OK, I've deleted the way. What about adding the tags to the shared node ?

OK. The 2nd one is not yet fixed.

Hi!
You added highway=traffc_signals to a way with railway=tram here. I assume you wanted to change only one node of this way?
way/390457206

Hi!
You created a very short way here with tagging that normally is used for a node. Was that intended?

Same here:way/492247885

Hi!
Please check highway=traffic_signals on
way/493464726
Did you mean track ?

Hi!
Please check your changes on way/284938446
I think you didn't want to add highway=traffic_signals to a building?

Yes, if you want to map the area maybe use area:highway , see
osm.wiki/Proposed_features/area:highway

Hi!
Please review highway=traffic_signals
here:way/516005124
I assume you meant highway=footway and maybe crossing=traffic_signals?
Please check also why the footways are not connected with the major roads. Are there bridges / tunnels?

Same here:
way/495272335
But that doesn't look like a hw=track.

Hi!
Please check highway=traffic_signals on way/496660269
Did you mean track?

Hi!
Please check typo highway=traffic_signals on way/457320394.

Hi!
Please review typo highway=traffic_signals on two ways. I assume you meant track instead, but these roads don't look like tracks, more like disused:highway=residential

Hi!
Please review highway=traffic_signals on way way/472456429
I guess you meant track ?

Hi!
Please check:
What does highway=traffic_signals mean on a parking?
way/42924723

Moin!
Was bedeutet highway=track33 an diesem Weg :
way/542477188 ?
Ich habe kürzlich auch schon einen highway=service33 gefunden und auf service geändert : changeset/54021055
Erst jetzt habe ich gesehen, dass Du gar nicht JOSM verwendest. Wie kommt es also zu dem Suffix 33 ?

Hi!
Please check: What does highway=sere mean ? I it only used here. I guess it is a typo for service?

Hi!
The combination highway=motorway_junction + area=yes is only used here. What was wrong with the old tagging?

Hi!
I've changed the unusual highway=ford here:changeset/54043742
See also ford=*

Hi Robert, sounds great. From sat images one may get the impression that there is no real road network, means, everybody seems to walk the shortest possible way avoiding buildings and other obstacles ;-)
