Are these things used outside of TALES at all?  I don't think so, but 
I'd like to be proved wrong.

If they are used only for TALES, then they should be ITALESTraversers.

I'll invoke "AL" at this point:  "Abstract Later"

(AL is a pal of DON, YAGNI and WHUI.)

Ok, so how about IURLSegmentTraverser and IURLTraverser ?

I really don't like to have to remember or to explain the difference 
between a "traverser" and a "traversable".
