UBC Chancellor Boulevard & East Mall Intersection Redesign
Bibliographic record
Abstract
This report outlines the detailed redesign of the intersection at Chancellor Boulevard and East Mall, at the University of British Columbia. The current intersection does not promote safety, user friendliness, nor does it meet the future anticipated traffic demand of the growing UBC campus. The new intersection design aims at mitigating these issues by placing a roundabout at the intersection. Meanwhile, at the southeast corner of the intersection, a pedestrian lookout platform was designed and detailed within the report. The report begins with discussing the project background information and overarching objectives. It then examines the technical standards governing the design, the software programs used, and the final detailed parameters of the design components. Lastly, the report concludes by presenting the refined cost estimates, construction schedule, work sequence, and additional environmental, stormwater, and First Nations considerations. The new roundabout shall replace the current two-way stop-controlled intersection, creating a safer and more disciplined travelling environment for its users. The City of Vancouver predicted that by 2030, over 66% of city’s transportation would be through sustainable transport, hence the roundabout has been designed for not only regular drivers, but also the rapidly growing number of pedestrians, cyclists and public transit users. The pedestrian lookout platform near the intersection will serve as an iconic landmark and provide an inviting gateway into the UBC campus. It has been designed to offer full wheelchair accessibility and optimum safety during any severe storm or seismic events. In addition, the consultant also investigated the existing stormwater management strategies in this region, and detected potential risks of flooding and cliff erosion on the north perimeter of the campus. In response, it is highly recommended that a subterranean detention tank along with perforated drainage pipes be installed directly east of the intersection. Project construction is set to begin on May 2nd 2016 and will extend until August 18th 2016. A detailed construction schedule and work required are presented in the report, as well as a phased traffic management plan (sensitive to high traffic events). Overall, the roundabout is expected to cost $980,140, and the pedestrian platform, $362,250.

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.
