Abstract
Worldwide many new road tunnels are planned and under construction. Besides, international regulations, recommendations and guidelines are being developed. Many countries agree on the fact that there is a need for a framework in which all relevant aspects of tunnel safety, such as regulations, infrastructure and operational safety features, safety assessment, tunnel use, operating experiences and safety management, are taken into account in an holistic way. The purpose of this report is to fulfill this need, which was also anticipated within EU projects. (Author/publisher)
