3. Experimental method To achieve the first objective of this study, two experiments were carried out to study the exit choice behaviour of pedestrians during evacuation when they face either a real-life environment or a virtual environment. To achieve the second objective, we compared the commonalities and differences in exit choice between scenarios with different types of information in the VR experiments. Underneath these two experiments are further specified. First, the setup of the field experiment is described in Section 3.1. Accordingly, the setup of the VR experiment is detailed in Section 3.2.
