Agent-based simulation of alternative classroom evacuation scenarios

Abstract

Due to the growing number of emergency accidents occurring around students,evacuation issues have become significantly important for both school officials and architects. Simply following construction codes cannot ensure that a building's layout is suitable for evacuation behaviors; therefore, to discover the suitable planning schemes, we have introduced an agent-based simulation model via Netlogo to investigate the interrelationships between evacuation efficiency and classroom layouts. Before conducting modeling experiments, both the simulation structure and the sensitivity to its parameter settings are examined by validation research and sensitivity analysis. Furthermore,to demonstrate the importance of conducting fire drills with students, two differen ttypes of behavior rules are designed to reflect the distinctive characteristics of students evacuating without instructions and students evacuating in good order.The general comparison results show us that the classroom layout with two exits shortens students' evacuation time, and the premeditated behavior rules, meaning that students who follow preset instructions to arrange their activities, not only escape faster but also have some advantages in ensuring their safety during the evacuation process. Moreover, at the end of this paper, several methods of improving this simulation model are proposed for more complex research in the future.
