It would be easier only if hopping up and down didn't entail a

OK, imagine it another way:
You take the normal flatland car traffic, with 'x' number of cars,
and split it up
over 'n' levels vertically. None of the cars switch levels in the
usual course of
movement (except when taking off or landing, for which you have special
collision avoidance logic - they do it one level at a time, etc.).
So now you have x/n cars on each level, rather than x cars on a
single level,
greatly reducing the chances of collision on any level (even without
automatic
collision avoidance systems). Additionally, your virtual "roads" on
each of these
levels can be arbitrarily wide, to further reduce the risk of collision.
