[Tagging] Tram tracks running in a road

As I said before, it's simply a model. We have always drawn 1 way for each
stretch of asphalt. We also draw 1 way per track. They sometimes overlap,
but it turns out that this doesn't happen all that often.

Maybe this is the reason why they decided to draw rails instead of tracks
in the UrbIS dataset. But that's a different model. Probably makes more
sense in a GIS system.
