<p>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:
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/Proposed_features/cycleway:separation">https://wiki.openstreetmap.org/wiki/Proposed_features/cycleway:separation</a>
(former "protection").<br>
</p>
<p> 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).<br>
<br>
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.</p>

<pre class="moz-quote-pre" wrap="">OK, let's take this up again.
I think we can live with the advisory lane if we agree that this means cars
are advised to keep out.
But, this must be a new value, not a sub:value.
For the very simple reason that there is no way of adding
cycleway:lane=exclusive to the existing 500k cycleway=lane and variants
like cycleway:right|leftboth=lane, in order to distinguish them from the
new lane-sub-type.
I suspect that many advisory lanes are tagged as traditional "full" lanes.
On the French Bicycle wiki page they describe the tagging of their
Chaucidou roads, which have soft or advisory lanes on both sides with
simple cycleway=lanes tag.
So it will in any case be a national scheme, bout which I am not terribly
happy.

In it, you will also find the reasons why cycleway=soft_lane was ruled out.

<pre class="moz-quote-pre" wrap="">The problem is that all over Italy funding is available for these
"cheap" cycle lanes (they do not need any vertical signposting, just
paint on the asphalt)
We need to map them in OSM, and we need to map them differently from the
"classical" bicycle lanes. With my hat as active member in a cyclists'
association, I see a need to distinguish between the two types, because
they are legally very different (and in the view of many also even more
dangerous than the old types, simply because they are much narrower,
less visible and legally open to be used by cars.
The other thing is that we have two different keys in the database. One
as part of an rejected proposal, the newer one was inserted in the wiki
after an inconclusive discussion in the German OSM forum.
The older (rejected) proposal cycleway=soft_lane has the advantage over
the newer cycleway:lane=advisory|mandatory in the sense that it does not
have the need to retrofit the "mandatory" on the non-advisory lanes. It
would create an additional cycleway class and not a new subclass of the
lane class of cycleways.
This would work in Italy, as we did not have soft lanes until a couple
of months ago.
Other countries. like the Netherlands and Germany have had this type of
soft lanes already for many years. This may pose the problem that many
(all?) soft lanes have been tagged as normal lanes.

I have the same understanding,
even though I've never seen this traffic sign.

In italy. or you have a global knowledge ?
So 2 issues :
- improve the wiki
- 14 objects in Italy :) start an editor and fix it :)
you could also propose a validation rule for iD and josm
so the user receives a warning before uploading
