Tagging considerations are not "for the renderer", it's about how the world can be abstracted to be stored in such a way that the information you are interested in can be found in the data. Regarding the "forward" and "backward" roles for way members of routes: they refer to the direction of the way (member), not to the direction of the relation. If you want to map a route which goes from A to B it will typically be different from a route that goes from B to A (because of dual carriage ways and other (even short) oneway roads (like links, ramps) , etc.), and the solution is to map 2 routes and eventually connect them with a route master. https://wiki.openstreetmap.org/wiki/Relation:route_master Cheers, Martin
