OK, looks good now, if that's really a round about. Bing shows a normal junction, but other area images show white paint on the road that look like a wheel.No idea which image is newer, and I am not a local.

Sorry, link to changeset was wrong, here is the right one:
changeset/37430903

Hi there!
You changed a highway=pesdestrian to
highway=not:pesdestrian +
note="no safe crossing to this area"
Still, I think it looks like a highway=footway and should be tagged like that. If you are sure that the way is not meant for any traffic, please don't use the highway tag.

Sorry, forgot the link to the way:
way/399478995

Hi there!
I've noticed this change because you used highway=crossing instead of highway=footway + footway=crossing. The tag highway=crossing should be used for the node that is shared by the footway and the major road.
I did not change it because I am not a local and Bing doesn't show if the way is really sharing a node or if it goes below / above the highway=bus_guideway

Hi there and welcome to OSM!
I've noticed this change because you used highway=unpaved instead of surface=unpaved. Please highway e.g. highway=footway or highway=residential for the road type and the surface tag for the surface. See also
highway=*
and surface=*

Hi there!
You use highway=unknown instead highway=road for two ways, was that intended?
See way/399707039 and
way/399707038
They look like highway=service roads to me.

Hi there!
I've noticed this change because of a typo:
highway=residentials
used for an area which looks like a squarish turning_loop. Please review my changeset:
way/399701005

Hi there and welcome to OSM!
I've noticed this change because you use highway=crossing for the footway
instead of highway=footway + footway=crossing. The tag highway=crossing shoud only be used on the node whch is shared by the footway and the major road.

Hi there!
You changed a highway=primary to the undocumented highway=mini_roundabout, this will lead to routing problems. Please note that
highway=mini_roundabout is only for nodes.
The area enclosed by the way itself seems to be too large as well, according to Bing.
I sugest to make it smaller and tag it highway=primary + junction=roundabout and maybe a note=no physical obstacle.

Hi there!
Please check:
highway=passing_place used on this way:
way/399215602
I guess it is a typo and you meant highway=path instead ?
I've changed it to that.

Hi there and welcome to OSM!
I've noticed that you mapped four roads for busses with highway=*. I've changed those to highway=service. I guess you found this in the wiki, please note that highway=* always is a placeholder, means, you should use primary,secondary etc. instead of the * .
My changeset is here: changeset/37361180

Hi there!
Please review highway=TR
on way/398789497
I guess you meant highway=track but it looks more like a residential or unclassified road to me.
What is correct?

Moin!
Du hast hier einen (korrekten) Knoten mit
highway=turning_circle durch einen (viel zu großen) Kreis mit highway=turning_circle anstatt residential
ersetzt und dabei versehentlich den ganzen Weg total verschoben. Ich habe das gerade rückgängig gemacht, siehe
changeset/37360808
und osm.wiki/DE:Tag:highway%3Dturning_circle
OK?

OK, wirst Du die entsprechenden Änderungen machen?

Hi there and welcome to OSM!
I've noticed this changeset because you used highway="residential road" instead of just
highway=residential, e.g. here:
way/398393596
You also used it in other place(s), so I thought I contact you. See also
highway=*

Hi there!
I've noticed the highway=fixme:
way/371216260
I am not a local, but the aerial image
looks like a highway=service
which should continue onto the school yard with a barrier=gate node where it ends now.

alles klar, danke für die Rückmeldung

Hi there!
I've changed the typo highway=sre to service:
way/21196264
Bing shows this road somewhere else, is it outdated ?
