Contributions and Limitations Walk Score <sup>®</sup> in the Context of Walkability: A Scoping Review
Bibliographic record
Abstract
Walkability is a critical component of built environments, yet there is still diverse conceptualization and measurement of the construct. The Walk Score ® metric is one measure of walkability, which is widely used in scholarly, industry, and public domains. With increased interest in the use of Walk Score ® as a research tool, it is necessary to examine the operationalization and scope of the measure. This scoping review examined how researchers utilized Walk Score ® in walkability research, with specific attention to identifying limitations related to health outcomes as well as the use of the metric in non-health research contexts. Findings from the review provide a novel and critically nuanced understanding of how the assumptions and limitations of Walk Score ® are addressed relative to socio-ecological aspects of walkability.

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.
