Abstract

fetched live from OpenAlex

Highway authorities maintain footways in a safe condition following a regime of regular inspections, repairing hazardous defects found and resurfacing at less frequent intervals. The interval between inspections depends on the footway usage, and the reaction time for repairs depends on the hazard posed by the defect as well as the footway usage, reflecting the relative risk of an accident. Currently, these intervals are determined by judgement and this paper describes how the risk can be quantified. Records of third-party claims were examined for factors that influence numbers of accidents, including pedestrian age, defect size and footway construction. Statistics of accidents requiring hospital treatment and the results of medical research into walking provided further insight. By making a number of assumptions, a relationship between risk and defect height was derived. The cost to society of a footway accident was also determined. Thus, for a given footway network and maintenance regime, the likely number of accidents and their cost can be calculated. This enables highway authorities to compare the costs of different maintenance regimes with the benefits of accidents prevented. Collecting further data in a standard format would enable refinement of the model.

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.
