Abstract

fetched live from OpenAlex

Traffic congestion is an existing problem in North Toronto with Highway 401 and other area roads operating at capacity during peak hours. Future population and employment growth across north Toronto will increase traffic demands in the area. With many roads already operating at capacity, alternative non-auto modes of transportation will be required to accommodate future traffic demands and minimize future traffic congestion. Public transit is the best means of providing a non-auto transportation mode in north Toronto. Higher-order rapid transit can offer travel-time savings and many other benefits over auto-travel in congested conditions; however, no rapid transit service presently exists across north Toronto. This paper provides the rationale for a north Toronto rapid transit line and confirms its feasibility for its implementation.

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.

Not 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.
