HBiF IAFSS W8 - From Disability to Heterogeneity

SUBSCRIBE TO OUR NEXT WEBINARS: https://forms.office.com/r/878uNLnYKf 20th of June 2023 This is the eighth event of a webinar series arranged by the permanent working group on Human Behaviour in Fires by the International Association for Fire Safety Science (IAFSS). Empirical experiments provide the basis for the parameterization of pedestrian movement. They are used to calculate the performance of buildings and, for example, to estimate times for safe egress. They are always in conflict between the necessary reduction of complexity and the scaling to real-life scenarios. The talk will outline the (long and difficult) journey of a transition from a focus on the impact of disabilities on the crowd movement as such to a rather comprehensive assessment of the heterogeneity of the crowd. The following topics will be covered in the talk: Short introduction into pedestrian dynamics research fundamentals of key performance values and the need for (as much as possible) homogeneous groups of people in empirical studies. What is happening inside a heterogeneous crowd? What is the difference between homogeneous and heterogeneous crowds, and why is it important to study them? Insights into empirical findings of small scaled studies on the influence of assistive devices on movement characteristics Movement studies considering heterogeneous characteristics. Lessons learned from two unannounced evacuation trainings considering occupants with disabilities. A discussion on the challenges, limitations, and imperfections of controlled experiments to describe complex systems as heterogeneous composed crowds. Dr. Geoerg is a research fellow at the Association of Fire Protection Engineering Germany (vfdb e.V.) and an engineering enthusiast for the empirics of pedestrian dynamics. His research focuses on the influence of individual heterogeneities on movement and its consequences on crowd movement characteristics. He is passionate about what individual characteristics in a crowd support safe, comfortable movement and how performance is affected. Paul will talk about how the movement of homogeneously and heterogeneously composed crowds differs, which phenomena can be observed, and which consequences this may have for consideration in evacuation planning. He advocates the courage to acknowledge people’s individuality and use it as an opportunity to create optimized conditions for entire systems. 00:00 Introduction by Enrico Ronchi 05:25 Presentation by Paul Geoerg 44:11 Open discussion
