Strongly based on key:smoothness

Provide a very narrow classification scheme regarding the physical usability of a way for wheeled vehicles.

Please see also the FAQ in the talk page's begining

Applies to

highway=* + area (such as amenity=parking, highway=pedestrian)


key:smoothness while still being close in goal to it.

Being more specific

Once this rough guess has been made (that could be well enough for beginners or lazy guys, since it holds in itself the very important question to renderers and routing programs : what vehicle do I need to go there ) users can increase the terrain knowledge with more specific tags :


Proposal usable by : Picture example :
usability=1 (thin_rollers) roller blade/skate board and all below Highway secondary-photo.jpg
usability=2 (thin wheels) racing bike/city bike/sport cars/wheel chair/Scooter and all below Surface grade1.jpg
usability=3 (wheels) trekking bike/normal cars and all below Surface grade2.jpg
usability=4 (robust_wheels) Car with high clearance/off road vehicles/Mountain bike without crampons and all below Jena Trackexample profile cut edges.jpg
usability=5 (off_road_wheels) tractor/ATV/tanks/trial/Mountain bike/Harvester (forestry) Mountain-track5.jpg
usability=6 (impassable) no wheeled vehicles Smoothness impassable.JPG
