Abstract
The impact of traditional safety warnings can be reduced because they tend to be rather static. This article describes some dynamic messaging systems, which are vehicle-specific and can be much more effective. Dynamic messaging uses a variety of input data to display appropriate messages. The safety systems developed by the Canadian company International Road Dynamics (IRD) operate on the principle that drivers are more likely to react to messages that are directed specifically to them and based on real danger. Weigh-in-motion (WIM) technology can be used to identify the traffic segment at risk, and this approach has been applied successfully to motorway exit ramps, long downgrades, and junctions at the foot of a steep slope. Simpler vehicle detection technology has been applied to traffic safety problems associated with work zones and animals on the road. The article describes the following four products of IRD: (1) Downhill Truck Speed Advisory System, which uses WIM information to calculate and display a safe speed down a hill for each individual lorry; (2) Truck & Rollover Advisory System, which determines when there is a possibility of overturning; (3) Signal Pre-emption System, which triggers a green light when it detects a runaway vehicle; (4) Dynamic Work Zone Safety System; and (5) Wildlife Warning System.

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.
