Tittle: Assessing the navigation error characteristics of residents and tourists during evacuation – a combined simulation and virtual reality approach

Abstract: During evacuation, the evacuees are required to follow the fastest and safest path to the designated evacuation site. However, navigation errors due to lack of knowledge, signage presence and the evacuee behavior are affecting the evacuation efficiency. For that, it is imperative to assess these navigation errors and to develop an optimization model in order to increase the evacuation reliability by improving the guidance at key intersections. This is done by minimizing the difference between the deterministic shortest path and the stochastic shortest path with the stochasticity associated with the selection of an arc at each node, and the behavior of the evacuee. For that, we developed two components: 1) a MATSim based evacuation model, a random (or probabilistic) walk, in which the evacuees are dynamically selecting their next road section probabilistically, and 2) a virtual reality (VR) navigation challenge which investigate the decision-making during evacuation.
