Parametric Fitting
📌 Brief Overview: Parametric fitting is a data‑driven approach that adjusts geometric design parameters (e.g., vertical curves, grades, edge offsets) to optimally match existing ground conditions while meeting design standards. It enables rapid iteration and fine‑tuning of alignment to improve ride quality, reduce earthwork, and preserve surrounding features.
- Improve vertical profile and ride quality
- Match design edges to existing
- Design sequence iterations
✅ Why it matters: By automatically testing multiple design variables (such as K‑values for vertical curves, edge matching thresholds, and superelevation rates), parametric fitting helps engineers quickly find the best balance between safety, comfort, and construction cost — without manual trial‑and‑error.
