Method — Screening-level estimate
A population and handling-interval screen against a nominal number of cars. NOT a lift traffic study, and no shaft structural design is produced.
Every result below is produced by the same engineering engine that feeds the High-Rise reference project, so a quantity taken from this page and a quantity taken from the workflow cannot disagree.
Governing Formula
Governing Formula
N_cars = ceil(P_peak / (carCap x rounds)) Where:
-
P= Peak 5-minute population [persons] -
cap= Car capacity [persons]
Derived Equations:
Round trips per interval:
rounds = (interval x 60) / cycle Design population:
P_design = n x persons x factor Shaft construction:
A_shaft = shaft_perimeter x height x lifts Assumptions & Limitations
- No five-minute traffic simulation, no car allocation, no express or double-deck options.
- No shaft structural design, no machine-room or pit structure, no lift order-of-procurement lead time.
- A minimum of one lift per 25 levels is applied so very tall, low-population towers stay serviceable.
