道路網から日本の町の 3-D 世界(driveworld 形式)を組む。
路面 = 全体の格子平面(z 0、ラベル 0)。道路の和集合の 穴 = 街区: 歩道の面(z = kerb_height、ラベル 15)と縁石の帯(ラベル 1)。
外側の縁にも縁石。車線の印(ラベル 9): 2 車線の両方向路は中央線を白の破線(5 m / 5 m)、4 車線以上は実線、車線境界は破線。交差点では
他の辺の半幅ぶん印を切る。`props なら節点の特徴に: 信号機(traffic_signals`、進入する辺ごと、交差点の向こう側・左)、横断歩道
(`crossing、進行方向に平行な 0.45 m の縞、ラベル 12)、一時停止(stop / give_way`: 標識 + 停止線 + 「止まれ」、進入する辺ごと)、
踏切(`level_crossing`: 2 本のレール(ラベル 8)+ 踏切警標 + 停止線)。生活道路(residential / unclassified / living_street)の
通行側の縁に `pole_pitch 間隔で電柱(ラベル 16)。buildings` = plateau_parse の建物の列なら押し出し柱(ラベル 14)。
返り値 = driveworld の世界 + `{"graph", "roadmask", "loops", "signals": [{"node", "edge", "object", "pose"}], "stats": {...}}`。
Raises `ValueError`: side が left/right 以外、kerb/step が不正。
