We have similar arrangements here in Cambridge, and elsewhere in the UK. In
Cambridge, instead of a hold in the road, they use a rising bollard which a
transponder on the bus lowers to let it through (In Oxford, they just put a
sign up saying 'buses only' or some such). In Cambridge these bus gates all
have cycle bypasses. In at least one case, the restrictions depend on time
of day (bollards are lowered at other times).

We also have the cycle gaps you mention. Further, we have streets which are
one way for only the few metres at the end, with a cycle gap to allow
cyclists to bypass the no entry (a 'cycle plug').

So far I have represented these as follows (I did them this way so they show
up on the rendering; I noted we already have tags to determine allowed
access permissions for buses (psv) and the like):

Bus gate: three ways linked to two nodes (close together). The ways on the
outside are highway=cycleway and the one on the inside is
highway=unclassified or whatever and access=no psv=yes. To make it clearer I
have sometimes used highway=service to distinguish it from the roads at
either end. Example in the middle of:

(the restriction isn't indicated, of course)

Cycle only gap: just a short length of cycleway between two highways
Examples, between Leys Road and Highworth Avenue at

Cycle plug: a short length of oneway highway continuing the two way road,
with a short length of cycleway parallel.
Example: several along St Philips Road at

them) (photo http://www.camcycle.org.uk/map/location/6357/)
