ABSTRACT
ABSTRACT: Safe operation of tunnels is very important, because tunnels are specific engineering structures constructed in order to shorten transport routes and improve road safety. Risk analysis for Slovak road tunnels is carried out according technical specification TP 02/2011. Model of risk analysis examines the personal risk of tunnel users and evaluates statistically the expected number of victims per year. For a more detailed examination of the risks of transporting dangerous goods through the tunnel, it is necessary to use a special risk model. A suitable example is a specific risk model DG-QRAM (Dangerous Goods-Quantitative Risk Assessment Model). Tunnel Traffic & Operation Simulator at the University of Žilina in combination with unique software is conducive to research of the possible operating conditions during normal service and model emergency situations. The Simulator manages technological equipment of a virtual twotube highway tunnel interconnected with simulation of vehicle tunnel traffic.
