Abstract
A vital component of asset management, performance measurement is used in planning and programming to identify assets and/or processes that are over/under performing. As part of the move to asset management, Alberta Transportation has implemented performance based planning and monitoring of the provincial highway network and three performance measures, based upon technical measurements, are used. These measures relate to network condition, functional adequacy and utilization. Although Alberta, like the rest of Canada and much of North America, is a winter province, no clear suite of performance measure has been developed for monitoring the effectiveness of snow and ice control measures during winter weather events. Traditionally, agencies have measured inputs (such as salt or sand) or outputs (such as plowing frequencies), but none of the existing measures address effectiveness. Using data from weigh-in-motion (WIM) sensors and regional weather data from Environment Canada, the effect on mean vehicular speed of various winter events was determined at six sites across the provincial highway system. Reduction in vehicular speed and the duration of the speed reduction (time to recovery) were calculated for five event types and differences noted. The methodology developed shows promise for future development of robust, repeatable and easily understood performance measures that can be used to monitor winter events and to develop future benchmarks.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
