Because most buildings now they just put one button so people stop clicking both
What? I’ve never seen that. The elevator needs to know which way you want to go.
I am currently staying in an AirBnB of a 60 floor tower, and the three elevator shafts definitely cannot handle this (I don't think the building was designed with renting to tourists in mind). The elevators are frequently completely saturated during weekends, meaning that the elevator stops at each floor, but noone can get in because the elevator is already full. This means the backlog of people wanting to use the el…
> 60 floor tower, and the three elevator shafts I don't think I've ever seen a 20-story building with less than 4 elevators at a minimum. I've worked in low-rise office buildings with no less than 10 elevators. Seems like that gross deficiency should have been stopped at the city inspector's office before plans were approved.
My biggest issue with elevators is that some places and hotels I‘ve been to use disconnected systems: They have three elevators, but pressing one button only calls that specific elevator. So everyone presses all three buttons, meaning the three elevators basically turn into one. I don‘t understand how this was ever signed off, but I‘ve seen it multiple times now...
In general my understanding is that every single cab is unit that can operate alone separate from any others. Then these are grouped together to operate more efficiently. But this is feature you need to buy. Going too cheap someone might choose not to.

The data is already there. This also gets more interesting when you expand the scope from just elevators to general building occupancy and movement. In the simplest sense, I've seen this tied into security gates so as people badge on when entering the building there's already suitable elevator movement to meet demand by time the foot traffic reaches the lift lobby. That can then also feed into destination dispatch if…
> (...) and a lot of very good things from a sustainability and general optimisation perspective. The flip side is it also has the potential to be an absolute dystopian privacy nightmare. Privacy is an illusion for most people, and in office spaces, it's also a red herring. Wifi trilateration doesn't make things worse when you have a CCTV camera on every corner, badge reader at every other door, and presence sensing…
Indeed, the Boimler Effect, amongst other things.
I see an analogy, Food : Malthusian catastrophe :: Money : No room for profit in an economy.
The biggest problem I always have with elevators is not the algorithm, it's the people seemingly being unable to grasp the concept of pressing either the up or the down request button, depending on where they want to go. Almost always I find someone will press both, because "then the elevator comes faster". Completely ignoring the fact that they end up going the wrong way first half the time, and adding an unnecessar…
I live in Ireland. 10+ years ago I used to the travel to the US quite a bit (5-10 trips a year). The majority of the time I would fly via a major EU hub like AMS or CDG even if there was a direct flight from Ireland. The reason? Other factors that were important to me! Examples: - cost optimisation. I could fly business within company budget rules. - flight time. I highly valued longer flight times between Europe and…
Aside for the algorithms and how well they work, there is a psychological aspect to how people perceive "wait" times. It turns out just waiting is very annoying. But having people do anything during that same wait period → perceived as progress → not upset. An example iirc was waiting for luggage at the airport. It takes min of x minutes for the first bags to show. In one version, passengers went directly from the ga…
All I want to know is why the heck I can't un-press a button I pressed by accident. This should be very simple. Press once to turn the button on, press again to turn it off. Or I guess you could do long-press to turn off or something if you're worried about confusing people, but I really don't think that should be necessary. We know how toggles work. The button lights up when it's on.
In some old systems with buttons that actually pushed in and popped out upon arrival, you can pull them out to cancel your call: https://news.ycombinator.com/item?id=37385826 More examples: https://www.youtube.com/watch?v=JzC5Bpz-PkQ https://www.youtube.com/watch?v=xYtsNxzDR50
This man has sixteen hundred videos of riding up and down elevators and is still going strong. Amazing. I love how Grandma was willing to ride random elevators and feature in his videos if it meant she could spend time with her eccentric grand son.
