looks like 1 lane to me but the example would not work for other reasons.

We could do 

  # this is "default" for routers/apps which don't undrestand/use conditional
  # restrictions
lanes:forward:conditional=2 @ (09:00-17:00)
lanes:backward:conditional=2 @ (17:01-8:59)
  # the version for apps which do understand them

However, I am afraid that "lanes=0" won't stop most routers sending cars that 
way, other kind of restriction is needed here.

That could be
access=yes @ (09:00-17:00); yes @ (17:01-8:59)
 # this two lines are needed to sort out routers/apps which don't 
 # undrestand/use conditional
oneway:conditional= yes  @ (09:00-17:00); -1 @ (17:01-8:59)

In principle 
oneway:conditional= yes  @ (09:00-17:00); -1 @ (17:01-8:59)

would be a much more elegant solution but again, I am afraid that 
oneway=reversible isnt widespread enough to be known by most routers.

I have just added that as hypothetical example to

The lane number could be added on top of that  - and would be very
confusing if it were variable because there would be backward/forward
lanes on top of reversible oneway..
