Research on Safe Evacuation Simulation of University Students’ Dormitory Buildings Based on Pathfinder

In this paper, a study on simulation of a boys’ dormitory building evacuation in case of emergency is carried out, using the evacuation simulation software Pathfinder 2011. With parameters set on the basis of the establishment of building models and their respective personnel, with the Steering model selected, and with different numbers of exits, the simulation results show that the time and evacuation numbers linearly correspond in a particular relationship; the rate of change of evacuation time along with the number of evacuations undergo dynamic growth in a certain number of intervals. Using the condition of saturation of evacuees, and carrying out the simulation and analysis of different numbers of exits, evacuees, and evacuation styles, where and when the highest risks are can be demonstrated, so as to optimize evacuations.
