According to an aspect, there is provided a control device. The control device is configured to receive data from a passenger traffic system configured in a building, the data comprising information associated with operations for transferring passengers of the passenger traffic system; based on the received data, monitor a change in a quality of service level of the passenger traffic system in transferring the passengers and a change in a passenger traffic pattern in transferring the passengers in the passenger traffic system; and in response to detecting the change in the service level or in the passenger traffic pattern, run one or more simulations of the passenger traffic in the passenger traffic system in the at least one building using the received data in order to trigger at least one operation to change a configuration of the passenger traffic system.

Control device for passenger traffic system

The invention relates to a method for allocating elevator calls in an elevator system () comprising at least one elevator (-), which elevator system () is controlled by an elevator control () comprising a destination call allocation control, wherein passenger IDs are inputted into at least one I/O-device () of the elevator system (), whereafter based on the passenger ID a destination call is issued comprising the floor of the I/O-device () as departure floor and a preset or inputted destination floor as destination floor of the elevator call. According to the invention when a new destination call is issued, it is checked whether or not a destination call is still pending under the same passenger ID, and if a destination call of said person is still pending, either the new call or the pending call is cancelled.

Method for allocating elevator calls and elevator system

A method and an apparatus for computing allocation decisions in an elevator system is provided. Historical passenger batch journey data relating to the elevator system is obtained, wherein each passenger batch journey includes an origin and a destination floor of the journey, the number of passengers of the journey and the time of the journey. Historical passenger traffic statistics are constructed based on the passenger batch journey data, and expected calls are modelled based on the passenger traffic statistics. The modelled expected call is taken into account in computing subsequent allocation decisions in the elevator system.

According to an aspect, there is provided a method for forecasting elevator passenger traffic of an elevator group. The method comprises training a statistical traffic model describing a traffic profile for a specific cycle with historical timestamped origin-destination passenger counts, obtaining timestamped origin-destination passenger counts for a current cycle, generating an elevator passenger traffic forecast based on the trained statistical traffic model and the timestamped origin-destination passenger counts for the current cycle, and outputting the elevator passenger traffic forecast for use by an elevator group control.

Forecasting elevator passenger traffic

A method for the call allocation in an elevator group uses a call allocation unit of an elevator group control. In the call allocation unit, passenger flow data of the elevator group is used to adapt call allocation parameters to improve the performance of the elevator group. The public traffic data is retrieved from at least one public transportation system, and is used to supplement expected passenger flow data for the adaption of call allocation parameters.

A method and a control device for controlling an at least one elevator are described, by which an arriving traffic intensity is detected, the traffic intensity being a number of passengers arriving at the at least one elevator during a traffic intensity determination period, a traffic amount value is determined by comparing the traffic intensity to a maximum building population, wherein the maximum building population is a maximum number of people in a building, and the at least one elevator is controlled based on the determined traffic amount value.

Peak traffic detection according to passenger traffic intensity

An arrangement of counting passengers in an elevator using two separate counting mechanisms is disclosed. The elevator car typically has a curtain of light arranged to the door and a load weighing device arranged to measure the weight of the elevator car. From the information recorded by the curtain of light and the load weighing device, it is possible to count the number of passengers. The reliability of the counting results can be improved by processing the counting results for forming a combined counting result that provides a more reliable counting result when the independent counts deviate from each other.

Passenger counting arrangement

Modern large buildings and public places are equipped with a plurality of elevators, exits and points of interest for fluent movement. The passenger flows in a building or public place can be traced and modelled by using statistics and information regarding current state of the modelled building or public place. The information derived from this model can be used for controlling elevators, escalators and similar in the building more efficiently. The same information may be used also for guiding passengers in the building or public place to use other transportation means so that the duration high traffic situation can be reduced or sometimes completely avoided.

Evacuation controller

A method for allocating an elevator in an elevator system constructs passenger batch size distributions for each pair of floors in a building based on passenger batch journeys, each passenger batch journey defining at least the origin and destination floor of the journey, the number of passengers relating to the journey and the time of the journey; receives a call for an elevator; estimates the number of passengers waiting behind the call based on the passenger batch size distributions; and allocates the call to an elevator being able to serve the estimated number of passengers.

Passenger number based call allocation in an elevator system

A method for controlling an elevator where an elevator is allocated for the use of a passenger in a first optimization phase in such a way that a first cost function is minimized, a second optimization phase is performed, in which the route of the allocated elevator is optimized in such a way that a second cost function is minimized.

Method for controlling an elevator system

Radio signals are communicated on spatially separate radio paths across a doorway of an elevator. Signal strengths of the radio signals are measured and used to determine traffic served by the elevator. In this way traffic boarding and leaving the elevator may be measured when more than one unit of traffic, for example people, pass through the doorway simultaneously.

Monitoring traffic units served by elevator via radio signals transmitted across doorway of an elevator

Method for handling erroneous calls in an elevator system, which includes at least one elevator, call-giving devices for registering calls on the floor levels and/or in the elevator car, and also a control system that responds to the aforementioned calls. One or more calls given by a passenger are registered, it is assessed on the basis of at least one criterion whether some call is erroneous, and at least one corrective action is performed for removing a call, or for rectifying the call data of a call, if the call is ascertained to be erroneous on the basis of the aforementioned criterion.
