ABSTRACT:
An elevator system contains a group of elevator cars. A group controller contains signal processing means for controlling the dispatching of the cars from a main floor or lobby in relation to different group parameters. During up-peak conditions, each car is dispatched from the main floor to an individual plurality of contiguous floors, defining a "sector". Sectors are contiguous. The number of sectors may be less than the number of cars. Floors that constitute a sector assigned exclusively to a car are displayed on an indicator at the lobby. Sectors and cars are selected for assignment in a cyclical or round-robin sequence. If the next car selected is not available for assignment, another car is selected. If no car calls are made to the floors in the sector that is assigned to a car, the next sector is selected. The floors in the sector assigned to a car are displaced to direct passengers to the car. If car calls to the floors are not made, the car doors are closed and a new sector is assigned to the car according to the sequence.
