Analysis and assessment of the risk of loss of stability of the car at the radius of the round-off of the Congress to determine the speed

When applying innovations or repeated effective technical solutions of the road sector, it is recommended to use the risk of damage assessment in the project documentation. This gives an opportunity for expert organizations reasonably give a positive conclusion on the project documentation. The method of calculating the risk of harm in the design of the junction to the road, taking into account the basic works of V.V. Stolyarov.A typical example of the study based on the assessment and calculation of the risk of harm is considered. The study is carried out taking into account the Federal law «on technical regulation» and article 15, paragraph 6 of the Federal law «Technical regulations on the safety of buildings and structures» based on the assessment of the risk of failure to achieve the goals and requirements of the Federal law. The probability-theoretical approach, in particular the risk theory, allows to increase safety, comfort and convenience of movement by changing the geometric and transport and operational indicators of roads.The parameters of the curve (radius of curve), the coefficient of adhesion, and the longitudinal slope affect the probability of the car’s stability loss on the radius of the carriageway rounding associated with the car skidding or tilting. This procedure is designed to determine and reduce to the acceptable risk the probability of occurrence of road transport facilities due to imperfections of road conditions (rounding parameters).Technical regulation, risk assessment, damage assessment, risk theory, operations, life cycle, quality management, standards, probability approach, road management.
