This chapter describes the implementation process of the F-N curve, which makes possible to represent the societal risk and subsequently verify its acceptance with respect to the ALARP criterion. The F-N curve is evaluated starting from the frequencies of occurrence of the accidental events and the number of fatalities determined by each accidental scenario.

This chapter describes model calibration in order to verify its consistency. The sensitivity analysis carried out on the parameters and measures considered in the proposed model is described, with the aim of analysing their effect of the shape and position of the F-N curve. In addition, the result of a comparison made using QRAM software and carried out on three tunnels considered to be representative is illustrated.

This chapter describes the approach used to determine the evolution of the consequences for each of the accidental scenarios considered in the risk analysis procedure. The consequence analysis allows to estimate which are the negative effects of the accidents that can affect both the egress and tenability of tunnel users.

This research project considers a quantitative model for analysing the accessibility of open- air stretches of a railway line in emergency conditions using the road system (Borghetti, 2014). The project derives from a previous study (Borghetti and Malavasi, 2016) which illustrated the problems regarding the vulnerability of a railway stretch with particular reference to accessibility in emergency conditions; a method for evaluating accessibility was proposed, with reference to a specific territorial situation. This work will examine in detail the analytic structure of the individual indicators that make up the model.\ud An Accessibility Index was determined for each railway link i of homogeneous length, starting from an evaluation of the territorial and contextual characteristics in which the line is positioned. The analysis procedure consists firstly of identifying those parameters that compete in implementation of the Accessibility Index, and secondly in aggregating the Indicator parameters which, through the use of relatively important weights, are part of Index determination.\ud The model is based on a comparative approach that places the Accessibility Index in relation to the links that make up a railway stretch, therefore identifying the priorities and a hierarchy of the management and/or infrastructural interventions carried out to improve accessibility should important events occur

In this chapter it is introduced a simple methodology for the quantitative assessment of the severity of the expected consequences of a tunnel fire that can be applied in any complex environment. The proposed methodology was applied to the Morgex North tunnel to show its potentiality for evaluating the effect of different geometric characteristics on the safety performances of a tunnel in the event of an unwanted fire.

In this chapter are presented the experiments and experimental measurements obtained in the two full-scale fire tests performed in the Morgex North tunnel, where both the HRR and ventilation velocity were measured as a function of time. It is initially described how the fire scenarios were designed and operated, then the obtained experimental results are presented and compared to the numerical predictions of CFD simulations of the same fire scenarios. In this chapter the discussion is initially focused on the comparison with analytical models and empirical correlations based on theoretical analysis and literature measurements obtained in other tunnel fire tests. The Morgex fire tests allowed to collect different measurements (temperature, air velocity, smoke composition, pollutant species) useful for validating and improving new and existing CFD codes and for testing the real behaviour of a tunnel and its safety systems during a diesel oil fire with a significant Heat Release Rate (HRR).

After presenting the Morgex North tunnel, location of the full-scale fire tests, the choices made for the implementation of the fire test, made up by two fire scenarios, are deeply described. The idea of this part of the book is to give possible stakeholders useful suggestions in order to guide them in the preparation of a similar experience. Indications are given about fire scenarios and their preparation, safety issues, materials and equipment, preparation and location of measuring instruments.

The DESTINATION project, operating since 2010, proposed as its primary objective the implementation of a new information system called GIIS (Global Integrated Information System). The GIIS provides a platform for the sharing and analysis of data concerning dangerous goods transportation within the territories of the project: Canton Ticino, Piedmont Region, Lombardy Region, Autonomous Region of Aosta Valley and Autonomous Province of Bolzano Alto Adige. The GIIS is based on a risk analysis model related to the transport of dangerous goods, which is able to consider both human and environmental targets that are potentially exposed. The article describes the approach used to assess possible environmental targets in a consistent way with the goals of the project. By applying the AHP methodology, a weighting coefficient for non-human targets is defined, in order to homogenize the units of measurement of the potential damages of the exposed environmental targets, as well as to allow the algebraic sum of the risks.
