To improve the ecological validity of pedestrian
evacuation under fire in highway tunnels, a 6DoF pedestrian evacuation
experimental system based on the virtual reality(VR) allinone machine
embedded with Insideout positioning for highway
tunnels is developed. When the system was applied to the experiment, the
participants could get away from the constraints of mouse, handle, and other
control modes as well as equipment cables. The experiment was completed using
perception information and autonomous action of 6DoF in the virtual scene, and
the system could obtain the speed characteristic data of the participants
through realtime tracking and positioning. To validate
its effectiveness, the system was used to conduct evacuation experiments in
three scenarios: real open space, virtual empty tunnel, and virtual fire
accident tunnel. The data of 30 participants in different scenarios, including
movement speed, movement track, emotional response, immersion sense, and
presence sense, were collected. The experimental results of the real empty
space tunnel and virtual empty tunnel, and virtual empty tunnel and virtual
fire accident tunnel were compared. The experimental results indicate the
following: (1) The headwearing VR device did not cause
vertigo to participants. (2) The participants had a strong sense of presence in
the virtual fire scene, and the characteristics of their emotional response,
moving track, and moving speed were consistent with those in the real scene,
indicating that the system has good application effectiveness.
