Abstract
This study develops a framework for risk-based decision making for the design, operation, and maintenance of various types of transportation facilities and entities. This framework is grounded in current practice and risk management theories and operationalizes a decision-making framework that is applicable at multiple levels in an organization. The framework defines all crucial steps: technical components of risk assessment, communication logistics, and information systems. The approach is illustrated by two examples. The primary example demonstrates the framework through the context of allocating resources for the inspection and maintenance of a portfolio of signalized mast arms. A qualitative risk assessment method is used, informed by extensive inspection records from the Colorado DOT and finite-element models for mast arms, to recommend varied inspection frequencies based on current structural defects present. A secondary example uses a more quantitative risk assessment approach to inform seismic design decisions for bridges in Colorado. Through the literature review and presented examples, this study develops the resources and information necessary to implement a risk-based methodology in decision making within a transportation agency.

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
