Decision support framework for terrestrial transportation infrastructure – Resilience approach

The EU-funded HORIZON 2020 project SAFEWAY aims to design, validate and implement holistic methods, strategies, tools and technical interventions to increase resilience of terrestrial transport infrastructure in the face of natural and man-made hazards. The basis for the project is establishing a robust decision support framework which can utilize remotely monitored data on hazards, infrastructure condition and traffic, to yield knowledge on the dynamics of relevant risk factors associated with potential asset failure scenarios. The first task of the framework is elaborating a value system regarding network resilience, based on monetized direct and indirect consequences of inadequate asset performance. Here, the quantitative risk assessment is will be used to estimate the expected loss of benefit of infrastructure due to failures for both single mode and for multi-modal transportation. The benefits of possible maintenance strategies can be expressed as discounted risk reduction, which in turn can be understood as maximizing resilience.
