design_min_radius — DRIVE `lateral` op

• Data kinds: any → any

• Call: import fullseye as fs; fs.ledger.design_min_radius(design_speed_kmh, *, side_friction: 'float', superelevation: 'float') -> 'np.ndarray' (to call the implementation directly, import drivelateral; drivelateral.design_min_radius(design_speed_kmh, *, side_friction: 'float', superelevation: 'float') -> 'np.ndarray'; from the registry, opsdrive.get("design_min_radius"))

Usage

道路構造令の解説 (3) 式の最小曲線半径 R = V² / (127 (i + f)) [m] (V は km/h)。

(2) 式から分母の i f を落とし(i f ≪ 1)、3.6² g ≈ 127 とした設計の式。厳密な上限速度は :func:curve_speed_limit。

Raises `ValueError`: V ≤ 0、f < 0、i + f ≤ 0。
