3-D route-planning support for navigation in a complex indoor environment

Three-dimensional (3-D) route-planning support offers a promising solution to overcome problems with wayfinding in complex indoor environments. An experiment was conducted to test the effect of 3-D route-planning support in a realistic setting, a large hospital building, during normal operation. Forty participants performed navigation tasks either with (n = 20) or without (n = 20) 3-D route-planning support. Support resulted in faster navigation, more use of artwork specifically installed to aid wayfinding, fewer navigation errors, less disorientation and less anxiety. In addition, participants used different strategies for wayfinding: without navigation support they used signs and route colour, but with navigation support they used not only the artwork, but also the existing furniture and other landmarks. The acceptance of 3-D route-planning support was high. Overall, the results support the value of 3-D route-planning support.

Human behaviour under fire situations in high-rise residential building

Purpose The purpose of this paper is to investigate human behaviour under a situation of fire in high-rise residential buildings and identify the factors that motivate people to evacuate. Design/methodology/approach A literature review was conducted to identify different factors of human behaviour during a situation of fire and identify challenges during the evacuation. Through a mixed research method approach, the paper identifies human background, experience and knowledge with fire safety. The paper discusses the challenges occupants face during evacuation based on previous evacuation experience and what occupants were doing during the fire alarm. Findings The paper has identified the challenges and the factors that affect occupants’ decision during fire emergency in high-rise residential buildings. It is clear from the findings that occupants have limited knowledge and skills on how to deal with fire emergencies. Occupants tend to depend on other evacuation routes. Occupants tend to ignore the fire alarm and usually they investigate if it is true or false. Originality/value The paper provides the knowledge and findings of occupants during fire emergency to fire engineers, facility managers, owners, and other professionals to assist during the design phase, and modify designs based on this findings of this research.
