Abstract

Purposeful management of improving the efficiency and objectivity of expert studies of road traffic accidents, the use of modern tools for collecting, processing, storing and transmitting data from the accident scene, computer equipment allows us to achieve a higher level of productivity of auto-technical experts. Establishing the circumstances and the mechanism of interaction of participants in the movement during the examination of accidents is characterized by the multifactorial nature of the models and the nonlinearity of the connections between the input and output parameters. Therefore, it is important to realistic simulation of these processes, taking into account the maximum number of influence factors, which will not only minimize the time and cost of expert research, but also increase their objectivity.The article analyzes the current state and trends in the development of auto technical expertise of road accidents, addresses the issues of calculating errors and processing measurement results during road crash examinations using the example of determining the rotation parameters and the stopping distance of a car. In the simulation, the boundaries of the change in the calculation error of the stopping distance of vehicles and the deviation of the vehicle in the direction perpendicular to the initial direction of motion from the coefficient of adhesion of wheels to the road are determined.The conclusion presents the results of the analysis of the problems of improving the quality of the investigation and conducting autotechnical examinations of accidents.
