If we truly want to account for the population at a disadvantage in evacuation, there is only this much we can do with the current approach... Pre-evacuation time distributions, walking speeds, and so on only tell us a part of the story - the story of your average person within an average population, with an average walking speed and average response. While these models are undoubtedly useful in engineering, there is perhaps a better way.

My friend and guest Enrico Ronchi is trying to find this way through his new ERC Consolidator grant, "Egressibility: a paradigm shift in evacuation research". In this grant, instead of following the main path, he is focusing on stuff we do not know - how to characterise disabilities and understand them better (also through the lens of health and medicine), how to quantify the disadvantages at large, and how to solve potential issues for those who those at the largest risk.

In this episode, you will learn about Enrico's ideas and the edge of the knowledge we have today. Some key points covered are:

• Insights on paradigm shifts in evacuation science
• Introduction of the concept of "egressibility"
• Importance of understanding functional limitations in emergencies
• Shift from agent-based models to inclusive data-driven models
• Use of technology, like VR, for immersive research experiences
• Need for changes in regulations for better evacuation safety
