The project AllTraIn aims to develop a comprehensive and structured all-hazard guide for critical transport infrastructures in Europe. The final guide enables owners and operators of transport networks to identify, on the one hand, the relevant threats for his infrastructure and, on the other hand, the types of infrastructures in his network which are susceptible to a specific threat. This approach supports the prevention and preparedness of critical infrastructure by stimulating and supporting risk assessment and developing methodologies for the protection of critical infrastructure.
