Sorry, one (& hopefully last!) thing occurred to me over the weekend: some turn restrictions have exceptions for buses, bicycles, etc. TriMet's uses for OSMSplit will include bus operations, so these turn restrictions should not be included. We could deal with this in a couple of different ways-- 1) just having an extra column in the turn restrictions & prohibited turns tables that indicates when there is a bus exception (so we could filter them out on our end), or 2) just not including them in the first place.

Example turn restriction of this type:

5th & West Burnside in downtown Portland - http://www.openstreetmap.org/browse/relation/1694125
