 Abstract. The issue of safety and traffic potential on public motorways often arises due to large-sized vehicles such as buses, agricultural machinery, and road articulated vehicles stopping on the roadsides. This is caused by the number of logistic transportations between the territorial subjects of the Russian Federation, which has increased recently due to the increase in the number of warehouses and, as a consequence, the increase in the number of heavy and full-size vehicles. The problem is especially acute at high traffic intensity, when four vehicles are simultaneously located on a two-lane road in one transverse profile. In this article the authors consider the safety analysis of cross profile elements of a motor road on safety maintenance of road traffic at a collision of a passenger car on the car stopped on the roadside with simultaneous separation on a two-lane motor road from the position of the risk theory. This approach to the risk calculation methodology is developed within the framework of the scientific direction «Design, construction and operation of motorways under the condition of ensuring traffic safety taking into account the risk theory». The purpose of the calculation is to check the safe stopping possibility of large-tonnage vehicles on roadsides of II, III and IV categories on the basis of
risk-oriented approach according to geometric elements normative dimensions of the public roads cross profile.
