Influence of Canadian Practices in Developing New Brunswick's Work Area Traffic Control Manual
Bibliographic record
Abstract
In 2008, Opus International Consultants (Canada) Ltd. was retained by the New Brunswick Department of Transportation to develop a new Work Area Traffic Control Manual (WATCM). The WATCM provides a uniform set of traffic control guidelines for all construction, maintenance, and utility work carried out within the right-of-way of any provincial road. One of the Department's main priorities in developing the new manual was to ensure that it incorporated best practices consistent with those applied in other Canadian jurisdictions. This paper presents some of the significant changes made to the new WATCM as a result of an extensive review of existing practices from across Canada. The supporting rationale behind each change is provided, as well as a comparison with current practices contained in other provincial manuals. In some instances, considerable variations amongst particular practices were found to exist. The paper identifies these as potential opportunities for developing national guidelines to help rationalize practices that vary from province to province.

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.
