Rader Assistant Examiner-W. E. Duncanson, Jr. Att0meysA. T. Stratton and C. L' Freedman ABSTRACT: The floors of a structure having multiple elevator cars are divided into a plurality of zones. When a demand for service is registered from a floor, an available car is assigned to the zone of the demand for the purpose of answering the demand. A car making its last stop in the up direction may become available even though an up floor call is registered in a higher zone. For a down-traveling car a detector responsive to presence of a passenger may prevent selection of the car as available. Registration of a floor call for a predetermined variable time makes it a priority call. A car is selected for basement service in a predetermined order of preference. Under certain conditions, if no car is at or assigned to a certain floor a car may be assigned to such floor. Under emergency conditions each available car may be assigned successively to certain calls.
