Optimization of Tunnel Ventilation and Tunnel Safety Equipment

Safety design for road and rail tunnels is experiencing an increasing stress arising fromtwo partly contradictory requirements, enhanced safety and life-cycle cost optimization. A varietyof useful safety measures, facilities and equipment can contribute increasing safety but can have asignificant cost, in terms of both CAPEX and OPEX. An optimum balance between costs andbenefits is called for. Several techniques and tools support the safety engineer’s optimization effort.This paper focusses on Quantitative Risk Analysis (QRA) and advanced simulation, which cangreatly contribute to optimum design, particularly with respect to ventilation and safety equipment.
