TLDR
In this article, the authors present a framework for quantitative risk assessment which guides an integrated assessment of the risk components: hazard, exposure, vulnerability and consequences of a malfunctioning transportation infrastructure.Abstract:
Keeping transport links open in adverse conditions and being able to restore connections quickly after extreme events are important and demanding tasks for infrastructure owners/operators. This paper is developed within the H2020 project SAFEWAY, whose main goal is to increase the resilience of terrestrial transportation infrastructure. Risk-based approaches are excellent tools to aid in the decision-making process of planning maintenance and implementation of risk mitigation measures with the ultimate goal of reducing risk and increasing resilience. This paper presents a framework for quantitative risk assessment which guides an integrated assessment of the risk components: hazard, exposure, vulnerability and consequences of a malfunctioning transportation infrastructure. The paper guides the identification of failure modes for transportation infrastructure exposed to extreme events (natural and human-made) and provides models for and examples of hazard, vulnerability and risk assessment. Each assessment step must be made in coherence with the other risk components as an integral part of the risk assessment.read more

In-Plane Fragility and Parametric Analyses of Masonry Arch Bridges Exposed to Flood Hazard Using Surrogate Modeling Techniques
TL;DR: In this article , a stochastic parametric analysis based on the geotechnical properties of the soil components of masonry arch bridges located in Portugal was performed to assess bridge performance under a flood event, thus providing useful information for bridge management and monitoring.

Vulnerability and resilience of transport systems : A discussion of recent research
TL;DR: In this paper, the authors provide an overview of recent research on vulnerability and resilience of transport systems, and argue that more cross-disciplinary collaborations between authorities, operators and researchers would be desirable to transform this knowledge into practical strategies to strengthen the resilience of the transport system.

TL;DR: In this article, a review of existing cost assessment approaches for natural hazard risks is presented, where the authors consider droughts, floods, coastal and Alpine hazards, and examine different cost types, namely direct tangible damages, losses due to business interruption, indirect damages, and the costs of risk mitigation.

The impact of flooding on road transport: A depth-disruption function
TL;DR: In this paper, the authors developed a relationship between depth of standing water and vehicle speed to assess the disruptive impact of flooding on road transport, and incorporated this relationship into existing transport models to produce better estimates of flood induced delays.
