Abstract

To study the evacuation from rail tunnels is vital for saving human lives when trains are forced to stop inside the tunnel due to fire or other incidents. Although NFPA 130 standard has given limited suggestions on the design of means of egress in rail tunnels, very rare other references can be found about the tunnel evacuation so far. In this paper, an agent based continuous crowd simulation model was developed to study the evacuation from rail tunnel with cross-passageways. This study has focused on the influence of the walkway width and cross-passageway spacing on the egress time and queuing patterns during the evacuation. In our simulation, it was found that if the width of walkway was added by every 100 mm, the egress time would decrease accordingly, but with different sensitivity at different width. The continuous model was proved to be eligible for identifying the continuously change of the dimensions of egress element. The study also revealed that the distance between cross-passageways was highly relevant to the optimized evacuation route choice strategy and certainly was an important parameter for egress time.
