General Analysis Double Decker Lift Calculations

Richard D Peters

Wednesday 1st March 1995

The formulae presented in this paper allow analysis of any peak passenger traffic flow for any practical configuration of double decker lifts. A Poisson approximation of passenger arrivals at lift landing stations is assumed, enabling the derivation of formulae for probable number of stops and average reversal floors during a lift round trip. Double decker round trip time calculations yield analysis results in terms of coincident stops, waiting interval, handling capacity and capacity factor. Derivation and implementation of the General Analysis formulae are discussed. Examples are analysed using the Oasys LIFT program which utilises the formulae.
