Occupancy Estimator

The Occupancy Estimator helps estimate the socially-distanced capacity of a venue, or of discrete spaces within that venue. This is important as socially-distanced capacity is often very much less than a venue or a space's Occupancy Rating (the number of people normally allowed inside the venue or space).

You can optionally subdivide a venue’s accessible spaces into specific Spaces (herein called demarcating), where each Space represents a different pedestrian space of a venue. For instance, a train station has many different types of pedestrian spaces.

  • Concourses
  • Walkways
  • Vertical circulation
  • Vertical circulation runoff areas
  • Gates
  • Gate queueing
  • Platforms

Spaces can also be defined on a floor-by-floor basis, or you can just use the model's accessible spaces as-is without demarcation. You are free to demarcate Spaces as appropriate to your specific goals.

The Occupancy Estimator estimates the upper occupancy limits based on social distancing requirements, using the circle-occupancy methods described in the Capacity Calculator .

  • The estimates are conservative, they do not try to optimally pack people into a space to maximise occupancy.
    • The aim is to provide safe estimates, not exact counts.
  • It accounts for Occupancy Rating and Capacity Factor, where known and/or requirements.
  • Occupancy Rating is optional. If not known/required, the tool can provide estimates that aren't qualified against Occupancy Rating.
  • Calculation method is the two estimate methods used for capacity calculation (as described in Capacity by Density tool)
To start the command, use any of these methods:
  1. Open the Tools menu. Select the Social Distancing > Occupancy Estimator option.
  2. In the Social Distancing toolbar, click the Occupancy Estimator button .
  3. At the command prompt, type occupancyestimator.
