Leif Rasmussen | 354lbr@gmail.com | Licensed under the GPL V2 The plugin is launched from the LanesPlugin class, which creates a LaneMappingMode instance. The LaneMappingMode instance stores one RoadSegmentRenderer per downloaded way with lane tags. The RoadPiece, Lane, Divider, and RoadEdge classes are all parts of roads, and are stored inside a RoadSegmentRenderer. The Utils class has some nice tools and constants that several other classes need to access.
