As a supplement to this discussion, I would like to mention the proposed
"separation" scheme that we have been experimenting with in Berlin for
some time:
https://wiki.openstreetmap.org/wiki/Proposed_features/cycleway:separation
(former "protection").
It is mainly intended for mapping Protected Bike Lanes and similar types
of cycle paths, but can also be used to classify lane markings
(especially solid and dashed lines, but also special forms like
pictogram/surface symbolisations).
In my opinion, it should be possible to extract all the information from
(1) the lane class (lane, track), (2) this type of marking and (3) the
signage (designated access or traffic sign) in order to be able to make
a statement about accessibility for other vehicles, compulsory use etc.
in connection with the country and its laws – thus there would no longer
be a need to record an "interpreted" value such as "cycleway:lane", but
rather everything can be extracted from attributes that can really be
seen on the ground without having any knowledge of the law.
