occlusion_safe_speed — DRIVE `traffic` op

• Data kinds: any → any

• Call: import fullseye as fs; fs.ledger.occlusion_safe_speed(d, *, reaction: 'float', brake: 'float') (to call the implementation directly, import drivetraffic; drivetraffic.occlusion_safe_speed(d, *, reaction: 'float', brake: 'float'); from the registry, opsdrive.get("occlusion_safe_speed"))

Usage

Maximum speed at which the car can stop within distance d from the moment of becoming visible: v = b(−ρ + sqrt(ρ² + 2d/b)).

v ρ + v²/(2b) = d(空走 + 制動。rsssafety.rss_stopping_distance(v, ρ, accel=0, brake=b) と同じ式)を v について解いた正の根。桁落ちを避けて v = 2d / (ρ + sqrt(ρ² + 2d/b)) で計算する(ρ = 0 で sqrt(2 b d))。d は配列でもよい。d ≤ 0 なら 0(見えた時には既に間に合わない)。

門: rss_stopping_distance(v, ρ, 0, b) == d(第 2 実装、rtol 1e-12)。

Raises ValueError: reaction < 0、brake ≤ 0、d が非有限(inf は許して inf を返す)。
