Resumen
The paper presents a new assessment methodology for owners and operators of transport infrastructure based on the results of the project ?All-Hazard-Guide for Transport Infrastructure? ? being funded by the European Commission DG General Home Affairs under the Prevention, Preparedness and Consequence Management of Terrorism and other Security-related Risks Program (CIPS). It gives an overview on all possible hazards to transport infrastructure. These include (but are not limited to) man-made hazards (intentional and unintentional), extreme weather events and geo-hazards. Based on this, the paper identifies and develops criteria for the identification of important infrastructure associated to threat vulnerability and presents a methodological approach for the assessment of threats and structures, combining the information of the previous knowledge gained on threats and infrastructure characteristics.
