Dynamic Risk Analysis and Energy Saving in Tunnels

The technological innovation of systems in tunnels allows to reach high levels not only in energy efficiency but also in safety, where the legislation requires safety measures based on systematic considerations of all aspects of the system (infrastructure, operations, users, vehicles).In many existent tunnels, some structural safety measures could be implemented only through technical solutions with a disproportionate cost because of difficulties due to old infrastructures, unfavorable orographic situation or tunnels in sequence in wich simultaneously road works could cause a paralysis of traffic with unbearable economic and social costs. Therefore, a new layout of the SCADA system, able to perform a Dynamic Risk Analysis (DRA), has been developed to achieve immediate and effective benefits through the implementation of operational measures in Smart Tunnels in which advanced systems and sensors are installed. DRA can be associated with Energy Management Analysis (EMA) in order to perfectly fits within the "Industry 4.0" new European approach: through low costs it is possible to know real time what happens inside the tunnel, the environmental conditions, traffic data and system status (Smart Production), to apply operational measures in order to ensure the safety required (Smart Services) and to operate in energy saving mode whenever possible (Smart Energy).
