Abstract
Existing geometric design guides provide deterministic standards for design requirements primarily based on near worst-case scenarios and conservative percentile selection of design parameters. Probabilistic geometric design analysis has been advocated to represent realistically the randomness in design parameters and variables. Probabilistic techniques can provide a measure of the degree of deviation from design standards. Collision modification factors have been advocated as quantitative measures of the impact on safety associated with changes in road features or traffic control. Often, however, no collision modification factors exist in the literature to predict the safety impact of changing particular road features. An important example is sight distance restriction on horizontal curves. Many highways in British Columbia, Canada, are located in mountainous terrain where the additional cost of earthwork or land acquisition to accommodate lateral road expansion can be prohibitive. In this constrained environment, a typical trade-off arises between design requirements (e.g., adequate sight distance on a horizontal curve) and budgetary constraint. The resolution requires comparing the consequences of every alternative. In these cases, reliability analysis can be used to evaluate the risk of deviating from the design requirements. A decision-support tool was developed to compare the risk of different deviations from sight distance requirements. Two case studies were used to investigate the safety implications of sight distance limitation on road segments, the risk associated with deviation from standards, and risk variations among the road segments. The proposed road design is associated with relatively high risk of limited sight distance, and the risk levels associated with standard design requirements vary significantly.

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
