Elevator Traffic Calculator
The Elevator Traffic Calculator finds the round-trip time, interval, and 5-minute handling capacity for a lift group. Example: for a 10-floor office with 300 people served by two 13-person lifts at 1.5 m/s, Interval = 48.2 s, Handling capacity = 20.7 %, Round-trip time = 96.5 s (per CIBSE Guide D:2015).
How it works
Computed from your inputs per CIBSE Guide D:2015.
Worked example (Vertical Transport)
Inputs: a 10-floor office with 300 people served by two 13-person lifts at 1.5 m/s.
| Result | Value |
|---|---|
| Interval | 48.2 s |
| Handling capacity | 20.7 % |
| Round-trip time | 96.5 s |
Computed live by WorkHive's calculation engine; standard: CIBSE Guide D:2015.
How to use this calculator
- Enter the figures for the duty you are sizing: the worked example below uses a 10-floor office with 300 people served by two 13-person lifts at 1.5 m/s.
- The calculator returns Interval, Handling capacity, Round-trip time, computed per CIBSE Guide D:2015.
- Check the worked example to confirm the method matches how you would do it by hand, then run your own numbers in the interactive tool.
FAQ
What is a elevator traffic analysis calculator interval?
The Elevator Traffic Calculator is a free online tool that computes finds the round-trip time, interval, and 5-minute handling capacity for a lift group. It shows the formula and a fully worked example so you can check the method, not just the number.
How is it calculated?
The result is computed from your inputs following CIBSE Guide D:2015. The worked example on this page shows a real computation with real numbers.
Is the calculator free?
Yes. WorkHive's engineering calculators are free to use, no sign-up needed for the tools. WorkHive is a free, offline-first maintenance platform built for Philippine industrial plants.
