The Bridge project, funded with 13 Mio Euro under the EU FP7 Security Theme, is one amongst several international efforts to support professionals and volunteers in mobilising information and resources for disaster response. Coordinated by SINTEF Norway, it brings together 14 academic and industrial organisations, including software developers (Saab, Thales), practitioners (Rakos Norway), and social scientists. Taking an ethnographically informed, iterative and experimental user-centred design approach, the team will develop socio-technical systems for multi-agency, cross-border disaster response that push the state of the art in information technology (IT) and professional and public practice. Fieldwork and experimental design scenarios focus on multi-modal transport hubs such as the Madrid subway and the Øresund bridge between Copenhagen (airport) and the Swedish city of Malmö.
