Abstract
Various performance-based geometric design tools have been developed and used over the past ten years. Most of the tools consider only one aspect, such as safety or sustainability. For highway rehabilitation and new construction projects, an integrated design tool is needed. This paper demonstrates a Network Expansion Support System (NESS) developed by Alberta Transportation in Canada. NESS integrates the geometric design guide, safety and level of service criteria, as well as budget and risk management. It screens highway segments for deficiencies and provides recommendations. With this system, the selected design alternatives will not only meet the geometric design standards but also achieve better network performance. Furthermore, NESS belongs to the provincial Transportation Infrastructure Management System (TIMS), so the recommended highway segment work plans are rationalized with other activities, leading to a more efficient capital work program. This paper presents case studies on project development for highway improvement using NESS. It also demonstrates how TIMS manages the performance of highway networks. Potentially, highway agencies could adopt NESS’ approach in the project development stage to identify geometric design and performance deficiencies.

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
