As with the Technical Committees mentioned above, the subject of resilience will also be dealt with in a separate issue in Technical Committee 4.4 "Tunnels", where both the construction and maintenance as well as the future use of data-driven approaches for preventive and/or predictive maintenance are addressed. Operating and ensuring the safety of users is a major challenge for owners and operators of road tunnels. Therefore, best practice approaches and successful solutions for the safe operation of heavily traffic urban tunnels as well as the impact of new propulsion technologies on tunnel operation and safety will be investigated. Further work of Technical Committee will address ITS applications for tunnels including the identification of the potential of big data and data analytics applications for the operation of road tunnels as well as the update and improvement of the DG-QRAM risk assessment software for the transport of dangerous goods in tunnels. The results of the work will then also be incorporated into the further development of the Road Tunnels Manual. (extract from the Strategic Plan)
