text: Ok. "additional fictitious bollard to the east of where they actually are". I think that's intended to be representing the same thing as the split up way bits which had more access tagging details. I can actually see in the photo that the positioning reality half way between the two. So I've moved both the split ways bits, and the bollards to be in the same correct place.
  
  I've copied the access tagging from the ways onto the rising bollards too. That fixes the immediate issue which was confusing me, and allows me to get by bus routing working. So I'll set this to "resolved"
  
  However there remains the more fiddly challenge, of adding more complex tagging representing the time-based restrictions. Currently it just says "access=no, bicycle=yes, taxi=yes, psv=yes"  This implies cars never. Not quite right, but maybe a reasonable simplification until someone works out the timing tags
