In addition to Work Package 5 – Demonstration projects, and Work Package 6 – Project Management, ICARUS consists of 4 technical Work Packages:

Work Packages

Work Package 1

Impacts and Operational Risks

Working Package 1 collates and creates new knowledge on climate risks to European roads. It includes rating consequences of damage for quantification and evaluation of the impact of each damaged asset by compilating and studying the impact pathways of climate change on the road and the transport system.

This Work Package aims to provide a context for understating the resilience of road on terms of Loss of Service indicators to climate events, while considering both direct and indirect damages and effects as well as incremental and extreme events.

Work Package 2

Adaptation and resilience measures to achieve minimum viable service levels

Working Package 2 identifies effective adaptation measures to increase road network resilience and to maintain minimum viable service levels. Guidance will be given on how minimum viable service levels can be established and used in practice. There will be a specific focus on the effectiveness of nature-based solutions. Finally, this Working Package will provide guidance on how to implement the measures in the various processes within an NRA.

Work Package 3

Appraisal Methodologies, Benefit and Costs

Work Package 3 runs over 18 months and will be implemented with Ramboll as lead, together with WP Partners RDS, Deltares and Maple. WP3 has a special focus on Nature-Based Solutions and whole-life costs. The objectives of WP3 are as follows:

  • To provide appraisal methodologies supporting the business case for building climate change resilience measures within the road infrastructure sector.
  • To provide guidance for the holistic valuation of climate adaptation measures as part of an integrated CBA, with focus on benefits and co-benefits.

WP3 will give an overview of the State of the Art and current State of Practice regarding cost-benefit analysis of climate resilience and road infrastructure, founded both in the scientific literature and in the numerous examples of initiatives already practiced throughout Europe. It will be an evidence-based approach that will identify, collect, and compare best-practice cases, standards, and guidelines for climate resilience, with a particular emphasis on synthesizing previous research.

Work Package 4

Case studies, dissemination and implementation

Work Package 2 brings together the results from work packages 1 – 3 to put innovation into practice. It will determine the audience for the outputs of the project and establish the most effective means to engage them and transfer knowledge. The work package will draw together the information on case studies and Nature Based Solutions developed in work packages 1, 2 and 3 and present them in a way that they will be a valuable lesson to NRAs across Europe most effectively. Finally, it will develop and deliver training materials and training itself to ensure that the outputs of this project are implemented within European NRAs.

Work Package 5

Demonstrator Projects

Work Package 5 will develop the terms of reference for three Demonstrator Projects which will facilitate real life application of the tools developed in ICARUS WP1, 2 and 3. The demonstrators will be spread across various European climate zones. The demonstrators will also cover all life cycle phases for integrating climate change adaptation (design, procurement, construction, maintenance, and renovation / renewal). The Demonstrator Projects will be developed in consultation with the PEB and CEDR, via identified Champions.

Funding Partner


The CEDR Transnational Research Programme (TRP) operates through a series of annual transnational calls on topics that address the needs of European road authorities.

The Aim of the Climate Change Resilience programme to undertake research on integrating climate change into decision-making processes and implementing existing research into practice.

Roads and climate change

Call 2021 climate change resilience

The results will help to avoid and minimize the disruptive impacts of increasingly extreme weather events on the existing road infrastructure.
