In the EU, road accidents are in the top three causes of deaths and hospitalizations . WHO finds it crucial to discourage speeding, because it is a main cause of road accidents. The Fellow’s research in the psychology of human factors engineering shows that people underestimate the risks of accidents from speeding and overestimate how much time is saved through speeding. Public campaigns have typically not yet sought to correct these misunderstandings but rather have focused on emotional fear-appeals to reduce speeding. The Supervisor’s work on risk communication provides a systematic method for correcting such decision-relevant beliefs, which has been successfully applied to a variety of contexts, but not to the design of dashboard tools. We take the novel approach of combining the Fellow’s and Supervisor’s fields to design dashboard tools and public campaigns that discourage intentions to speed by correcting drivers’ misunderstandings of the risks and benefits of speeding. This project will benefit from Fellow's experience in leading projects on informing driver perceptions with dashboard tools, and her ongoing partnerships with the car industry and governmental agencies. The project will lead to knowledge transfer between the Fellow’s Swedish Transportation Institute, partners at Volvo Cars and government agencies as well as the Supervisor’s Centre for Decision Research and the associated Institute for Transport Studies at the University of Leeds (UK). The project will boost the Fellow’s academic career progression, as she aims to become a world-leading expert in evidence-based interventions that improve driver safety and save drivers’ lives.
