SOLIT - Safety Of Life In Tunnels

The research project SOLIT² is focused on the COMPENSATION of traditional security measures in road tunnels by fixed fire fighting systems (FFFS) and their integration into an existing tunnel safety system.
The project is funded by the Federal Ministry of Economics and Technology of Germany and has undergone continuous development since its start in the end of 2009. Based on a comprehensive status analysis on existing FFFS in tunnels and their goals, the partners of the consortium FOGTEC, STUVA BUNG, Ruhr University Bochum and the TÜV Süd, examine which options exist to replace conventional safety systems in road tunnels partially by FFFS. The main focus hereby is on water based FFFS.

The goal is to advance the technical feasibility, particularly in retrofit applications, the cost savings, as well as the possible increase in safety levels. In the context of the project the qualitative and quantitative verification of the effectiveness will be developed with the help of simulations and large-scale fire tests on a 1:1 scale. In addition, there is also a comparison of the reliability characteristics and life cycle costs of conventional systems and FFFS in tunnels.

The results are summarized in an ongoing planning guidance for planners, operators and experts.

Various workshops take place in autumn this year. The implementation of the SOLIT guideline can be discussed together with the partners of the consortium during these workshops. The exact time schedule and application procedure will be published soon on this web page!
