Abstract
Article 13 of the EU Directive on minimum safety requirements for tunnels in the Trans-European Road Network states that a risk analysis, where necessary, shall be carried out. In the Netherlands, the risk of decease for road users in a tunnel (internal risk) is calculated with a model for quantitative risk analysis, which is called “QRA-tunnels”. QRA-tunnels is not suitable to explicitly calculate the risk in tunnels with additional ramps. The model does not foresee input for additional ramps. In this paper a method is presented enabling the explicit calculation of the risk in a tunnel with additional ramps. This method to Calculate Additional Ramps Explicitly (CARE) has been applied to the Churchill tunnel, one of the alternatives to connect the highway A4 with the A44 in the vicinity of the city of Leiden in the Netherlands. The calculations performed for the Churchill tunnel serve to illustrate the method
