School travel planning: A Canadian pilot evaluation
Bibliographic record
Abstract
Background:Active school transport (AST) may be an important source of children's physical activity (PA). 'School Travel Plans' (STP) may increase AST by addressing school specific concerns such as road safety and traffic. Purpose:The purpose of this pilot study was to determine the potential impact of school travel planning (STP) for increasing AST in Canada.Methods: A pilot School Travel Planning (STP) intervention was conducted at twelve schools in four Canadian provinces. STP Facilitators worked with the schools to create and implement an action plan encouraging active transportation choices at each school. The intervention was evaluated using parental self-report (n=1520).Results: Thirteen per cent of families reported that they drove less to/from school because of the Travel Plan implementation. Thirty-seven percent of children walked to school and 43% from school to home. Distance and convenience were the primary reasons given for continued driving. Conclusions:While data provides tentative support for the STP process in Canada, it is critical that future STP initiatives explicitly address parental convenience and time constraints as barriers to greater AST.

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.
