please review:
maxspeed="40 kph"
Is that 40 mph or kmh ?

thanks for the quick feedback.

I would use
highway=pedestrian or highway=footway with area=yes for this.
Which routing software supports way=yes?
It is rarely used.

please review:
what is meant with way=firewall ?
Maybe
man_made=cutline ?
man_made=cutline
In Bing the way looks more like a normal
highway=track now.

please explain;
what does
way=60708167
mean?
way/294027837

please review:
It seems you wanted to create a
type=multipolygon relation, but something went wrong.
See my changes to fix this:

please explain:
what is meant with
way=yes ?
way/278365183

please explain:
what does way=yes mean ?
way/267875373

please review:
What does
way=yes mean ?
way/263170655

please review:
I've changed way=residential
to
highway=service
service=driveway

please review:
what is meant with
way=pedestrian tunnel ?
If there is a way through the building
you may add that with
highway=footway
tunnel=building_passage

way/62343104

please review:
This seems to be an indoor elevator ?
node/3185979548
The node should be tagged with
highway=elevator, the way(s) from and to it
with highway=footway / corridor

please review:
you have added some tags with
higway=residential instead of highway=residential in this area.
I've changed them to highway=residential.
OK?

please review
way/20132873
This doesn't look like a
highway=escape to me.
Seems to be a road that help to do a u--turn?
highway=escape

please review:
the tag highway=island is rarely used,
it seems you use it instead of traffic_calming=island ?
way/355256471

please review:

please review:
what is meant with highway=unbuilt?
The tag is rarely used and typically means
that there is no way at all.
way/308512483
Is is some kind of desire path?

please review:
I've replaced the tag
highway=unbuilt by a note
to make sure that routing software is not confused. Do you have further information why you mapped the ways?
E.g.
way/124826150

bitte prüfen:
Ich habe das tag highway=unbuilt entfernt,
damit nicht doch irgendeine Routingsoftware
das verwechselt.
