Abstract

fetched live from OpenAlex

This national report is based on a larger study being undertaken through the Civil Engineering Graduate Program at Carleton University in Ottawa, Ontario Canada. This report focuses on fatal, injury, and property damage collision data collected from Transport Canada's Traffic Accident Information Database for the years of 1984 to 2003. A 20-year collision analysis was compared with a 5-year analysis from 1999 to 2003 in order to compare long-term trends with more recent ones and to identify specific collision characteristics that require attention. Based on the results of the two analyses, a number of countermeasures were recommended for consideration to improve road safety on Canadian roads. For the covering abstract see ITRD E139491.

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.
