Introduction. As you know, mountain areas in their development to some extent lag behind the plains. In fact, any undertaking in the highlands of an economic, social, agricultural or other nature aspects begins with the solution of the transport problem. At present, transport projects are subject to the requirements of high intelligence with innovative developments, safety, awareness of the road environment, comfort, environmental friendliness and quietness. If on the plain when choosing the directions of the road there are practically no restrictions than in mountain conditions the laying of the road faces a lot of difficulties of relief character, requiring the use of maximum slopes and small radii on the curves, as well as a certain geographical location of the gorge, which sometimes is frontal from the required direction of the road. On the slopes of these gorges to some extent surface exogenous phenomena were developed in the form of landslides, landslides, mudflows, avalanche-glacial and ice formations, the processes of collapse which complicate the design, construction and operation of the transport artery. Creating a transport project in such difficult mountain conditions is extremely difficult, but important. The urgency of this problem increases the need to present to the promising transport communications intelligence that is not yet sufficiently formed for mountain roads. The purpose of the work is to monitor the operation of mountain roads by accident on the example of the Transcaucasian highway (Transcam) and the application of existing rules and regulations in the search and design. Method of research. The research was conducted by the method of analysis of existing design developments, monitoring of mountain roads operation and accident rate. Research result. Complicated conditions of the survey and design of roads in mountainous conditions forced project implementers because of relief conditions to apply the maximum and the maximum allowable longitudinal slope, small radius curves, respectively, that during operation creates a hazardous traffic condition and leads to road accidents.
