okay, I think I understand now. The idea
was to show that those traffic signals were
controlled by one logic/computer/whatever.
Do you think that the mass edit which changed them all to highway=traffic_signals
should be reverted or should I simply remove those ways?
I stumbled over them because a lot turned out to be highway=track, probably
an auto-completion problem in JOSM.

please review:
way/39080865 has the tag
highway=unmarked_route
which is rarely used.
Does it mean something like
highway=path,trail_visibility=no ?

please review:
what is a highway=traffic_signals ?

please review:
way/316911377 is tagged
highway=traffic_signals
I guess this is a highway=footway,
footway=crossing controlled by a
traffic_signal?

please help me to understand:
why do you connect nodes with
highway=traffic_signals as with
way/296332286 ?
You used amenity=traffic_signals,
now (after a mass edit) they are all
highway=traffic_signals, which looks
completely nonsense.

please review:
way/344476914 is surounded
with nodes with highway=traffic_signals.
They are not connected to any highway.

Bitte prüfen:
seltsame tags an way/222846242:
sieht aus wie eine Verkehrsinsel, hat aber
highway=traffic_signals
und andere tags, die sich eher auf Fußgängerüberweg beziehen.

yes, a used motocross trail looks very different.
Seems you also don't know what it is (now)?

please review way/159480352:
what does highway=traffic_signals mean?
Is this some kind of ring and the signals are mounted on it?

please review: way/130845148
was changed from highway=footway to
highway=traffic_signals !??
Bing seems to show a small bridge here?

okay, done

okay, I thought it is used for motocros
In fact I try to repair typos in highway tags,
I am not so much concerned about rendering.

please review way/353684336:
would it be okay to change highway=racetrack to highway=raceway so that it is rendered in the map?

hmm, I don't see any gps tracks in JOSM.
I am not a local, can't say more.

please review:
way/319479338 has the tag
highway=obsoloete
What do you try to say with this?
Is it an existing way that will be destroyed soon? Or is it obsolete in OSM because there is no way?

please review:
way/69727080 has tag
highway=nothing_there
note=destroyed by harvester
Is that still true? If yes, is the relation
still up to date? Shouldn't the way
be tagged highway=dismantled ?
