Assessment of Climate Change Impacts and Adaptation for Inland Transport
Room: South Hall 3C, 3rd floor
The provision of adequate service level is the key objective of work of road asset managers. That service level should be provided despite various hazards, including such coming from climate change. Is however the road asset resilient to these hazards? What are the tools available to road asset managers to understand the degree of road resilience?
This foresight session presented stress tests as tools for assessing the level of resilience of a selected road asset or road network to climate change hazard.
In this context, the session discussed road transport asset/network, observed impacts of climate change on road assets/networks, road asset/network service level and economically optimal level of risk. It also discussed costs and benefits associated with the managed road asset/network with and without intervention programme.
As far as stress tests are concerned, this foresight session clarified:
- How to define a stress test,
- What approach to use,
- How to define the asset/network and hazard representation for the stress test,
- How to deal with scenarios uncertainties, and
- How to perceive estimated risks and the appropriateness of the test.
The foresight session also simulated a stress test using qualitative approach. This provided a better understanding on what it takes for asset managers to carry out stress tests of their assets and/or networks.
