Abstract
The Pedestrian Safety Evaluation Program was launched in April 2010 as a three year pilot project. The objective of the project was to develop a customized process that combines traffic engineering with public engagement, for prioritizing and programming road safety improvements for pedestrians crossing roadways at signalized and non-signalized intersections within the City of Ottawa. The Pedestrian Safety Evaluation Program process contains the following phases, which all rely heavily on local community involvement: Prioritization or network screening; Diagnosis or investigation; Countermeasures evaluation and programming; and, Monitoring. Analytical tools have been developed to assist staff and the community in the prioritization and countermeasure evaluation phases of the Pedestrian Safety Evaluation Program. Applying this Pedestrian Safety Evaluation Program will help minimize the frequency and severity of preventable collisions involving pedestrians by providing guidance in the selection of cost-effective countermeasures, improving the speed at which a decision can be reached, and improving the accuracy of the decision that is reached. Donald Street and Vanier Parkway, and Carling Avenue and Holland Avenue, were the first two intersections in Ottawa to be reviewed from a pedestrian safety perspective with the help of community associations and residents. The analytical tools and guidelines developed were used to identify pedestrian safety risks and issues. Candidate treatments to mitigate the identified risks were identified and selected. The planned improvements are now in the detail design phase, and construction is expected to begin this spring/summer.

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.
