Abstract
An elevator installation has a vertical elevator hoistway and a plurality of elevator cars individually movable therein. An elevator control system readies at least two of the elevator cars in the hoistway in an area of two mutually adjacent entrance areas. Thus, simultaneous loading/unloading of the elevator cars via the entrance areas is possible. The two elevator cars then travel to destination floors, the first elevator car traveling a distance which is at least as great as that traveled by the second elevator car.
