Planning of an Unconventional Urban Arterial Intersection - A Context Sensitive Approach
Bibliographic record
Abstract
Calgary's population has recently exceeded the one million mark. Many of the City's intersections are now at capacity, and desperately need improvement. One of the busiest intersections in Calgary is Macleod Trail and 25 Avenue SE. Macleod Trail is an important north-south arterial road, with an average daily traffic (ADT) of 53,000 vehicles trips per day (vpd). 25 Avenue is an east-west through road with an ADT of 17,000 vpd. Major arterials in built-up urban areas face problems not necessarily present in typical freeway-type interchange design. In such built-up areas, there is usually insufficient room for the construction of expansive loop ramps. Maintaining the existing flow of traffic during implementation is another critical consideration. The proximity of existing commuter transit and/or freight rail lines is often an added constraint. The paper outlines some of the unconventional options considered in the functional design of the interchange, and attempts to rationalize a methodology of alternative selection using a context sensitive design approach.

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.
