Analysis of Pedestrian Behavior for the Optimization of Evacuation Plans in Tall Buildings: Case Study Santiago, Chile

Abstract

Countries located in the Pacific Ring of Fire, such as Chile, require robust evacuation plans for tall buildings to manage the ongoing threat of natural disasters. This study presents a methodology for developing evacuation plans by conducting pedestrian movement simulations with agents that have a model of their surroundings. This approach allows us to assess different scenarios and choose the best option based on the specific characteristics of the site. The method combines simulation and data analysis, using the Monte Carlo method to improve emergency evacuations. Initially, Pathfinder software was employed to simulate the evacuation of a tall building. This involved modeling pedestrian movements using a multiagent system. These agents were programmed to behave like real pedestrians and make decisions during evacuation scenarios, providing valuable information. The effectiveness of two evacuation strategies was then evaluated using the simulation data. The proposed methodology was validated using a case study. The simulations showed that the best strategy depends on factors such as the distribution of people, the capacity of the exits, and the time available for evacuation. Finally, the model includes a training process that uses virtual reality technology to improve situational awareness.

Monte Carlo Analysis for Evacuation in Multipurpose Event Spaces

“…TET convj < TR TET (3) The aim of this study is to achieve consistent results in terms of the average evacuation times of people. Using the Monte Carlo method, it is possible to generate the desired number of variations (iterations) with random agent positions and profiles for all agents [16].…”

“…Ternero et al used the Monte Carlo method in their study to design fire evacuation plans for buildings in case of emergency [3]. In this study, two proposed evacuation strategies for a specific building (Faculty of Engineering-USACH) were evaluated using a combination of simulations and data analysis using the Monte Carlo method.…”
