Abstract
This paper presents the asset management concepts, engineering standards and technical tools developed by Ministry of Transportation of Ontario (MTO) for highway network preservation and annual investment planning, focusing on the applied standards and specifications including pavement performance measures, prediction models, rehabilitation strategies, cost effectiveness analyses, prioritization and optimization methods. The paper presents how MTO's Second Generation Pavement Management System (PMS2) fits into the ongoing Asset Management (AM) activities in terms of corridor investment plans (CIP) and multi-year rehabilitation and maintenance program. An example application of a corridor investment plan is used to illustrate the key characteristics and functional capacities of the newly enhanced PMS2, including road network database management, performance evaluation and prediction, and customized decision trees based upon forecasted road conditions and targeted service levels. The paper concludes with main findings from the example study of Ontario provincial highway corridor investment plans under different scenarios of investment and targeted performance levels, and discussions on several challenges related to the integration of PMS2 into the asset management program.

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
