Elevator Traffic Simulation Procedure
Passenger service level in an elevator system depends on the group control and cannot be calculated directly. With conventional control, waiting times and interval have a correlation in up-peak. With a destination control system (DC), interval and waiting times...

New trends in elevatoring solutions for medium to medium-high buildings to improve flexibility
Medium to medium-high buildings with heights between 20 to 40 floors have traditionally been built using a minimum of two elevator zones, low-rise zone and a high-rise zone. Passenger transfer between...

Passenger behaviour in elevator simulation
Elevators should be an integral part of a building transportation system. However, the integration of several transports and their ability to handle different kinds of passengers can usually be verified only in practice. Elevator planning typically assumes passengers with standard characteristics...

Double-deck destination control system
Double-deck elevators are used in tall buildings to reduce the core space occupied by elevators. The handling capacity with double-deck elevators is approximately 1.5 times the handling capacity of single-deck elevators when considering different traffic patterns. In an up-peak situation...

Elevator selection with destination control system
Elevator planning is based on up-peak and calculation of handling capacity to meet the building traffic flow demand. With a collective control system based on up and down call buttons, up-peak is the most demanding traffic situation considering...

Optimal control of double deck elevator group using genetic algorithm
We shall introduce the principles of optimal routing of double-deck elevators. Elevator routing problem is formulated as an integer programming problem and it is solved using a genetic algorithm in a real time system. The optimal...

Traffic planning methodology
Measurements in office buildings show that passenger traffic intensity is often highest during the lunch hour period. Up-peak boosters are used to increase handling capacity during heavy incoming traffic. Boosters decrease round trip time...

Understanding the natural behaviour of elevator safety gears and their triggering
A logically operating safety gear can all of a sudden function completely erratic. This article explains the behaviour of friction, the effect of friction tolerances, why erratic behaviour occurs and what can be done...

The advantage of PMSM technology in high-rise buildings
In 1995 KONE introduced PMSM technology in the low rise volume market with its revolutionary MonoSpace®. The small EcoDisc® machine allowed the complete elimination of the machine room, as it fitted in the hoistway. Gearless...

Energy-efficient elevators for tall buildings
According to elevator traffic studies, the traffic patterns in an office building, such as number of starts, round trips, and number of transported passengers, are repeated quite the same from day to day. In this study, the energy consumption of elevators in tall office buildings is studied by...

Efficient evacuation methods in tall buildings
The speed with which people can be rescued from a building can be crucial in saving lives in many emergency situations. In this article, evacuation studies have been made for an ideal situation where no smoke effects, or fire, and no damage to the building...

Advances in elevator technology: Sustainable and energy implications
Elevator technology has seen dramatic changes the last couple of years. One of the most remarkable changes has been on the control algorithms side. The Introduction of the Intelligent Hall Call Destination Dispatching system has increased elevator efficiency tremendously, and has allowed a 20-25% reduction in the number of elevators required. Intelligent Hall Call Destination Dispatching has now also been introduced on Double Deck applications. A 52 storey office building...

Transportation design for building evacuation
Evacuation is currently based on using stairs in most tall buildings. In planning stairs, the height of the building is not considered. This leads to long evacuation times in high-rise and mega high-rise buildings. The planning of elevators in most tall buildings such as offices, hotels and
apartment...

Evacuation mode for total building evacuation
The logic of a total evacuation mode of an elevator system includes user interfaces and system interface requirements during an emergency situation. High-level requirements for conventional group control and destination control
systems are also significant issues...

People flow and automated transportation
with hospital elevators
Hospitals are one of the most complex environments for which to plan vertical transportation for fluent traffic handling. There are several needs for transportation: people, beds with nurses, and goods. In principle, separate elevators should be reserved for...

Passenger traffic flow simulation in tall
buildings
Elevator traffic can be calculated analytically for only up-peak situations where passengers arrive at the entrance floor and travel to the upper floors. In other
traffic situa-tions, such as outgoing, two-way or mixed lunch-hour traf-fic, the elevator group control strongly affects...

Evacuation simulation of tall buildings
The evacuation of buildings is mostly based on using the stairs according to the current safety rules. In an emergency situation, elevators are returned to the main lobby and shut down. Special elevators may be reserved for firemen’s use to...
