Numerous people, dead and injured as a result of road accidents at the tunnel-type interchanges proves that the measures, taken for prevention of emergency situations in tunnels are insufficient. At the same time, various monitoring systems are installed at such facilities, being not connected among themselves. So, they cannot reduce, but can even increase the consequences severity in case of emergency situation because of the inconsistency of joint operation of the automated control systems for safety and life support at the road interchanges of tunnel type. The analysis of possible types of threats for the road interchanges of tunnel type allows to conclude, that some adequate measures for ensuring their safety can be taken only with the use of automated systems of remote monitoring of the facilities condition, modern communication systems, organization of the proper training of specialists for complex safety of facilities as well as advanced trainings of designers in this sphere. The main causes of emergency situations at the road tunnel-type interchanges are considered to achieve this goal. The causes of insufficient efficiency of the existing technologies and technical means of ensuring complex safety of tunnels are also analyzed. The technology of complex safety of the road tunnel-type interchanges is developed and approved on the basis of the carried-out analysis and with the use of methods of systems analysis and the theory of experiment. Experimental studies were carried with the use of the theory of experiment and the use of certified measuring instruments. It was proved scientifically and confirmed experimentally, that the offered technology of complex safety of the road interchanges of tunnel type allows to reduce risk of emergency situations and people’s death in tunnels by more than 50%.
