Abstract

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. Keywords: mass transit, fire safety concept, evacuation, fire simulation, smoke management, emergency scenario. 1 Approach and objectives The Regulations on the Construction and Operation of Tramways (BOStrab) apply for the construction and operation of Public Commuter Transportation Tunnels in Germany (with the Federal Railway Operation Ordinance – EBO - codes of practice applying for the S-Bahn or Suburban Rail Systems) including any subsequent guidelines, regulations and the generally recognised technological rules such as e.g. DIN and VDV (Association of German Transport Companies) publications. These form the basis for the safety-technical setup of facilities and vehicles but do not contain any emergency scenarios as the basis
