Lift Traffic Intensity Calculator
Calculate up-peak handling capacity and expected interval for elevator banks using ISO 4190-6 methodology. Identify whether your lift configuration can handle peak demand.
Lift Traffic Intensity Calculator
Occupants served by this lift bank
Full loop from ground and back; typically 40–120 s
Enter building population and lift parameters to calculate traffic intensity.
HC% = (300 × capacity × loading × lifts) ÷ (RTT × population). Target ≥ 15% for office buildings per ISO 4190-6. Interval = RTT ÷ lifts.
Frequently Asked Questions
What is a good HC% for an office building?
ISO 4190-6 recommends ≥ 15% for standard commercial offices. Buildings with cafeterias or lecture theatres may need higher. Residential and hotel buildings can operate comfortably at 7–10%.
How is RTT estimated?
Round trip time = (floor-to-floor travel time × expected stops × 2) + door times + passenger transfer time. Dedicated lift simulation software is used for accurate RTT in large or complex buildings.
What loading factor should I use?
80% is standard for commercial office peaks; 70% for mixed-use; 50% for residential and hotels where arrivals are more spread out.
