92 Avenue (Edmonton) Arterial Roundabouts: Collaborative Concept Development
Bibliographic record
Abstract
This paper describes the process, challenges, lessons learned, and cooperation required between the Developer, City and Consultant to develop an innovative and context sensitive concept plan for a developer-initiated 1.6km arterial road in a new growth area in west Edmonton (Secord and Rosenthal Neighbourhoods). The approved plan includes five roundabout intersections, reduced lanes and right-of-way width, and is anticipated to provide superior operations to a conventional four-lane divided arterial roadway with signalized intersections. It has been common practice in Edmonton for Developers to be involved in the design and construction of arterial roads. However, typically concept (functional) planning has been completed by or under the direction of City staff. Strong growth in Edmonton has accelerated demand for new arterial roadways, stretching City planning resources. To meet the demand for planning of arterial roadways in new growth areas, the City recently implemented a process where planning of arterial roads in new areas can be completed by the Developer’s Consultant(s), supported by a City approval process. The desire for Consultants to be innovative and develop new approaches to planning arterials is often stifled by the desire to obtain quick approvals, which are most easily achieved by maintaining the status quo, applying existing standards, and generally not looking outside-the-box for more context-sensitive design solutions. While undertaking the 92 Avenue planning study between 215 Street and 231 Street in Edmonton, Al-Terra Engineering Ltd. identified early on that the arterial was an ideal candidate for an alternate approach. Since the bordering lands were primarily residential, including a large district park, a context-sensitive design was desirable to promote lower traffic speeds and create a pedestrian/bicycle friendly environment. Al-Terra Engineering Ltd. was afforded the rare opportunity by their client, MLC Group Inc., to challenge the status quo and develop an arterial roadway incorporating several roundabout intersections. Although cautious of the alternative design solution, the City provided support and assurances that if the design could be technically supported they would provide due consideration and work with the Consultant to advance the alternate design through to approval. Although the concept planning process took longer than usual due to the detailed reviews required and the educational aspects of the planning study, the plan was recently approved by the City of Edmonton. The Developer, Consultant, and City successfully collaborated to develop a context-sensitive, alternative design solution for this new arterial roadway.

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.
