Use of the light rail or light rapid transit systems by individuals with severe visual impairments
Bibliographic record
Abstract
This study investigated the relationship between use of Light Rapid or Light Rail (LRT) by persons with severe visual impairments and independence in orientation and mobility. Use of the LRT poses special problems to blind users and requires skill in mobility. The premise of the study was that blind persons who felt confident in travelling independently were more likely to use the LRT than those who do not. The study also examined the difficulties blind persons experienced in LRT use. The subjects were 63 persons between the ages of 19 and 65 who responded to a survey questionnaire. Thirty five of these individuals were male and 25 were female. All the subjects were registered as legally blind with the C.N.I.B. The range of visual loss included total blindness, light perception, tunnel vision, central vision loss and low vision. The results indicated that orientation and mobility training on the LRT system would resolve many of the difficulties that users of the systems encountered. Modification of the systems by transit companies to make the systems more easily accessible to visually impaired travellers are suggested.

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.
