Hi!
Please note:
A roundabout is tagged with junction=roundabout.
I've fixed this error here and on
way/304703365

Hi!
Please review highway=rail on
way/222217353
This bridge has a lot of tags that differ from the
connected rails

Hi!
Please review typo highway=private
on way/479199149
It looks like a highway=residential,
maybe with access=destination?

Hi!
Please review typo highway=private
on way/497693624
and
way/497693619

Please review typo highway=private

Hi!
Please review typo highway=private on
way/482719008
I've also noted some ways with highway=service + access=private + living_street=yes
Did you mean access=destination ?

Hi!
You have mapped a few highway=private here. This is not widely used. I assume you meant highway=service + service=driveway?

Hi!
Please review typo type=destinationsign
on relation relation/183544
When I changed it to destination_sign JOSM complained "too many roles"
I assume one has to create one relation for each sign?

Hi!
I've noticed that you changed parts of BR-277 from trunk to motorway. Maybe you can help. Please see
changeset/41088522

Hi and welcome to OSM!
I've noticed that you sometimes use highway=footpath here.
http://overpass-turbo.eu/s/rjF
Did you mean path or footway?

Hi!
I've found the typo highway=footway
on several ways in this changeset.
Did you mean path or footway?
See http://overpass-turbo.eu/s/rjC

Hi!
Please review typo highway=footpath
on way/484897119
Did you mean path or footway?

Hi!
Please review typo highway=footpath
on all three ways in this changeset.
Did you mean path or footway?

Hi and welcome to OSM!
You've used highway=footpath here:
way/519350177
It is an area, so I assume you meant highway=pedestrian?
A normal footway is mapped with highway=footway.

They are still in the database:

Hi!
Nach meinem Verständnis sollte der Weg
way/48560053
mit highway=path + ford=stepping_stones
erfaßt werden.

Found a few more ways with this tag created by you. Some look like residential roads, others like hw=track.
If you also don't know they should be hw=road

Hi!
Please review highway=undefined
on way/510068045
Did you mean unclassified?

Hi!
Please check again the footways in the middle of the roundabout.
Two problems:
1) The ways are not connected to the rest of the road network
2) They probably should be highway=footway

Hi!
Please check highway=motorway_junction
on way way/467914341
The tag is normally only used on nodes.
Why did you add it here?
