The increasing complexity of multi-hazard risk assessments, driven by data overload and uncertainties, poses challenges in effectively communicating risks to affected communities and stakeholders. The transportation and mobility sectors include daily commuters, transit traffic, emergency responders and tourists who may be particularly vulnerable to diverse hazards. This vulnerability arises from various cultural and social backgrounds that may lead to different interpretations of warnings and other risk communications. Hazards in mountainous areas include natural, as well as human-induced threats. Bridging the gap between hazard assessment and communication is crucial for resilience and requires transdisciplinary approaches. Traditionally, hazard assessments have focused on geophysical and engineering sciences, emphasizing risk quantification. But what happens after a hazard has been detected and the risk to infrastructure has been assessed? How can such events be effectively communicated during the various stages of natural hazard management – prevention, response and recovery? Cultural factors can influence how people perceive and respond to risks, either mitigating or exacerbating their consequences. To address these challenges, the integration of psycho-social and cross-cultural factors into multi-hazard risk assessment and communication is essential. Such an approach ensures the provision of clear and concise instructions that can overcome automatic human tendencies to respond in a familiar way, which may not always be appropriate in a given situation, and promotes safer behaviour. Other projects have already explored the need for such risk assessments (e.g., IMPACT project) and drafted communication guidelines for multicultural crowds (e.g., LETSCROWD project). Nevertheless, a gap persists in converting risk assessments into practical and actionable communication strategies. Within the EU Horizon project PARATUS, innovative approaches are discussed for multi-hazard assessment and adaptation strategies, particularly within the transportation and mobility sectors. By integrating findings from past studies and ongoing projects, this research highlights best practice examples and actionable recommendations for improving risk communication within transportation and mobility sectors. The ultimate goal is to ensure that risk assessments lead to effective preparedness measures, strengthening resilience against multi-hazard threats.
