Abstract
An elevator dispatching method which estimates the time of arrival (ETA) of each car at the floor of a hall call to be assigned. A building profile of average door cycle times per floor, over predetermined periods of the day, is tabulated and used in the ETA calculations, to provide more accurate ETA values and thus a lower average call waiting time.
