  "about": "Changes we make to OpenStreetMap data when we build our road graphs. A rule applies to every graph edge whose name is listed and whose midpoint lies inside bbox [west, south, east, north], or, with \"within\", to every drivable edge inside the named OpenStreetMap park. \"set\" adds flags: busonly and park both add noaccess, so the road is drawn with red stripes and a route on it is marked as not allowed. \"clear\" removes flags.",
