Or maybe it is an amenity=parking?

.. at least in the northern part ;-)
Maybe you also know what this is?
way/335875843

Hi!
Please review position of this highway=secondary:
way/336091538
Current Bing shows a road next to this roughly drawn way.

I've changed it back to path:
changeset/52919376

Ach ja, weißt Du evtl. was dies hier ist?
way/131730185
Evtl. road_marking=dash?

Bitte mal prüfen:
Es gibt zwei Relationen name=Travemünder Landstraße, ich denke diese kann gelöscht werden:
relation/1793028
Allerdings sind nicht alle Member davon in relation/1658339

Esri sat image now shows a turning loop next to an amenity=parking

I don't know the road and cannot see it on sat images, so I really don't know for sure. I assume hw=residential may also fit, esp. when you have a name as well.

Hi!
Please review highway="residential et éclairée"
Did you mean highway=residential + lit=yes?

Hi!
I've corrected the unusual highway=parking_aisle
to highway=service. I did not add service=parking_aisle because I don't think that this is their main purpose.
changeset/52916811
See also service=parking_aisle

Hi!
Please review the rarely used highway=access on way/532407488
I assume you meant hw=service?

Hi!
Please review highway=5 on way/389925791
Maybe you meant addr:housenumber=5?

Hi and welcome to OSM!
I know it is a bit late but I've noticed this changeset because you added a lot of points with tags that are not useful for OSM.
I've removed the data here:
changeset/52880719
Please let me know if you think that the data is useful for OSM and I will help to make it useful.

I've reverted most of this changeset here
changeset/52880303

Hi!
I've noticed that you added crossing=zebra
to ways with highway=crossing.
The way is a footway and should have the tags highway=footway + footway=crossing
and maybe crossing_ref=zebra were appropriate. The node that is shared by the footway and the major road should have the tags highway=crossing and and maybe crossing_ref=zebra.
See also highway=crossing

Hi!
Please review the ways near
way/532057738
The tag highway=crossing is only for nodes, the way way/532057737 has no tags.

I did not dare to remove the areas. The maxspeed tags are on the normal highway ways and not needed for areas.
If you like, please delete the areas.
I think they were created as an experiment.

Hi!
Please review way/474617988 and
way/474617989
Are you sure that these are not roads?
Or are there roads parallel to the drains?

Hi!
Please don't use highway=* for elements of a playground like
way/531616462
Please check playground=*
for common tags.

Hi!
This looks like an import to me. Unfortunately the data is not useful for OSM because you did not tag the nodes or connect them with ways. What was the source for these nodes? Did you follow osm.wiki/Import/Guidelines ?
