Abstract
Abstract In an elevator system a predetermined number of priority down floor calls prevents an elevator from answering an up floor call for a floor above the highest floor for which a car call is registered in the elevator. If a first car assigned to a floor call is traveling up through an express zone when a second car becomes available in a more advantageous position the assignment is transfered to the latter car. A car may be parked at a floor above the express zone. Scanning for an available car for a call above an express zone starts in a high zone.
