The flexible destination control system

Ever larger office complexes and public buildings result in increased traffic volumes and pose new challenges for operators and lift manufacturers. Particularly in busy high rises, lift systems are pushed to their limits during peak traffic times. The result: overfilled cars, long wait times and unnerved passengers. Previous approaches for finding a solution concentrated on two aspects in particular: increased car speed and a larger number of group members. These possibilities have their limits as well, however.

  • Improved transport capacity:
    Efficient utilisation of the lifts by grouping together passengers with the same target floors
  • Shorter travel and wait times:
    Through the optimised transport capacity and by taking into account the path between the terminal
    and lifts, both the travel times as well as the wait times can be effectively reduced.
  • Optionally with touch screen or mechanical keyboard
  • Individual touch screen design
  • Bus driven system provides for simple infrastructure.
  • Fast system integration

Offering an ideal solution is the destination controller. Unlike conventional group controllers, the passenger does not specify the desired direction of travel, but the desired target floor. This additional information flows into the group algorithm calculation and allows for a considerably more efficient passenger distribution into the individual lifts of the group, thereby contributing to an effective reduction in empty trips and intermediate stops. The flows of passengers are systematically directed and the system optimally utilised.


With the conventional collective call controller, passengers press the direction button on the landing call panel. A systematic assignment of passengers occurs solely on the basis of the up or down direction. With a ten-storey office building, this means, for example, that in the morning all passengers on the ground floor would like to travel upwards.
Assignment by floor does not occur in this case. As a result, all lifts of the group are in use and inevitably stop on each of the selected floors.


With the destination controller, the passenger specifies his or her desired target floor on the so-called landing call terminals. The car assigned by the controller is displayed on the landing call terminal. The passenger enters the indicated car and travels on it to the target floor. Ideal grouping of the passengers on the respective lifts is ensured, thereby resulting in efficient utilisation of the system and optimised passenger flows. Because the landing call terminals do not necessarily need to be directly at the lifts, they can also be installed in the immediate vicinity of the entrances. On the one hand, this results in a perceived reduction of the wait time at the lifts, since the path between the terminals and lifts can be effectively used to retrieve the car. On the other hand, it opens new possibilities for building architecture.
