canada, from 1986-2006. The changing travel dynamics of the past and current groups of elderly population are examined in terms of out-of-home trip-making and primary mode of travel. These travel demand trends are analyzed in relation to age groupings that differentiate the baby boomers and the elderly as well as by trip purpose or activity. The paper reflects on these trends in regards to transport research and policy implications in an aging society.

Full frame distilled prediction

Teacher imitation

Not 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.
