“…The coefficient of adhesion of tires to the road surface must be taken into account and determined for the following types of road accidents and road sections: a collision when overtaking on a convex (concave) curve, a collision in the plan (with an exit to the side of the oncoming traffic direction), a collision of oncoming vehicles on a horizontal road section, a vehicle skid caused by the destruction of suspension elements of one of the wheels and/or the destruction of the wheel tire, a collision of vehicles at an unregulated intersection [4,5].…”

Road and weather conditions have a significant impact on the occurrence of road accidents and their development as events. According to these circumstances, the system “Driver – Car – Road – Environment” identifies certain types of expertise that are engaged in determining the presence and magnitude of the parameters of the road environment that affect the development of the road transport situation. When conducting relevant investigations, the experts calculate the speed and length of the stopping distance of the vehicle, using coefficients that determine the impact of road conditions on the road traffic situation under study. One of these important indicators is the coefficient of adhesion of car tires to the road surface. Due to the lack of technical capability to experimentally determine the coefficient of adhesion at the place of an accident, many experts are forced to use values from the reference literature. This study is devoted to checking the agreement of reference values of this indicator with actual values that correspond to the conditions of driving on Russian roads. To solve this problem, full-scale measurements were made of the coefficient of adhesion of tires with a coating on more than 2000 km of roads in different regions of Russia (with different climatic and topographic conditions) and the results of field research were analyzed.
