Abstract

Ensuring road safety is a top priority in Ukraine. On the world map of the number of people who died in an accident in 2017, our country has an average, and among the European countries, one of the highest - 13.5 per 100 thousand people. An important issue of ensuring road safety is the definition of conditions for the use of vehicles. The main criteria in determining the group of operating conditions is the relative rate of change in vehicle speed, of the car and the noise acceleration factor of the car. In the article, based on the energy approach to the analysis of traffic flow kinematics and traffic safety, a method of estimating deterministic characteristics is proposed. This method takes into account the power of the traffic flow and its gradients over time and distance traveled. The results of theoretical investigations of the power characteristics of the KrAZ-6322 vehicle are presented, forming a unified evaluation system for obtaining information on the processes of formation of the level of traffic safety. The energy characteristics of traffic flow safety allow not only performing estimation calculations. First and foremost, they carry comprehensive information on the parameters of the accident, depending on the conditions of operation, which allows objectively reproducing the process of formation of traffic safety, indicating ways to reduce the number of places of concentration of traffic accidents, their numbers and severity. In the long term, it is necessary to develop a method of joint application of the deterministic system for assessing the level of road safety by the energy characteristics of the traffic flow with probabilistic models of quantitative characteristics of the accident.
