As far as pedestrian navigation is concerned, it depends on whether
sidewalks are mapped as separate ways or as tags on the road. In the
latter case, a pedestrian router doesn't know that there are tram
tracks on the road, but that there are tram tracks *next to* (outside)
the road.

Consider the following crossing and imagine that the northern sidewalk
of Schlossstrasse wasn't mapped as a separate way, but as sidewalk=*
on the road way:

When turning from the northern sidewalk of Schlossstrasse into
Mutacherstrasse, a pedestrian router would assume that one has to
cross tram tracks (which obviously isn't the case). Even for vehicles
driving on westwards on Schlossstrasse and turning into
Mutacherstrasse a router would assume that the vehicle has to cross
tram tracks (although in reality the tram tracks are located in the
middle of the road and the traffic lane further away).
