Grouping behaviour and decision making in road tunnels evacuation in smoke conditions Experimental approach

Jarosław Wąs, Jakub Porzycki, Natalia Schmidt-Polończyk


We have performed a set of evacuation experiments in a road tunnel. In each experiment pedestrians were gathered in a bus, the bus was stopped in the tunnel, next the tunnel was filled with artificial smoke and pedestrians had to evacuate. We compared evacuation times and behaviours for different levels of visibility, defined by extinction coefficient Cs range.
