Reduce Occupant Diameter to Navigate Narrow Geometry

Reading Time: 1 minute

Created with software version: 2020.1

The new "Minimum Diameter" setting, shown below in Figure 1 for movement through narrow geometry (optional), specifies a diameter to which the occupants can squeeze their bodies to pass through a narrow area, such as narrow doors or corridors.

Occupants will reduce their diameter to this value only if the geometry would otherwise prevent them from further following their path. The default value of 33.00 cm is based on the maximum depth of a human body for 95th percentile of measured individuals, as published in (Pheasant, et al., 2005).
