Abstract
A wait time prediction apparatus for an elevator which takes into consideration the difficulty in measuring actual waiting times of individual users for the group supervision of the elevator and provides apparatus to record the registration time of each call and the number of getting-on persons corresponding to the call, to accumulate such records so as to provide a function defining the average number of passengers getting on the elevator corresponding to each call registration time, and to integrate the function with respect to the call registration times for a predetermined period of time and to use the result as a predictive summation of the actual waiting times of the individual passengers getting on an elevator which serves a call after a predetermined time from the registration of the call, which cannot be directly measured.
