crossing op• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.crossing_timing_check(t_warning, t_closed, t_arrival, *, timing: 'Optional[dict]' = None) -> 'Dict[str, object]' (to call the implementation directly, import drivecrossing; drivecrossing.crossing_timing_check(t_warning, t_closed, t_arrival, *, timing: 'Optional[dict]' = None) -> 'Dict[str, object]'; from the registry, opsdrive.get("crossing_timing_check"))
> This operator's description has not been translated yet. The original text follows as it is.
踏切の 3 つの時刻(警報開始・遮断動作の終了・列車の到達)を解釈基準の標準と最小に照らす(配列 = 列車ごと)。
警報→到達の 30 / 20 秒は解釈基準 5(3) の踏切警報機(遮断機なし)の値。遮断機のある踏切では 4(3)(5) の 2 つ
(15 + 20 = 35 秒が標準)が効き、30 / 20 秒の側は自動的に満たされる。
返り値: `warn_to_closed / closed_to_arrival / warn_to_arrival(各 [s])、meets_minimum`(3 つとも最小以上)、
`deviation(標準からのずれ、3 つ)、spread`(列車ごとの警報開始→到達の最大 − 最小。解釈基準 5(4)「速度等により
大きく異なるものでない」の量)。時刻の順が逆(遮断終了が警報より前など)は ValueError。
