course op• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.course_crossing(width=7.0, gauge=1.1, rail_outer=0.75, approach=6.0, stop_setback=0.5) (to call the implementation directly, import drivecourse; drivecourse.course_crossing(width=7.0, gauge=1.1, rail_outer=0.75, approach=6.0, stop_setback=0.5); from the registry, opsdrive.get("course_crossing"))
Railroad crossing: a track crosses a road of width w (along the x axis) at a right angle. Straights of length approach lie on both sides of the crossing surface (gauge + 2 outer rail strips = 2.6 m). rails (2, 2, 2) are the segments of the 2 rails (x = L/2 ± gauge/2, across the full road width), crossing_zone = (x0, x1) is the crossing surface, stop_lines (1, 2, 2) lies in the left lane stop_setback before the crossing surface. The polygon is a rectangle (the rails are metadata). Standard: gauge 1.1, outer rail strip 0.75 → params["regulation"]. Area = w·(2(rail_outer + gauge/2) + 2·approach).

Raises ValueError: 幅・軌間・approach が正でない、rail_outer < 0、stop_setback < 0。
