statistical period (2010-2013). Then, according to the frequency of accidents in
atmospheric conditions and the communication axis were determined. classification
and hazardous points . In rainy weather, the frequency of accidents was 16%, in
foggy weather, the frequency of accidental accidents was 11%, in the conditions of
airy weather, the frequency of accidents% 9% and in all atmospheric conditions, the
frequency of accidents was 493 and the Kohin-loshan axis has the maximum
