Hello ! I've been thinking about this for a long time.
Classifying roads should be the same all over the world ! :O The highway tag shuffles administration grade (in England for example or for motorways), physical characteristics / abutters (example : residential, motorway), access, and importance (commuting and long-distance trip). I think the highway tag should be split into those 5 features : admin_level, abutters, access, commute_importance and long_distance_importance (by experience, there should be 6 levels for importance, from the cul-de-sac road to the main artery). Importance tags could also apply to bicycle path and footways :D Julien "djakk" Le sam. 10 août 2019 à 10:27, Joseph Eisenberg <joseph.eisenb...@gmail.com> a écrit : > > We recently discussed the confusion about unclassified vs residential > recently, but a more significant issue is that different countries and > regions have a wide variety of practices about assigning the major > highway classes, especially trunk and primary. > > In some countries, including parts of Europe and parts of the USA, > highway=trunk is reserved for "expressways" or "motorroads" with > certain physical characteristics.
