Abstract
Modern developed societies are heavily dependent Oil urban infrastructures like road, railway, gas, electricity, and water supply. The breakdown of one of such critical infrastructures may cause serious consequences for the safety of the citizens. Managing the safety and Security of these infrastructures taking into account prevention and preparedness, crisis interventions and restoring normal conditions using optimised and risk based approaches are important. Five years ago, a project oil Proactive Crisis Management of Urban Infrastructure was submitted to the European Union under the COST programme. As a consequence, the COST C19 Action was created. This paper presents the main Conclusions and lessons learned from the project.
