Safety in tunnels on motor- and expressways
Both the probability of accidents occurring and the probability of being injured is lower in tunnels than on open stretches of roads. However, if an accident does happen in a tunnel, the risk of being killed is significantly higher than on open stretches of motorways. In a tunnel the risk of being killed in a traffic accident is 1.5 times the risk of open stretches on motorways. In tunnels with bi-directional traffic the probability of being killed in a traffic accident is 1.4 times as high as in tunnels with unidirectional traffic. Both in tunnels with bi-directional traffic and in tunnels with unidirectional traffic the highest accident rates occur in the portal area. Based on the results of this analysis various measures aimed at raising traffic safety in tunnels are recommended.
