Abstract

fetched live from OpenAlex

Although in-pavement LEDs at crosswalks are commonly used in regions with favourable climates, they have yet to be tested in a typical Canadian winter. In 2003, the City of Airdrie initiated a pilot project with the first generation of in-pavement LEDs. Although driver and publis respose was favourable, snowplows and streetsweepers have damaged the lenses on these LEDs to the point they were not functioning as intended. A different system was installed at two intersections in October 2007, and as of March 2008 no damage has been noticed from winter miantenance activities (plows and sanders). This project was nominated for the 2007 TAC Road Safety Engineering Award.

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.
