“Societies and businesses rely heavily on transportation infrastructure. Thus, the reliable assessment of their vulnerability and the associated risks to critical hazards is an urgent need of paramount importance toward resilient transportation networks.”




examples of bridge failure due to hydraulic hazards (e.g. scour, debris accumulation, drag forces)

In response to the above urgent need we deliver solutions for the Quantitative Risk Assessment of transportation infrastructure, by integrating:

  • adaptive fragility models that account for the deterioration of assets (ageing and previous hazard effects) and  improvements (retrofitting/strengthening)
  • risk and loss assessment of transportation networks exposed to natural hazards, toward efficient allocation of resources in decision-makingand disaster management
  • advanced numerical models of transportation systems of assets subjected to critical combinations of geo- and climatic hazards
  • diverse transportation assets: bridges, embankments, cuts, tunnels, retaining structures
  • multiple hazards: floods, hydraulic actions, earthquakes, landslides, ground movements
