   Does exit direction refer to the compass direction of the 
intersecting road, or the signed direction, and if so which road in the 
list?

   Sign:  I77 North; US 44 East; NC 56 East; Charlotte; Rock Hill; York

[ I made that up, but I remember such exit signs ]

   So someone has to parse the sign to be able to properly enter the 
information?   And I'm still not clear on the benefit of having it 
separated if the first thing the data consumer does is string it back 
together.
