track_sight_distance — DRIVE `crossing` op

• Data kinds: any → any

• Call: import fullseye as fs; fs.ledger.track_sight_distance(v_train, clear_time, *, margin: 'float' = 0.0) (to call the implementation directly, import drivecrossing; drivecrossing.track_sight_distance(v_train, clear_time, *, margin: 'float' = 0.0); from the registry, opsdrive.get("track_sight_distance"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

渡り切る前に列車が着かないために、線路の上で見えていなければならない距離 = v_train · (clear_time + margin)。

見える距離がこれ以上なら、見えていない列車は渡り切る前に踏切に着かない(到達時刻 = 距離 / 速さ > 渡り切る時間)。配列可。
