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"))
Position (angle traveled clockwise) at which to start the left turn signal when exiting a roundabout. Scenario S069.
Rules of the Road (Japan) 5-5-1(2), 5-7-2(4): when passing beside the exit immediately before the point where one intends to exit; to leave by the exit immediately after entering, upon entering (Article 53, paragraph 2, Road Traffic Act (Japan); the cabinet order on timing = Enforcement Order Article 21 is unverified). arm_angles = angle of each arm, entry / exit = indices. Angle of each arm measured clockwise from the entry d_i = (θ_entry − θ_i) mod 2π (2π if exit = entry, U-turn). Signal angle = the largest d_i smaller than the angle of the target exit (0 if none = upon entering). Returns: signal_angle, exit_angle, exits_before (number of exits passed), signal_theta (angle on the ring road).
