It is very good UX how escalators slow down when nobodies on them but keep moving.

It makes it clear the direction of movement and how the user has to position themselves so they can ride it without thinking about it- but it saves power from slowing down
I've never noticed this.
not all escalators have this, you'll have to look out for ones in lower-traffic areas.
Makes sense, my town only has 3 sets of escalators that I know of so I don't see many.
I've never seen an escalator change its speed before. Neat.
Wonder if they'd use a current threshold for determining if someone is on the escalator?
I'm actually a retired electrical engineer, used to do aircraft avionics. Anyway it's a simple thing to measure amperage loading on the motor to set a threshold for sleep and wake. But in engineering there's always more than one way to accomplish a task. An optical sensor and timer would be another way to do it.
If you were using a vfd in order to control the speed of the escalator, a lot of vfds have intelligence built in, so you could just wire it up and have the vfd take care of everything. On the other hand, I can see a bunch of reasons why a current might work really well for a short term demo and start to fail immediately after. Start to get things gummed up or also trying to deal with very small people riding the escalator, the trigger point might be difficult to keep straight.
Photoelectric barrier at the entrance for acceleration and a timer to slow it down.
Escalators are more advanced than I'd realized.
So THAT’S what that’s for.
As long as they don't stop. I embarrased myself once because of that
I haven't seen one of those, but I don't get out much. But yeah such a simple feature with so much benefit.
