The goal of this thesis is the analysis of current state of tunnel equipment in Slovenian road tunnels and suggestions for its improvements. From safety point of view an extra thoughtfulness needs to be applied to the matter of driving through road tunnels because of the feeling of constriction while driving through them. Slovenian highway cross consists of two main European transport corridors and represents an important part of Pan-european transport network. That is why European Directive for minimal safety requirements for road tunnels 2004/54/ES came into effect in 2004. Although the status of current tunnel equipment in Slovenian road tunnels is acceptable, it differs among them. For reaching a higher goal in maintaining a satisfactory level of safety in road tunnels, it is necessary to eliminate the differences between types of equipment and its positioning on site. Taken into consideration that human behaviour plays the biggest role in road tunnel safety we also need to consider the effects of type of the vehicle, traffic surroundings and definitely of road infrastructure for safety in road tunnels. Only with unification of different types of equipment and its positioning in tunnels will we achieve the proper safety level in our road tunnels. Often the installation of road tunnel equipment and its positioning is left to the preference of the design engineers and contractors, because there are no guidelines to follow. The first step towards achieving a total unification on this field would be the establishment of technical specifications for traffic management equipment in road tunnels on a national scale
