Review article

The article substantiates the need to assess the road maintenance level, the identification of risk factors, as well as the necessity to determine the probability of road traffic accidents associated with the geometry of the road environment objects, technical, operational and transport conditions, the state and level of road maintenance. The authors submit the calculation formula of probability of road accident occurrence under certain circumstances on the operated site of the highway. An algorithm for assessing the level of maintenance and the risk factors at automobile roads is proposed. The necessity of applying the high-quality, semi-quantitative and quantitative methods for risk assessment and determination of the road accident risk level is substantiated.
