- W2559939834 abstract "Many road tunnels are comparatively short and a large number of them are in the range of 500 to 1’000 m of length or shorter. Such tunnels are typically longitudinally or naturally ventilated and have emergency exits at a distance in the range of 300 to 500 m. The detailed specifications vary from country to country. Risk analysis and experience show, that the safety level of such tunnels is frequently unsatisfactory, particularly in case of bi-directional traffic and tunnel slopes in the range of 2-3% or higher. This is basically related to the short time scales characterizing such tunnels, which can result in extremely rapid smoke propagation. This was tragically demonstrated e.g. in the fire in the Viamala tunnel (16 September 2006), on the Swiss A13 motorway. The present papers reviews some of the characteristics and safety-relevant weaknesses of the current design approaches for short tunnels, based on our design and design-support experience. We strongly feel that the current, guideline-oriented approaches need to be enhanced by genuinely risk-based methodologies, which allow for a clear identification of weaknesses and possible solutions. A further potential for improvement can be identified at the level of SCADA systems: faster and more integrated, “intelligent” automatic responses of all tunnel’s equipment will be provided by next generation’s SCADA technologies which are currently developed within the EU research project EMILI." @default.
