Available in PDF, EPUB and Kindle. Book excerpt: The ventilation system is an important element for the safety of a tunnel, as well as its investment and operating costs. Investors, operators and designers of road tunnels bear a responsibility for the safety of persons, as well as for important investment decisions. The new Road Tunnel Ventilation Compendium fosters understanding of basic aspects of ventilation in the context of tunnel safety, describes the actual state of the art and shows how to design and realise safer tunnels, at lower costs, with reliably functioning systems.

Download or read book Investigation of Effectiveness of Emergency Ventilation Strategies in the Event of Fires in Road Tunnels written by and published by . This book was released on 2005 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: A research project is being conducted at the National Research Council of Canada (NRC) to evaluate the effectiveness of current emergency ventilation strategies to control smoke spread in the event of a fire in two road tunnels. The research study includes numerical and experimental phases. The numerical phase uses Computational Fluid Dynamics (CFD) models to study smoke ventilation in the tunnels. The experimental phase is used to calibrate and to partially validate the chosen CFD models and to provide the necessary initial and boundary conditions. SOLVENT, a CFD model, was used to model ventilation scenarios using existing data. The current paper presents the efforts to validate the CFD model against onsite flow and fire test measurements conducted in a 1.8 km road tunnel. The CFD model includes aerodynamically significant physical features of the tunnel and is customized to provide general roughness replicating the actual roughness in the tunnel.

Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geographic Information Technology have raised the expectations of users. A static map is no longer enough; there is now demand for a dynamic representation. Time is of great importance when operating on real world geographical phenomena, especially when these are dynamic. Researchers in the field of Temporal Geographical Information Systems (TGIS) have been developing methods of incorporating time into geographical information systems. Spatio-temporal analysis embodies spatial modelling, spatio-temporal modelling and spatial reasoning and data mining. Advances in Spatio-Temporal Analysis contributes to the field of spatio-temporal analysis, presenting innovative ideas and examples that reflect current progress and achievements.

Book excerpt: In 1990 and 1995, PIARC published the calculation methodology and the emission factors for road tunnel ventilation design. An update of the existing PIARC methodology was necessary, as the emission standards of the vehicles were becoming more stringent and hence the vehicles cleaner. The old version described the emission situation up to the year 1995. This document has been produced by Working Group 2 of the PIARC Technical Committee on Road Tunnel Operations in the framework of its activities btween 2001 and 2003. Due to a steady tightening of emission laws for vehicles and changes in the risk assessment of tunnel fire, some design data may need constant updating. In this publication, new design information and some references are given for sizing longitudinal and transverse ventilation systems.

Download or read book Road Tunnels written by Fabio Borghetti and published by Springer. This book was released on 2019-03-27 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 work provides essential guidance on the following aspects: how a quantitative model can be implemented to evaluate risk in road tunnels; how to build an event tree for the accident scenarios considered; how to simulate the vehicle queue formation; how to simulate the evolution of accident scenarios; and how to simulate the users’ egress. Given its scope and depth of coverage, the book will be of interest to all engineers whose work involves fire protection and safety in tunnels, all persons engaged in safety and transport engineering or risk analysis for road tunnels, as well as public and private bodies involved in the application of Directive 2004/54/EC.
