Road data extracted and changed for the levels of Road Sign Hero (iOS). One JSON file per level. Coordinates are metres on a local plane (origin in each file).
Changes: routes cut to drivable stretches, corners and widths smoothed, points thinned, elevation added, signs/signals placed by MUTCD rules where OSM has none (see "flags").
