Destination dispatch is an optimization technique used for multi-elevator installations, which groups passengers for the same destinations into the same elevators, thereby reducing waiting and travel times when compared to a traditional system where all passenger wishing to ascend or descend enter the same elevator and then request their destination.
Without traditional hall call buttons outside the elevators, passengers request travel to a particular floor using a keypad, touch screen or proximity card room-key prior in the lobby and are immediately directed to an appropriate elevator car.
In systems applying destination dispatch, passengers register their destination at an input device at the elevator landing. When the allocated car arrives, it knows where the passenger is going, and thus there is no need for the passenger to register a car call. Proponents of destination dispatch often make dramatic claims about the system's performance. In this way, travel time is reduced as the elevator makes fewer stops for individual passengers, and the computer distributes adjacent stops to different cars in the bank. Although travel time is reduced passenger waiting times may be longer as they will not necessarily be allocated the next car to depart. During the down peak period, the benefit of destination control will be limited as passengers have a common destination.
Inside the elevator there are no floor buttons to push, the buttons are in the locked panel, or the buttons are there but they cannot be pushed except door open, door close and alarm buttons (door open and alarm buttons are mandatory installed in the elevators). They only indicate stopping floors. However, the buttons can be pushed if the destination dispatch control panel is only in some specified floors instead of all floors, like destination dispatch elevators with Hybrid Configuration.
Destination dispatch elevator are divided into two configuration systems:
In hybrid configuration system, the destination hall panels are installed only on the busiest floors (mainly the ground or lobby floor) or certain floors, while the other floors have conventional up and down call buttons. Floor buttons exist and are operational inside the car. This is particulary beneficial to improve traffic flow leaving from the busiest floors. Also, it is especially useful in buildings with heavy up peak traffic. Handicap mode is usually not supported in this configuration (except on the main floor when using the keypad). Some elevator brands that use this configuration are Mitsubishi (DOAS) (discontinued), Otis (Compass), and Kone (Polaris). One example of this system is in the PricewaterhouseCooper Place, in Vancouver B.C., Canada, in which a ThyssenKrupp Destination Dispatch System is only installed on the Lobby floor, and all the intermediate floors have Dewhurst up/down call stations and conventional COP inside the elevator.
In the full configuration system, destination hall panels are installed on all floors. Elevator cars receive destination information from all floors to provide the best service as more complex traffic patterns emerge throughout the day. In addition, there are no floor buttons within the cars - only door open and close, and emergency buttons (alarm button, intercom button, or both). Handicap mode is fully supported in this configuration, to offer an elevator which have floor announcement and extend the door opening time. Most elevator manufacturers feature this type of configuration.
The idea of destination control was originally conceived by Leo Port from Sydney in 1961, but at that time elevator controllers were implemented in mechanical relays and were unable to optimise the performance of destination control allocations.
Mitsubishi Electric introduced its own system in 2002, called the Destination Oriented Prediction System (or further Destination Oriented Allocation System, DOAS-S). This system is powered using ΣAI-2200 artificially intelligent control.
Benefit, detriments, limitation and solution
- Improve accessibility, as a mobility-impaired passenger can move to his or her designated car in advance.
- Reduce waiting and time travel, as the elevator cars skips unnecessary floor stops.
- Improve elevator efficiency and performance.
- It can organize elevator lobbies with orderly traffic flow.
One detriment of destination dispatch elevator is that some people who are not used to destination dispatch elevators may not understand how to use it, even though building managements have put instruction signs how to operate the system in elevator lobbies. Few buildings even have downgraded their destination dispatch elevators to conventional ones with push buttons inside because of too many people complaining that the system was confusing for them or they didn't understand on how to operate it.
One limitation of destination dispatch elevator is that the performance enhancements cannot be generalized as the benefits and limitations of the system are dependent on many factors. One problem is that the system is subject to gaming. Sometimes, one person enters the destination for a large group of people going to the same floor. The dispatching algorithm is usually unable to completely cater for the variation, and latecomers may find the elevator they are assigned to is already full. Also, occasionally, one person may press the floor multiple times. This is common with up/down buttons when people believe this to be an effective way to hurry elevators. However, this will make the computer think multiple people are waiting and will allocate an empty car to serve this one person.
To prevent this problem, in one implementation of destination control, every user gets an RFID card to identify himself (like Schindler ID and later Schindler PORT) so the system knows every user call and can cancel the first call if the passenger decides to travel to another destination to prevent empty calls. The newest invention knows even where people are located and how many on which floor because of their identification, either for the purposes of evacuating the building or for security reasons.

- Destination dispatch elevator system can also be implemented on machine room less elevators, normally for low to mid-rise installations.
- In ThyssenKrupp TWIN elevator system, destination dispatch is implemented on this elevator system as a standard control feature.
- Currently, none of those destination dispatch meet the Hong Kong's "Design Manual - Barrier Free Access 2008 (BFA 2008)" standard which revised in September, 2015, which additionally explained for the requirement of destination dispatch.
