The document summarizes the RIMAROCC project, which aims to develop a common risk analysis and management method for roads in Europe with regard to climate change. It describes the context, objectives, work packages and steps of the proposed RIMAROCC method, which involves identifying risks and vulnerabilities, analyzing risks, evaluating risks, mitigating risks, and monitoring outcomes. Key steps include establishing the context, identifying risks and vulnerabilities, analyzing risks, evaluating risks both qualitatively and quantitatively, mitigating risks through options appraisal and action planning, and monitoring results.
