Abstract
In 2023, Northern Policy Institute published a report concluding that 2+1 roads offer a more cost-effective approach to upgrading major highways in Northern Ontario than highway twinning. 2+1 roads are three-lane roads with one lane in each direction and a passing lane alternating direction every few kilometres, along with a median barrier separating the two directions of traffic. The 2+1 model offers similar safety benefits to highway twinning but is less expensive because it does not require the construction of a second, parallel road. By offering more frequent and safer passing opportunities and reducing the number of road closures due to collisions, 2+1 roads can also improve traffic flow on transportation routes that are critical for rural and northern communities and national supply chains. Tested and proven internationally, 2+1 roads can represent the ideal road configuration on highways across rural and northern Canada where traffic levels are too high for a two-lane road but too low to justify the cost of a divided, four-lane highway. Drawing on the NPI publication, this presentation will discuss how 2+1 roads work, their advantages over alternative road configurations, and the locations where they tend to work best.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
