Abstract

The estimation of the amount of time required by a given elevator to reach a given hall call, known as remaining response time (RRT), can be improved by using not only the present car position, its direction, and the number of intervening stops for already boarded passengers, but also the destination of each waiting passenger. An elevator controller is shown with an algorithm for estimating RRT using such detailed destination information.
