Human Behavior Research

Fire safety design for buildings incorporates technology and materials to protect occupants, but often falls short in its consideration human evacuation dynamics. Until now, the evacuation dynamics of children have largely been ignored as the vast majority of data and…
The attacks on the World Trade Center in 2001 caused a new assessment into high-rise building safety and emergency procedures. This report identifies key behavioral factors and group dynamics affecting people during a high-rise building fire, reviews the current procedures…
Exit selection during an emergency evacuation depends partly on individual behavior. In this project, three individual behavior types are considered: conservative, active, and herding. The distribution of these individual behavior types will vary depending on venue, and these distribution differences…
Wayfinding describes the process by which an individual inside a building chooses a route to safety. In most evacuation modeling tools, wayfinding is mostly ignored and occupants are assumed to choose the shortest path to safety. This study involved participants…
The level of safety that a building affords occupants during a fire is based on regulatory codes or design. However, few of these regulations are based on a scientific understanding of how occupants will react during an emergency. For a…
NRIFD performed this investigation to meet the challenge of developing fire alarm and notification systems for people with hearing difficulties. It was determined that an alarm sound with a wide bandwidth, like an electromagnetic buzzer or a sweep, is more…
Evacuation models are used to calculate the time required to evacuate a building. Due to a lack of data and theory on occupant behavior for use in evacuation models, evacuation models make assumption and simplifications about occupant behavior that inappropriately…
