Elevator Traffic Calculator
Static · formula-only · worked example computed when this page was built · no live data
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. Anything the worked example does not state uses this calculator's standard default; the interactive version shows every input and lets you change it.
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 by WorkHive's calculation engine when this page was built; standard: CIBSE Guide D:2015.
How to use this calculator
- Read the worked example. It uses a 10-floor office with 300 people served by two 13-person lifts at 1.5 m/s and shows every number in the method.
- Follow the formula with your own figures: it returns Interval, Handling capacity, Round-trip time, computed per CIBSE Guide D:2015.
- To compute interactively, open the Elevator Traffic Calculator inside WorkHive's free Engineering Design suite (link below). It runs the same method with your inputs.
FAQ
What is an elevator traffic analysis calculator interval?
The Elevator Traffic Calculator is a free online tool that 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 is free: this worked example is open to everyone, and the interactive calculator runs inside the free Engineering Design suite after a free sign-up (your work is saved to your account). WorkHive is a free, offline-first maintenance platform built for Philippine industrial plants.
