Curb the Danger: a police-community collaboration to ‘curb’ impaired driving
Bibliographic record
Abstract
The Edmonton Police Service launched its Curb the Danger (CTD) program in 2006. CTD aims to increase community participation in the real-time detection and apprehension of impaired drivers by encouraging citizens to call 9-1-1 if they observe a suspected impaired driver. This study provides a description and evaluation of CTD. The findings, based on police data and survey results, show CTD has led to an increase in citizen reports of suspected impaired drivers and is a major source of impaired driving charges. The results suggest that community–police collaboration can be effective in impacting impaired driving. Implications for police resource deployment are discussed.

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.
