MODELING SAFEST AND OPTIMAL EMERGENCY EVACUATION PLAN FOR LARGE-SCALE PEDESTRIANS ENVIRONMENTS

Large-scale events are always vulnerable to natural disasters and man-made chaos which poses great threat to crowd safety. Such events need an appropriate evacuation plan to alleviate the risk of causalities. We propose a modeling framework for large-scale evacuation of pedestrians during emergency situation. Proposed framework presents optimal and safest path evacuation for a hypothetical large-scale crowd scenario. The main aim is to provide the safest and nearest evacuation path because during disastrous situations there is possibility of exit gate blockade and directions of evacuees may have to be changed at run time. For this purpose run time diversions are given to evacuees to ensure their quick and safest exit. In this work, different evacuation algorithms are implemented and compared to determine the optimal solution in terms of evacuation time and crowd safety. The recommended framework incorporates Anylogic simulation environment to design complex spatial environment for large-scale pedestrians as agents.
