This book illustrates a new quantitative risk analysis model for road tunnels that is capable of evaluating the role of infrastructure measures, equipment and management procedures as prescribed by EU Directive 2004/54/EC. The risk assessment draws on the typical F-N curves of societal risk, evaluated with the help of event tree analysis, vehicle queue formation dynamics, and users’ egress and tenability models. In addition, the model considers the reliability of the safety measures. The w...

This book aims to cast light on all aspects of tunnel fires, based on experimental activities and theoretical and computational fluid dynamics (CFD) analyses. In particular, the authors describe a transient full-scale fire test (~15 MW), explaining how they designed and performed the experimental activity inside the Morgex North tunnel in Italy. The entire organization of the experiment is described, from preliminary evaluations to the solutions found for management of operational difficul...

This book showcases the discussion about megaprojects carried out at the MeRIT (Megaproject Research Interdisciplinary Team) workshop 2024: the crisis, discontinuity, rising prices, and supply chains disruption force radical reflection for those involved in megaprojects. It raises a modern-day challenge, the creation of value for stakeholders. Indeed, the aim of the volume is to encourage readers to think more broadly, articulately and less stringently than the mainstream claims. There is ...
