Modelling of impact of fire on safe people evacuation in tunnel
نویسندگان
چکیده
In this paper, the use of Fire Dynamics Simulator (FDS) and its evacuation module, Evac for modelling fire and people evacuation in a road tunnel is illustrated. For given fire scenario and traffic situation in the tunnel, behaviour of individual evacuees as well as groups of evacuees is analyzed in order to demonstrate the impact of fire on people evacuation. Some specific features of the use of FDS+Evac for simulation of people evacuation in case of tunnel fire are also discussed.

Factors Influencing Failure Emergency Evacuation in Work Environments during Fire
One of the necessary measures of saving human life in emergency situations, such as fires, is the safe and swift evacuation of people. The prerequisites for this are to anticipate, identify, and eliminate factors preventing people from leaving buildings in a timely and safe manner while moving them to a safe place [1]. The occurrence of errors caused by engineering, design, human, and psycholog...
متن کاملModelling the Evacuation of People from a Train on Fire in a Railway Tunnel
Fire safety of each structure consists in the creation of conditions for rapid and safe people evacuation, in the limitation of spread of fire and combustion products in the structure and the surroundings of the structure, and in the creation of conditions for rapid, effective and safe response actions of rescue units. In case of fire on a passenger train standing in a tunnel, a top priority ta...
متن کاملSimulation of the course of evacuation in tunnel fire conditions by FDS+Evac
In this paper, simulation of fire in a short 2-lane road tunnel and its evacuation are described. Two traffic situations in the tunnel and their impact on people evacuation in fire conditions are analyzed. For simulation of the tunnel fire, the FDS (Fire Dynamics Simulator) system, version 5.5.3 based on advanced CFD (Computational Fluid Dynamics) fire model is used. The evacuation of people in...
