Improving Resilience of Road Networks - Framework

Sustainable development of societies is increasingly relying on unrestricted performance of terrestrial transportation networks. However, the recent sudden failures of the Polcevera viaduct in Genoa, Italy [1], a suspension bridge in France [2] and the Ponte di Caprigliola bridge in Liguria, Italy [3], are painful reminders of oncoming threats to performance of traffic networks. These reminders are fortunately quite rare, but they emphasize the need to ensure safe and reliable infrastructure, by continuous improvements of maintenance planning.
