Elevator downpeak sectoring
 During downpeak time period of an elevator system, cars are assigned to sectors of an approximately equal number of floors with remaining floors being assigned to sectors near the lobby, one car per sector. The invention provides a dispatching strategy for serving elevator traffic in both up and down directions, giving priority service to the down traveling traffic while providing limited service to the up traveling traffic. All floors requiring down service are given equal access to the system regardless of the position of the floor in the building.
