This simplified resilience assessment for road projects was presented at the XVIth World Winter Service and Road Resilience Congress in Calgary in February 2022. We call his method the 3R-method because we use three Rs, robustness, redundancy and recovery as a measure of resilience
The Norwegian Public Roads Administration NRPA is to have an overview of the threats to and the vulnerability of the road network, and work across its own organsation (and together with other agencies) in necessary contingency planning in order to ensure the best possible accessibility under changing conditions and/or possible or actual threats. How?
This paper describes an infrastructure risk analysis model, considering possible threats and potential impacts. Their model follows the commonly accepted risk assessment method of fault and event trees.
In this paper safety and security are brought together in a unifying risk and vulnerability framework that covers both accidental and malicious events.
Today’s paper describes how Finland views logistics and supply as important to national security and how the LOGHU project was created to develop a framework for identification and ranking of threats and corresponding countermeasures.
Supply chains are increasingly becoming complex webs and networks and are no longer straightforward chains with just a few links between supplier and customer.
Today we are going back in time, to one of the seminal articles in road vulnerability. It is a conceptual paper that provides the basis for why road vulnerability needs to be a more important issue .
It is important to distinguish to between criticality and vulnerability when assessing the importance of the road and highway network. Collectively, these factors are an indication of the conditions, concerns, consequences, and capabilities that might cause an operating agency to label an asset “critical.”
The paper defines the concept of vulnerability as it applies to production systems and is built around three concepts: A taxonomy of vulnerability factors as a basis for or guideline in establishing scenarios.
An input/output model to describe production systems.
A two-step vulnerability analysis for productions systems.
A reliable transportation network represents a net benefit to society, and conversely, a vulnerable network represents a net cost to society. Hence, vulnerability ought to be an important parameter for decision-support in cost-benefit analyses, by seeking to establish a link between the terms reliability and vulnerability vis-à-vis costs and benefits.
