The risk assessment for road tunnels
The number of tunnels used for transportation purposes around the world is steadily increasing to reduce the number of cars at street level. Given the possibly dramatic consequences of large fires occurring in tunnels, there is a need for assessing the level of risk in these infrastructures. Since the publication of the Directive 2004/54/EC of the European Parliament, risk assessment has become an integral part of tunnel design. Also a great number of road tunnel will be requalified in the next years. A risk assessment tool allows to evaluate design alternatives respect to the safety goals identifying the “best” solution.
