Agreed. I think option 2 is the right path. primary used to mean important long-distance route, before people started calling local roads primary. Long term, it would be nice to separate these notions and have some highway:importance key for that, and leave the road type notion that separates primary/trunk/motorway alone (or move it to some other tag, and get rid of highway=trunk and highway=motorway). As for the freeway/expressway notion, note that this is regional langauge and we don't walk that way in Boston (we're too busy running red lights and using our horns!!). But seriously, I don't know those distinctions and people don't really use those words. I guess you are suggesting to add highway=expressway to have expressway mean "sort of motorway but not quite" and change trunk to be "very important". I am afraid that with so much established tagging the only reasonable approach to orthogonalization is to adopt two new tags for the things in question and deprecate the old way, allowing for a long and messy transition. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
