both solutions wouldn't solve the problem that a street might have
more than two names

just to repeat my example with "Bundestraße" in Germany or RN in France

Outside of cities, the Street has just a Label "B nr" or "RN nr",
inside, it also has a name

Ex. 2 Names
B26 - Wilhelm-Leuschner-Str. (Griesheim) - Rheinstr. (Darmstadt)

3 Names:
B42 - B42 + B3 - Gräfenhäuser Str. (Darmstadt) - B42 ends here
                                   B3 continues on Kasinostr.


Or for Imi in Munich:

2 names: Landsberger Str = B2
3 names: Brudermühlstr. = E54 and "Mittlerer Ring"
