BECOME APPROPRIATE TO LOWER THE TARGET HEIGHT FROM 115 CM TO 60 CM TO CORRESPOND WITH THE MINIMUM HEIGHT STANDARD FOR HEADLIGHTS.
Bibliographic record
Abstract
analysis of the operational impacts associated with changing the design criteria for marking no-passing zones on two-lane rural highways. The research explored the premise that the striping guidelines, defined by the manual of Uniform Traffic Control Devices for Canada (UTCD), 1 should be changed to reflect a lowered target height equivalent to the standard minimum height2 for passenger vehicle headlights of 60 centimeters (cm). Consequential reductions in passing opportunities and changes in operational service levels were quantified. An underlying assumption of the research was that as daytime running lights (DRL) become more prevalent, drivers will grow more accustomed to identifying oncoming vehicles by the presence of DRLs before initiating passing maneuvers. The current target height assumes that a driver can detect an oncoming vehicle if at least the windshield/roof is visible. Since 1989, Transport Canada has regulated that all vehicles sold in Canada must be equipped with DRLs. 3 The minimum height standard for DRLs is 38 cm as dictated

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.
