Assessment of the Safety of Tunnels

This paper is the final report for the STOA project Assessment of the Safety of Tunnels. The paper draws to a great extent on a literature search concerning the current status of risk assessment in relation to tunnels. It also draws on many conversations held with experts world-wide and to a small extent on the results of a questionnaire which was distributed to experts. Finally, it draws upon the discussions at a Workshop held at the European Parliament, Brussels, on 16th May 2007.
