Real Time dynamic quantitative risk analysis approach for smart tunnel

According to the Directive 2004/54/EC and of the Italian transcription Decree 264/06 a risk analysis based design approach is required for tunnel systems for which minimum safety measures does not bring to sufficient safety level. In 2022, the complex systems related sustainability affects each field of study, especially engineering. As konwn, tunnel is a very particular infrastructure in terms of energy consumption and safety issues related to the high level of risk determined by the consequences induced by a potential fire event. The energy consumption related to the safety systems for tunnel ventilation, traffic management, lighting, and communications is a key point for a sustainable design and requires a new idea of “SMART TUNNEL” in the framework of an holistic approach helps in solving in one time the safety and energy issues. In order to evaluate the sustainability goals of tunnel safety design, Quantitative Risk Analysis allows to calculate real time risk level due to traffic, meteorological conditions, and the dependability of the safety subsystems, to define the emergency management procedures (emergency planning), for fire extinguishing, ventilation, communication systems and traffic management. This approach allows minimum energy requirements according to the synthesis of sustainable safety requirements. The paper also introduces another concept: GREEN TUNNEL Green is compliant with the production of energy required by means of renewable sources. This article suggests Real Time Dynamic Quantitative Risk Analysis (RTDQRA) in order to verify the compliance to societal acceptability criteria and to territorial resilience target.
