Nowadays, the evacuation of pedestrian crowd in indoor building environments poses a critical challenge for architects and safety engineers. In this study, pedestrian evacuation from a building is simulated using a social force model. For this purpose, the simulation incorporates various factors, including the building layout (location of walls, columns, and exits), the obstacle arrangement (desks and chairs), the spatial distribution and gender of pedestrains, as well as the mass of their bags are considered. Accordingly, pedestrian gender—and consequently their height and body mass—as well as their bag mass, which affect their walking speed, are modeled. In addition, the evacuation process is based on the pedestrians’ decision-making to assign to the nearest exit and incorporating awareness and knowledge throughout the evacuation. The proposed method evaluates evacuation performance based on total evacuation time, crowd density, and pedestrians speed, using real-world data from the School of Surveying and Geospatial Engineering at the University of Tehran. The results indicate that accounting for gender diversity, decision-making and bag load reduces the evacuation time by 26.08% compared to a homogeneous baseline model. This indicates the importance of consideting gender, bag load, as well as decision-making based on pedestrian awareness in evacuation modeling to increase realism.
