Tracktype is a measure of how well-maintained a track or other road is, particularly regarding surface firmness. It usually applies to highway=track but is often used for non-tracks too, especially in less-developed places where many main roads are unpaved. The proposal from which this key originates may be found at Proposed features/grade1-5. The proposal was voted on, but was standardised primarily because of its widespread use.

surface=* refers to surface material and sometimes to material structure. It may suggest a track type sometimes, but because the same surface material/structure can exhibit various degrees of firmness, it is still advisable to add tracktype=*.

smoothness=* in addition provides a classification scheme regarding the physical usability of a way for wheeled vehicles.

How to map

tracktype=* is primarily used in combination with highway=track (around 96% of uses) but it has also noticeable usage on highway=service, highway=path, highway=unclassified. This tag is useful to provide info about road quality, especially for unpaved roads.
