Research on Equilibrium Evacuation of Station Based on Improved Iterative Weighting Algorithm

Abstract

Evacuation efficiency is the key to ensuring safety in emergency situations. Combined with the connection structure of station facilities and pedestrian motion characteristics, an equilibrium evacuation model is constructed based on the reliability of evacuation time and a penalty rule. The model is solved by an improved iterative weighting algorithm. To verify the model validity, we simulate the evacuation process of Guomao Station and select evacuation time as the evaluation index. The simulation results show that the equilibrium evacuation model uses shorter evacuation time.
