Перевести. The majority of elevator designs are developed from Up Peak Round Trip Time calculations as described in the following publications:- CIBSE Guide D: Transportation Systems in Building Elevator Traffic Handbook, Theory and Practice. Gina Barney. The Vertical Transportation Handbook. George Strakosch.
Traditionally, these calculations have formed the basis of establishing the Handing Capacity of an elevator system.
Modern installations with more complex elevator arrangements have led to the development of more specific formula such as the General Analysis calculation.
Subsequently, this has been exceeded for Double Deck elevators.
Otis Elevator Company operates more that 1.9 million elevators worldwide, giving rise to its claim that the equipment of the world population is transported by its products every fire days.
Elevator traffic simulation software can be used to model complex traffic patterns and elevator arrangements that cannot necessarily be analysed by RTT calculations.
There are four main types of elevator traffic patterns that can be observed in most modern office installations. They are up peak traffic, down peak traffic, lunch time (two way) traffic and interfloor traffic.
