    The worst situation I've encountered is after a large conference when everyone is leaving the hotel at once. An elevator quickly fills up on the way down, but then wastes time stopping at every subsequent floor with a call, even though no one else can fit inside. At each floor the elevator stops, the doors open, the waiting people see it's already packed, the doors close, and this repeats on the next 15 floors before finally reaching the bottom where everyone gets off. If the algorithm could know an elevator is completely full and only stop at its destination floors rather than every floor along the way with a call, it would be far more efficient.

      It would have to be done by weight. If you had a button to not allow stopping for others, people would abuse it. If it was a camera, security issue. Presumably if somebody is moving a piano or something else heavy it'll be fine

        You could also detect when the elevator call button gets pressed again right after the elevator has left a floor. That means someone wasn't able to get on the elevator (and is now waiting for the next one).

        Following rz2k's suggestion, you could have a building employee operate the elevator during busy times.

        What security issue? Many hotel elevators already have cameras.

          Because there would need to be some automated service and you best believe it'll be flock 2.0

            This could easily be done locally with no network

              I mean this in the nicest way possible. Do you see all these cloud photo/video leaks like from robot vacuums or whatever and think they don't know it can be done locally?
