I think relation street applies to all the way segments of the whole street
with the same name (if in the same municipality), but I didn't check to be
honest.

>> Ciao Luca,
>>
>> For an example of a road with many variations in how the tram tracks are
>> embedded, you can have a look at this stretch I mapped a few months ago:
>>
>> http://www.openstreetmap.org/#map=16/50.8601/4.3117
>>
>> To indicate how they belong together, maybe a street or associatedStreet
>> relation makes sense?

>>>
>>> I searched the wiki for a tagging or relation scheme, but found none.

>>> I was thinking about a simple tagging scheme: tram=yes|forward|backward

>>> For the center way (road):
>>>
>>> tram=yes (it's on both directions)
>>>
>>> and on the two railways:
>>> road=yes (the track lies on a road used by motor vehicles)
>>>
>>> We could also user a lanes modifier:
>>> lanes=3
>>> lanes:backward=2
>>> tram:lanes:backward=yes|no
>>> tram:forward=yes
>>>
>>> The tram tag should not be used for tracks which run separated from the

>>>
>>> The tram tag should go along with access tags, as we have lanes reserved
>>> for trams and buses/taxis:
>>>
>>> http://wiki.openstreetmap.org/wiki/File:Tram_xxii_marzo.jpg
>>>
>>> So the center way (carriageway reserved to psv with two tram tracks in

>>> access=no
>>> bus=yes
>>> taxi=yes
>>> tram=yes
>>>
>>> We could also think about a relation, type=tram_on_road, it could be

>>>
>>> https://www.openstreetmap.org/#map=19/45.49833/9.19607
>>>
>>> but would also be more difficult for users to mantain and for clients to
>>> consume.
>>>
>>> Any suggestions / impressions?

>>> Thanks!
