Abstract

fetched live from OpenAlex

The safety impacts of improving pavement skid resistance were examined in this study by using data from New York State. The New York Department of Transportation runs a skid-accident reduction program that identifies sections of pavement with a high proportion of wet-road accidents, friction-tests these locations, and treats those with both a high proportion of wet-road accidents and low friction numbers. An empirical Bayes before–after study was conducted of locations that were treated under this program. The results indicate that this can be a highly cost-effective safety treatment for both intersections and road segments that warrant skid resistance improvement because of a high frequency of wet road accidents and low friction numbers.

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.
