Abstract

fetched live from OpenAlex

Ottawa’s first raised cycle tracks were implemented in 2014 on Churchill Avenue and are worthy of the TAC 2015 Sustainable Urban Transportation Award because of the “Complete Street” approach to encourage sustainable and active travel. This $21.4 million integrated road, sewer and water rehabilitation project also included improved (LED) street lighting, traffic control signals, traffic calming measures, concrete curbs and sidewalks, streetscaping, and utilities relocation for this 1.2 kilometre roadway. The Churchill design incorporates uni-directional cycle tracks, raised cycle cross-rides at side streets, and the “protected intersection” concept at two signalised intersections. Implemented as part of a coordinated roadway reconstruction project, the physically separated raised bike lanes are a design solution new to Ottawa and much of North America. The City of Ottawa was the proponent and lead for the project with Novatech acting as prime consultant.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
