Abstract

Transport infrastructure resilience and risk assessment is typically based on the assessment of individual assets rather than the entire system. We introduce the concept of the infrastructure System of Assets (SoA), or ecosystem, referring to non-urban roads, illustrate the individual elements of the system, and the geotechnical and climatic hazards to which it is subject. The infrastructure is classified based on: (i) the road capacity and speed limits and (ii) the geomorphological and topographical conditions. This classification covers the majority of non-urban networks, exposed to hazards such as earthquakes, floods, landslides (including slides, debris flow and rock fall), extreme temperatures and shrink/swell phenomena. This approach forms the basis for an integrated assessment of the fragility of the SoA rather than the individual elements. Numerical fragility curves are introduced, to articulate the vulnerability of the SoA, to various geohazards and a case study is presented for a bridge exposed to multiple hazards. This framework can contribute to future developments in the resilience management of the transportation network in respect of geotechnical and climatic hazards.
