ABSTRACT:
An elevator system which improves service to floors located below the main floor, i.e., basement and subbasement floors, by treating up and down hall calls originating from these floors as separate up and down basement zones. A hall call is allocated to a suitably conditioned busy car, if such a car can be found, and if the hall call cannot be so allocated, a demand is created for the zone associated with the call. Non-busy cars which are available for assignment are assigned to demands in a predetermined zone priority order, with the up basement zone being higher in this priority order than the down basement zone.
