Abstract

With economic development and pandemic relief, crowd gatherings have become a focal point. Despite academic interest in crowd evacuation due to sudden events, the influence of exit obstacles has been neglected. This paper builds on prior research, presenting a social force model for emergency crowd evacuation under obstacle diversion. It explores the diverse effects of various obstacles on evacuation efficiency through experiments, mathematical modeling, and simulations. The study aims to offer scientific insights for urban planning based on the analysis of evacuation outcomes under different obstacle configurations.
