roundabout_signal_check — DRIVE pass op

• Data kinds: signal × signal → table

• Call: import fullseye as fs; fs.ledger.roundabout_signal_check(progress, left_on, *, arm_angles: 'Sequence[float]', entry: 'int', exit: 'int', right_on=None, tol: 'float' = 0.05) -> 'Dict[str, object]' (to call the implementation directly, import drivepass; drivepass.roundabout_signal_check(progress, left_on, *, arm_angles: 'Sequence[float]', entry: 'int', exit: 'int', right_on=None, tol: 'float' = 0.05) -> 'Dict[str, object]'; from the registry, opsdrive.get("roundabout_signal_check"))

Usage

Scores signaling inside a roundabout (Art. 53(2) and (4), Rules of the Road (Kyosoku) 5-5-1(2)). Scenario S069.

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

progress = 入口から右回りに進んだ角 [rad]、単調非減少、サンプルごと、left_on / right_on = 合図の状態(bool)。

• left_late: 合図の角 + tol から出口の角までの間に左の合図が消えているサンプルがある。

• left_early: 合図の角 − tol より手前で左の合図が点いている(手前の出口で出るように見える。53 条 4 項の「行為をしないのに合図」の 解釈)。入った直後の出口(合図の角 = 0)では問わない。

• right_signal: 環道の中で右の合図(53 条 2 項は出るときだけを求める。4 項の 解釈)。
