town op• Data kinds: table → table
• Call: import fullseye as fs; fs.ledger.town_stop_lines(layout, *, side: 'str' = 'left') -> 'List[dict]' (to call the implementation directly, import drivetown; drivetown.town_stop_lines(layout, *, side: 'str' = 'left') -> 'List[dict]'; from the registry, opsdrive.get("town_stop_lines"))
Lists the town's stop lines in order of arc length: [{"s", "x", "y", "yaw", "kind", "element", "crossing_zone": (s0, s1) | None, "drawn": bool}, ...].
> The detailed description below is the original text — the summary and the headings are translated.
交差点: 要素の stop_lines(線分 (2, 2))のうち 中心線に端点が載り、進行方向の side の側へ延びる物 が走行路の停止線(4 本のうち 1 本。左側通行なら左、右側通行なら鏡像の 1 本)。踏切: 停止線の位置は 踏切面 − stop_setback の閉形式 (drivecourse は左車線にしか白線を描かないので side に依らない。drawn = その側に白線が描かれているか)。s は中心線上の弧長、yaw はそこでの進行方向。踏切は踏切面の弧長の範囲 crossing_zone も付ける。
Raises ValueError: layout が town_chain の物でない、side が left/right でない。
