Review article

The article presents the results of the analysis of changes in the vehicle safety related to its inadequate controllability. The authors propose using such an indicator of change in the vehicle accident rate as the value of deviation of its movement trajectory from the safe one. There have been obtained results of statistical analysis showing the impact of vehicle displacement during maneuvering on road traffic safety. There is shown the influence of the vehicle design parameters on the movement trajectory change when performing the standard test according to UNECE Regulations no. 140 and GTP no. 8 known as «truncated sinusoidal motion». The given data have made it possible to identify the most significant parameters of the vehicle affecting its active safety, as well as determine the limits of the permissible changes, including those when altering the vehicle design.
