Abstract

This study explores how able-bodied individuals behave during evacuation in underground metro station in the presence of disabled person. Metro station plays a crucial role in urban transportation but also had significant challenges due to improper layout, high crowd density and including vulnerable populations such as the elderly and disabled. To found evacuation pattern, many advanced technologies are used in this research such as Agent based modeling in Unity 3D for behavioral simulation and for design of 3D model of metro station, SketchUp Pro is used. A 2³ full factorial experimental design was adopted and it include three main factors (number of evacuees, number of disabled people, presence of liftman) resulting in eight different evacuation scenarios. It was found that, the simulation revealed that evacuation time increased by as much as 35.5% with higher crowd density, higher number of people and disabled individuals. The presence of liftman reduced delays by 17.7%. A systematically survey data collected from 100 participants, analyzed by using, ANOVA, Tukey’s HSD and regression analysis (adjusted R² = 0.82) And PCA. The finding showed that crowd congestion, signage etc. affect evacuation behavior. The study is done with the help of BIM and VR, which gives helpful ideas for making more safer metro station for everyone during emergencies.
