Probabilistic Risk Assessment and Optimization of Road Tunnels
Original language description
Probabilistic methods of risk optimization are applied to identify the most effective arrangements of road tunnels. The total consequences of alternative tunnel arrangements are assessed using Bayesian networks supplemented by decision and utility nodes.It is shown that the probabilistic optimization based on the comparison of societal and economic consequences may provide valuable information enabling a rational decision concerning effective safety measures of road tunnels. A general procedure is illustrated by the optimization of a number of escape routes. It appears, however, that the discount rate and specified life time of a tunnel affect the total consequences and the optimum arrangements of the tunnels more significantly than the number of escape routes. Further investigation of relevant input data including societal and economic consequences of various hazard scenarios is needed.

Pravděpodobnostní odhad a optimalizace rizik silničních tunelů
Czech description
Pravděpodobnostní modely a optimalizace rizik se využívají pro stanovení nejvhodnějšího uspořádání silničních tunelů. Celkové následky alternativních uspořádání se hodnotí s využitím Bayesovských sítí. Obecná metodika se ilustruje na příkladu optimalizace počtu únikových cest.
