roundabout_signal_point — DRIVE pass op

• Data kinds: any → table

• Call: import fullseye as fs; fs.ledger.roundabout_signal_point(arm_angles: 'Sequence[float]', entry: 'int', exit: 'int') -> 'Dict[str, object]' (to call the implementation directly, import drivepass; drivepass.roundabout_signal_point(arm_angles: 'Sequence[float]', entry: 'int', exit: 'int') -> 'Dict[str, object]'; from the registry, opsdrive.get("roundabout_signal_point"))

Usage

Position (angle traveled clockwise) at which to start the left turn signal when exiting a roundabout. Scenario S069.

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

教則 5-5-1(2)・5-7-2(4): 出ようとする地点の直前の出口の側方を通過したとき、入った直後の出口を出るなら入ったとき(53 条 2 項。時期の政令 = 施行令 21 条は未確認)。arm_angles = 各枝の角、entry / exit = 番号。右回りに入口から測った各枝の角 d_i = (θ_entry − θ_i) mod 2π(出口 = 入口なら 2π、転回)。合図の角 = 目的の出口の角より小さい d_i の最大値(無ければ 0 = 入ったとき)。返り値: signal_angle、exit_angle、exits_before(通り過ぎる出口の数)、signal_theta(環道の上の角)。
