alles klar, habe ein bisschen Lametta drangehängt.
way/377959070

okay, here is my change:
changeset/35030445

Hallo Marcus,

es geht zwar nur um einen Radweg, aber
die Erfindung einens neuen Tags wie highway=temporarily_blocked
ist nicht nötig. Ich schlage
note="construction is progress"
oder so ähnlich vor, falls es überhaupt sinnvoll ist, kurzfristige Bauarbeiten zu mappen. Siehe auch
osm.wiki/DE:Key:construction

please review: I guess highway=sres meant
highway=residential?
I've changed it to that.
way/377835619

please review way/377847156
I've changed highway=alley to
highway=service
service=alley
changeset/35028416

please review the invalid
tag highway="Cap del Barry"
Not sure what you wanted to change here.
way/161463048

please review: I've changed the invalid tag
highway=residential;unclassified to
highway=unclassified
way/164027708

please review:
the tag highway=track;unclassified
is invalid. Most of the way looks like a highway=track, but those are typically not named. On the other hand, the name
"Chemin du Côteau" appeas also on another way, see way/95853944 and
way/377869093

please review way/57778765:
due to an error in iD you were allowed to merge two ways with different attributes:
bicycle=no;designated
foot=yes;designated
highway=path;footway
surface=dirt;compacted
width=1;2
Please try to fix these invalid tags.
way/57778765

okay, 1st floor means level=1
those road attributes shoud not be added to the node. I see that this happens quite often in this area. If you are looking for a good example:
I think node/3810912268
looks much better.
I don't understand the tag
node_id=*
which is also often used in this area.
The node id is a property of the node in the OSM database, there should be no need to add it as a tag.

great, thanks for the quick reaction

done, next time I just change and post a link
to the changesetto let you know, okay?

please review:
you added a few nodes with "highway=traffic_signals " (trailing blank!)
I've combined them to one in the middle, see changeset/35021571
and
highway=traffic_signals

please review:
is it okay to replace highway=bus_stop_inactive
by disused:highway=bus_stop ?
It is only used in this changeset, see e.g.
node/31112788

please review: is it okay to change
highway=ex_bus_stop to
abandoned:highway=bus_stop ?
The tag is only used 3 times, e.g. here
node/393422352

please review node/2034283521
The tag highway=stud is rarely used, what is meant here?

thanks for the feedback. Do you agree that
we can change it to highway=path ?

OK, thanks for the feedback

please explain:
what does the word CUS in
highway="bus_stop CUS"
mean ?
node/2612760560

okay, change them to highway=proposed
when you think that is better. See also
