主 题:Road tunnels Resilience Refurbishment works Traffic simulation Digital technologies
摘 要:After some tragic fire events,Directive 2004/54/EC was issued to ensure a minimum safety level for tunnels belonging to the Trans-European Road Network longer than 500 ***,most of the Italian road tunnels are still not in compliance with the minimum safety requirements,thus refurbishment works are often *** developing a traffic macro-simulation model,this paper aims at assessing the resilience of an existing twin-tube motorway tunnel when one of its tubes is partially or completely closed due to planned *** scenarios were investigated,also considering the availability or not of an alternative itinerary in the surrounding transportation *** average vehicles’speed was used as a functionality parameter,while the resilience metrics were the resilience loss,the recovery speed,and the resilience *** findings showed higher resilience losses for complete closure rather than partial closure of the tube under planned refurbishment *** implementation of digital technologies,such as variable message signs,might reduce the resilience loss of the tunnel *** research might represent a reference for tunnel management agencies in the choice of the most appropriate traffic control strategy to improve tunnel resilience in the event of planned activities.
