I would be surprised if people standing still can be higher capacity than
people moving!
I was stating a fact rather than an opinion. How well it works in practise
depends on how efficiently people load themselves onto adjacent steps of the
escalator, so it helps a lot if everyone knows in advance that they will be
standing both sides.

You only have to come off a free moving 60mph road onto a 30mph road to
know the traffic immediately closes up and slows down and queues form.

The optimum speed for maximum road capacity is around 15 mph; stopping
distance (and thus vehicle spacing) is proportional to the square of speed.
Using road capacity more efficiently is largely what the variable speed
limits on the M25 and elsewhere are all about.

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.

To save further argument (which I realise is not the objective of the
group), see

explains everything!

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?

Thanks for the reference.

It mainly explains that there's not an easy answer!

The main result seems to be that walking and standing capacity are
pretty much equal, unless you have very experienced walkers, in which
case it improves for them slightly.

In general the same rule applies as on the motorway. Keep {left,
right}. Use the other lane to overtake if necessary. It's not
usually a problem if everyone moves to the right if and when they can.

I wonder why TfL don't speed up the escalators a bit when the demand is
high? In Russia and other countries of the ex Soviet Union the
escalators clearly run much faster than ours - my guess would be about
50% faster. Metro users seem to cope without difficulty.

The elf n softy bed wetters probably wouldn't allow it. Also given the
lack of reliability of LUs escalators they'd probably end up fixing them
twice as often.

To be fair the stations in Moscow and Kiev are pretty deep. If the escalators
ran at LU speed you'd spend most of your commute standing on them.

It would probably mean upgrading the motors, which is a non-trivial
activity.
