Book Synopsis Crowd Behavior Simulation of Pedestrians During Evacuation Process by : Noorhazlinda Abd Rahman
Download or read book Crowd Behavior Simulation of Pedestrians During Evacuation Process written by Noorhazlinda Abd Rahman. This book was released on 2018-09-04. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the use of the distinct element method (DEM) in modeling crowd behavior and simulating evacuation processes. Focusing on the mathematical computation of the uncertain behavior of evacuees, which is switching action behavior, it subsequently reproduces the crowd evacuation process under several conjectural scenarios using a DEM-based multi-agent model that has been modified by introducing the switching action behavior. The proposed switching action behavior model describes a person who has to change his/her destination due to the limited space capacity of the designated evacuation area. The change in the destination of a person is determined according to the motion of other individuals in the perception domain during the defined switching action time. The switching action time is formulated in the so-called switching action function, which is described by a convolution integral of the input and unit response functions. The newly developed switching action model is then validated using sensitivity analysis in which the primary focus is the crowd motion and flow of switching action behavior.

Book Synopsis Simulating Crowds in Egress Scenarios by : Vinícius J. Cassol
Download or read book Simulating Crowds in Egress Scenarios written by Vinícius J. Cassol. This book was released on 2017-12-08. Available in PDF, EPUB and Kindle. Book excerpt: This book describes, from a computer science viewpoint the software, methods of simulating and analysing crowds with a particular focus on the effects of panic in emergency situations. The power of modern technology impacts on modern life in multiple ways every day. A variety of scientific models and computational tools have been developed to improve human safety and comfort in built environments. In particular, understanding pedestrian behaviours during egress situations is of considerable importance in such contexts. Moreover, some places are built for large numbers of people (such as train stations and airports and high volume special activities such as sporting events). Simulating Crowds in Egress Scenarios discusses the use of computational crowd simulation to reproduce and evaluate egress performance in specific scenarios. Several case studies are included, evaluating the work and different analyses, and comparisons of simulation data versus data obtained from real-life experiments are given.

Book Synopsis Modeling and Simulation of Evacuation Plan for Hancock Stadium by : Nirmal N. Weerasekara
Download or read book Modeling and Simulation of Evacuation Plan for Hancock Stadium written by Nirmal N. Weerasekara. This book was released on 2015. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study is to use Modeling and Simulation of Evacuation Plan (MSEP) to support management to execute proper evacuation plan in case of emergency at Hancock Stadium in Illinois State University. Analyses of the research literature and evacuation scenarios are used to build a simulation system that will connect a description of emergency and evacuation situation with its context. It shows how an evacuation plan actually functions. The results of the study will help safety managers to understand the current situations of evacuation according to the specific simulation scenarios. The evacuation simulation is categorized according to the types of emergent situations and the number of evacuees. Each simulation is validated according to the real time data collected through observations and the published literatures. The practical implications of the research include the developed system to be used in case of emergencies and the experience gained will help future design of large-scale venues and facilities. This research innovatively used Building Information Modeling (BIM) technology, Dijkstra and Open Cleared Path algorithms, and Pedestrian Dynamics® simulation system for an open-space, steel structure in evacuation routes.

Book Synopsis City Evacuations: An Interdisciplinary Approach by : John Preston
Download or read book City Evacuations: An Interdisciplinary Approach written by John Preston. This book was released on 2014-08-01. Available in PDF, EPUB and Kindle. Book excerpt: Evacuating a city is a complex problem that involves issues of governance, preparedness education, warning, information sharing, population dynamics, resilience and recovery. As natural and anthropogenic threats to cities grow, it is an increasingly pressing problem for policy makers and practitioners. The book is the result of a unique interdisciplinary collaboration between researchers in the physical and social sciences to consider how an interdisciplinary approach can help plan for large scale evacuations. It draws on perspectives from physics, mathematics, organisation theory, economics, sociology and education. Importantly it goes beyond disciplinary boundaries and considers how interdisciplinary methods are necessary to approach a complex problem involving human actors and increasingly complex communications and transportation infrastructures. Using real world case studies and modelling the book considers new approaches to evacuation dynamics. It addresses questions of complexity, not only in terms of theory, but examining the latest challenges for cities and emergency responders. Factors such as social media, information quality and visualisation techniques are examined to consider the ‘new’ dynamics of warning and informing, evacuation and recovery.
