The article deals with risk analysis of road tunnels using state of the art PIARC - OECD methodology and points out its limitations. It has been shown how to upgrade the methodology by combining it with modelling and simulationg critical accident scenarios in road tunnels. This way specific risk reduction measures, which are not included in the methodology can be assessed and used to additionally minimize risk of accidents involving large number of fatalities.

The article deals with establishment of performance-based fire safety. Cruical tool to achieve this are computer simulations whose results are greatly influenced by the input data which have to represent realistic scenarios. Considering stochastic nature of fires, input data have to be statistically validated. By doing this, greater reliability of the results can be achieved.

Ventilation systems in semi-enclosed spaces, such as tunnels, are of crucial importance for maintenance of sufficient air quality during normal and emergency conditions. During fire accidents smoke exhaustion is crucial for evacuation and rescue. The monograph assesses different types of tunnel ventilation systems and control of ventilation during emergency conditions. Effectiveness and reliability are crucial during tunnel fires and other emergency situations. Interactions between ventilation and fire fighting systems and other tunnel equipment are analyzed.

The article describes novel approach in ventilation of bi-directional tunnel without building of additional ventilation tube that is very costly. We have proven that it is possible to sufficiently extract smoke from long road tunnels with described approach that has been verified by simulating fires with different heat release rates using 1D and 3D CFD models.
