Imagining Age-Friendly “Communities Within Communities”: Uncovering Social and Physical Barriers to Age-Friendly Transportation
Bibliographic record
Abstract
Transportation policy and research extensively consider physical barriers to transportation, but often overlook social barriers to using transportation.Given that accessible transportation is associated with decreased prevalence of social exclusion and isolation among seniors who have been identified as most at risk (e.g., seniors with language barriers and mobility limitations), ethnographic field research was conducted in Ottawa to observe seniors' transportation use and explore potential links between transportation poverty and social disadvantages.Interviews and informal discussions were also conducted with seniors, seniors' service providers, bus operators, and transportation managers.The inclusion of multiple perspectives provided insight into seniors' transportation needs while considering how those needs are (or are not) translated into practice.Barriers to transportation involved the interaction between transport and social disadvantages.However, promising practices and/or facilitators of transportation appeared to involve initiatives that aimed to reduce transport poverty by addressing transportation inequities that resulted from social disadvantages.

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.
