Emergency scenarios for tunnels and underground stations in public transport

The phase from the design to the operation of tunnels for railbound public transportation systems proves to be extremely protracted in practice. This is due to the necessary approval procedures and extremely different appraisals pertaining to safety for instance. The design phase can be appreciably reduced if a standard emergency scenario is presented, for which a suitable safety concept must be available. Experts then decide on the case of fire as a standard scenario from possible emergency scenarios by dint of which the required safety considerations are to be carried out for new structures so that a standard basis for planning is created in Germany. The principal approach is shown for example for designing underground stations so that persons can rescue themselves and be rescued through establishing short evacuation periods and long smoke proliferation periods.
