Yes that was the point. But although it might seem to be the right
thing to do in theory it seems that it doesn't actually work in
practice.

There is a little more on this in Ian Visits blog:

No more really, since it is mostly the 2002 paper that has already been
mentioned more than once in this thread (which doesn't actually prove
anything in my opinion).

I think what it proves is that it would be really hard to implement
such a
policy in the few cases where it would be worthwhile: long up
escalators in
the peaks. In all other cases, it's better to have a walking side and a
standing side.

Given that many London Tube users aren't fluent in English, most regular
Tube users are well-trained to walk on the left and stand on the
right, and
many aren't listening to routine announcements, it would be nigh on
impossible to switch behaviours on a few escalators for a couple of hours
each day.


Make the steps a metre high and two metres long.

.... that will make them wheelchair accessible too.

Well that would be believable - if I hadn't seem it done (at a very
crowded Victoria some years ago with a couple of staff yelling - sorry,
giving instructions - at the bottom of the escalator).

The thing about asking people not to walk on the left if that you only
need a few people to obey.

I had a look at an escalator on Monday towards the end of the rush hour
and most of the people on the "standing" side walked up the 'last' three
or four steps. So it's not a completely binary situation. As it was a
short one, people were roughly equally using both sides. Today I looked
at a few longer ones, albeit not in the rush hour, and almost everyone
was standing [on the right], and very few walking [on the left].

I think this was the reason given for trying it first at Holborn as it
has rather long escalators, but surely not the longest (Angel?).

I've only used Angel station a couple of times but I don't remember it
being particularly busy, so maybe they didn't try it there because
there's no problem to solve there.

You may now start misinterpreting what I just

Angel station is very busy in the rush hours, but it isn't an all-day
tourist/shopping destination.

Holborn is busy for much longer, and has a congestion problem that needs
solving.

The easy solution, in my opinion, is simply to run the escalators a bit
faster, say a 25% increase in speed at rush-hours. Most users then are
commuters so will easily cope. Those in Russia and nearby countries
seem to cope with much higher speeds.

I just returned from my most recent trip to Beijing which included several
subway journeys. If you want to experience crowding, that's definitely the place
to see it. It's not just the cars that are full, but the platforms and halls as
well.

What seems to happen on the escalators when things are crowded is that no
walking up occurs - standing both sides. They don't run them above average speed
though.
