Abstract
This paper describes the development and implementation of a specification for nighttime highway construction & maintenance projects in Nova Scotia. The paper will deal with the details of the specification and the lessons learned in the first project in which it was used during the summer of 2002. Increasing traffic volumes and the demand from the motoring public to minimize delays at work zones throughout North America have led to the scheduling of some highway maintenance and construction activities to nighttime hours. A major cold planning and re-paving project on one of Nova Scotia’s busiest highways during the summer of 2002 had to be carried out during the night to avoid imposing excessive delays on motorists. A literature search, discussions with most state and provincial agencies, and research data from the Transportation Research Board and other sources were used in the development of the specification. Discussions with other provinces indicate that this may be the first comprehensive nighttime work specification by a Provincial Transportation Agency. The project was carried out during the summer of 2002 and the specification proved to be achievable and to meet our Department’s expectations. Detailed observations made during this initial project will be used to revise the specification for use on some projects in 2003.

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.
