Abstract

fetched live from OpenAlex

Free public transit for older adults is a policy often advocated for to increase ridership and reduce their dependence on automobiles. In July 2023 public transit became free on the island of Montréal for older adults (65+). Drawing from longitudinal repeated survey data collected in February 2023 and September 2023 and in-depth interviews collected in November 2023, we study the impacts of free public transit fare policy on older adults’ (65+) frequency of public transit use and satisfaction with service. We did not observe any change in public transit use among those who anticipated increased use in the before period, nor among those who anticipated no change in their use after the implementation of the free fare policy. We observed a positive change in the perception of the convenience of public transit after the implementation of the free fare policy for older adults.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
