Implications of Stagnant Reporting Thresholds for Motor Vehicle Collisions
Bibliographic record
Abstract
Each Canadian province and territory has laws requiring the reporting of vehicle collisions to enforcement agencies when there has been an injury, fatality or property damage of a specified extent. In most jurisdictions, including New Brunswick, the reporting threshold for Property Damage Only (PDO) collisions is $1,000 in total collision damage; however, the Canadian Council of Motor Transport Administrators (CCMTA) recently endorsed moving to a $2,000 reporting threshold for inclusion of PDO collisions in the National Collision Database. The collision reporting threshold was last adjusted in New Brunswick in 1993 (up from $400 in place since 1980). This paper explored the impact of the static $1000 reporting threshold on the inclusion of collisions in the New Brunswick collision database from 1994 – 2008 in terms of current and constant (1994) dollars, as well as implications for the availability of collision data in moving to a $2,000 or $4,000 threshold. Recommendations include developing uniform, objective criteria for assessing PDO collision severity.

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.
