Interesting. I didn't realize that destination dispatch told the user what elevator to take at the time of request. (I've never used it.) Why not have active display above each elevator that says what floors it is going to when it opens?
Because it doesn’t know that until after it has completed the trip?
Also, I don't think that destination dispatch would work if the elevator didn't commit to going to the users's floor at the point the user got onboard. It may also stop at additional floors that weren't committed to when the user entered, and it may drop floors it was thinking of going to before it picked up the user (if the user onboard isn't going to those floors), but once the user gets onboard, that floor is a hard commitment.
