text: I don’t know how to mark this so that when planning a route it DOESN’T try to take any vehicles other than buses down Binfield road from Clapham Road. That means no left turn heading north and no right turn heading south as well as no through road heading west.
  Any help with this notation (I’d rather it be more than just an annotation and actually affected the routing algorithm which would help everyone who uses these maps), would be most appreciated.
