lane_change_permitted — DRIVE pass op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.lane_change_permitted(*, follower: 'Optional[dict]' = None, boundary: 'str' = 'none', exception: 'Optional[str]' = None, signal_events: 'Optional[Sequence[dict]]' = None, sudden: 'float' = 2.0) -> 'Dict[str, object]' (to call the implementation directly, import drivepass; drivepass.lane_change_permitted(*, follower: 'Optional[dict]' = None, boundary: 'str' = 'none', exception: 'Optional[str]' = None, signal_events: 'Optional[Sequence[dict]]' = None, sudden: 'float' = 2.0) -> 'Dict[str, object]'; from the registry, opsdrive.get("lane_change_permitted"))

Usage

Whether a lane change is permitted (judgment by the statute). Scenarios S067, S072, S073.

> The detailed description below is the original text — the summary and the headings are translated.

• follower_sudden_decel(26 条の 2 第 2 項): follower = {"gap", "v_follow", "v_ego", "reaction"[, "accel_ego", "min_gap"]} に lane_change_follower_decel で要る減速度が sudden を超える。

• no_lane_change_marking(26 条の 2 第 3 項): boundary = "yellow"(進路変更の禁止を表示する道路標示)を越える。exception = "article40"(緊急自動車に譲る)/ "obstruction"(道路の損壊・工事その他の障害)なら除外(同項 1・2 号)。

• signal_*(53 条 1 項・教則 5-5-1「約 3 秒前」): signal_events を drivedecide.check_sequence_score (maneuver="lane_change")で採点した違反をそのまま足す(施行令 21 条は未確認)。

26 条の 2 第 1 項「みだりに」は数値にできないので判定しない。返り値: ok、reasons、decel、sequence。
