A 'one in a million' ride, simple,
one in seven trillion - that`s a bit more complicated.

System Operation

When a request for service is made to even a comparatively small elevator group of, say 4 elevators serving 15 floors, there are over 7 trillion possible ways of serving that call while fully considering all the other calls currently in the system. In order to find the best one we need to consider them all, and do it in a fraction of a second so we can respond to the user. A seemingly impossible task which is why no-one has ever attempted it.

Except Schindler

We found the secret 10 years ago and have been refining it ever since.
It’s reached a whole new level in The PORT Technology.

  • The PORT Technology is how Schindler does Traffic Management.
  • The PORT Technology has the most advanced elevator control ever conceived.
  • The PORT Technology will find the 1 in 7 trillion ride that's right for each user.

Just to put this in perspective, it’s like finding one star out of 27 galaxies, every time a call is put into the system. Tough mathematics indeed and producing it has taken Schindler over 30 years of research effort. But it’s worth it because every passenger using a PORT-based system knows that the ride they are having is the very best that can be provided by the elevators available in the prevailing traffic. And that means that at all times you can be assured that your elevator system is running at its pinnacle of performance.

With The PORT Technology you not only get this extraordinary capability but a host of other features to allow your building to operate using Transit Management and therefore maximise its potential.

Among the standard features included in The PORT Technology and a number of advanced options to further tailor the system to your needs.

Redefining, yet again, the pinnacle of performance that a specific group of elevators can reach.

20 years ago, Schindler pioneered destination dispatching, generally acknowledged to be the most efficient stand-alone method of moving passengers vertically through a building. It was this unparalleled experience that allowed the development of the PORT Technology’s vertical transportation component that, even when considered in isolation, is another major step forward in traffic management.

Destination control – what is it and how did it start?

The PORT barrier

PORT Technology was designed to bring a new dimension to the use of barriers in the building entry process. With PORT, not only can each entrant be verified as valid but an elevator for their preferred destination floor can be ordered and its identity communicated, right at the barrier. And, because this is a PORT control, we can guarantee that the elevator will provide the best possible journey in the prevailing traffic conditions.

We recognised that a PORT barrier would bring major benefits to our customers. What we did not want to do, however, was to insist that these benefits were only obtainable if a specific make of barrier were used in its implementation. Which is why we say that “the barrier can be whatever you want it to be”. Choose the manufacturer who provides the aesthetic and operation that you are looking for in your building and a simple PORT interface will do the rest. Mechanically PORTs can either be fully integrated into the body of the barrier or make an attractive addition to the top surface. Electrically, a simple standardised three-wire interface can be quickly connected. The end result is exactly the barrier you wanted with the expanded functionality that you are used to with PORT Technology.

RFID Entry

Each PORT is equipped with a reader which can communicate with any compatible Radio Frequency device ranging from a simple card to a smart phone. This can be used to provide special features during normal elevator operation or, when the PORT is incorporated into a barrier, to provide an access control system which is fully integrated with the elevators.

Forward Credentialing

This optional feature is to discourage passengers from entering into a cabin, for example with a colleague, without using their badge. If a passenger boards an elevator without using their badge, a sanction is applied when this badge is used again. This may range from a warning message on the PORT screen to a requirement to reset the badge at the security desk in the lobby.


When the PORT is used in conjunction with a barrier, this feature prevents a user passing their card back across the barrier to facilitate entry of another person by invalidating the second transaction at this barrier or any others nearby.

Predictive Parking

Parking can be configured such that the system uses real-time statistical data to determine the most likely demand floors during the current time period and parks the elevators accordingly. Alternatively the customer can pre-define parking floors.

Long Waits Reduction

The PORT Technology cares about each passenger’s waiting time and efficiently minimized the probability of longer waiting times without compromising average waiting times or overall handling capacity.

Special features
for special journeys.


In many tall buildings it is desirable to maximize elevator hoistway usage by deploying double-deck elevators. With conventional systems these can prove very frustrating for the user as, for example, a lower-deck cabin stops repeatedly because of a service requirement at the upper-deck or there is confusion as to what cab must be entered at a lobby. With The PORT Technology this issue is virtually removed. Since we know all the passengers and their destinations in advance the double-deck elevators do not stop more often than single deck elevators. In addition the advanced signalization provided by the PORT screen eliminates any passenger confusion.

Shuttle Control

A shuttle service between 2 floors can appear to be the simplest of elevator operations. In fact if it is not optimized there is potential to transport far fewer people that theoretical capacity and cause long waiting times. The PORT Technology Shuttle control uses passenger volume assessment tools to set up an advanced service pattern that at all times maximizes the flow through the system while minimizing wait times.

Crowd Prevention

In a sky lobby environment where passengers are being delivered to the area by elevators from the main lobby and then re-boarded into elevators to higher floors there is always a concern that overcrowding may occur. By comparing the number of people delivered to the sky lobby with the number leaving the system can detect this possibility and retard the delivery volume until space has been created.

Everyone’s been talking about evacuation using elevators, only
The PORT Technology has a credible scheme to help make it happen.

Emergency Evacuation

Since The PORT Technology knows who has been delivered to each floor it can build up a picture of the population distribution at each floor. In the event of the need to evacuate the system can decide which floors can be evacuated via the stairwells without overcrowding and advise those occupants to take them using its screen. At other floors it can offer an elevator evacuation and, since it knows the population, can bring enough elevators to take everyone on a specific floor at once thus avoiding panic.

An unavailable elevator should not mean unavailable good service.

Peak Performance Booster

In normal circumstances the elevator configuration is designed to provide excellent service to its occupants. There may be times, however, due to an unusual influx of visitors or large-scale loss of elevator cabs (for example due to construction) when this is no longer the case. Using the advance communications capability of The PORT Technology passengers can be instructed to either walk down 1 flight of stairs to pick up their elevator or be delivered 1 flight above their destination. This would be undertaken to combine required stops and therefore, by making elevators more rapidly available, to significantly increase the handling capacity of the units.

Energy Control Option (ECO mode)

During low traffic periods, a typical elevator system, in an attempt to minimize waiting times, will assign individuals their own cab. Since an elevator is counterbalanced at half load, this results in many trips with highly unbalanced loads and consequently high energy consumption. In ECO mode “low traffic” trips are planned to allow for reasonable rather than minimal waiting times. This means that all elevators are not needed thereby providing significant energy savings which are increased by biasing the number of passengers per car to be as close to the balanced load as possible.
