This paper deals with possibilities to update existing road tunnels in order to fulfill up to date requirements regarding structural fire protection. Besides the upgrading of tunnels with structural fire protection systems (like e.g. fire protection sheets) there is also the possibility of numerical investigations. In research projects carried out on behalf of the Federal Highway Research Institute (BASt) numerical investigations for the proof of sufficient structural fire protection have been done for common road tunnel types. Additionally the influence of different fire loads and fire durations on the bearing capacity of the structures have been investigate existing tunnels regarding structural fire protection. The research results have also been the basis for a current update of national standards for tunnel construction.
Although the EU has implemented some legislation on the security of transport infrastructure in Europe (i.e. EPCIP Directive 2008/114/), the security of transport networks up to date remains a national prerogative. While research has been conducted on a European scale, operative measures are implemented only on the national level. This paper argues for an Europeanisation of transport security, focussing on practicable recommendations for achieving this goal. Additionally, the divergence between a nationally shaped risk perception and the cross-boundary nature of security threats is discussed and possible strategies to overcome this problem are outlined. Furthermore, the paper aims at fostering the debate between (transport) security stakeholders in the EU Member States and presenting incentives and arguments for a shift from a national to a European security rationale.
