ABSTRACT
A characteristic of balanced interfloor traffic is that there are larger demands made on the lift system in terms of the number of stops made by each lift. A good indicator of overall activity during interfloor traffic may well be the number of stops a lift is making. In the balanced interfloor traffic situation, the handling capacity of a lift system would be a less important parameter than for the uppeak and down peak traffic conditions, even if it had a meaning. The quality of service is more significant under interfloor traffic conditions as the lift system is expected to provide an excellent service in order to save occupants' time. A large number of simulation runs for a variety of lift configurations, demand levels, number of floors and supervisory control systems have allowed the assessment of the quality of service provided by a lift system under balanced interfloor traffic conditions.
