I'm sorry? Are you saying that people passing a point, say half way down the
escalator at speed X in 2 columns will carry more than one column at speed X
and the other at 3-4X (which is what walking achieves)?

I doubt that walking down more than doubles the throughout, and against
that you have to balance the increased separation between walkers
compared with standees.

And the walking speed varies quite a lot between individuals, which will
tend to increase the separation.

Also, what about the effect of the queueing for the standing side which
tends to clog up the approach to the escalator and slows down the
would-be walkers?
