IMPROVEMENT OF THE SYSTEM FOR ACCOUNTING OF PARAMETERS DURING CONSTRUCTION OF MOTOR ROADS

In the article, a necessity to improve the system for accounting of parameters for additional factors of technical condition of vehicles and road environment facilities allowed for during design and construction of motor roads is substantiated. A procedure for the determination of circumstances and causes of road accidents, taking into account transport, technical and operating conditions, has been developed. An improved algorithm of expert examination with the application of a non-destructive method with use of diagnostic equipment of dynamic impact is offered. The accounting system includes an algorithm of expert examination of road accidents which provides parametric characteristics of objects and conditions for their existence to ensure procedure functioning. Criteria to identify "weak"sections of motor roads are proposed. A model for the implementation of expert examination taking into account parameters of the subsystem "Vehicle–Road" is proposed. A possibility to determine the risk of road accidents, "weak" sections of operated motor roads, development of an automated data base on motor roads, application of research results in expert opinions upon analysis and reconstruction of road accidents is substantiated

Influence of regional features of psycho- emotional state of the Russian society on road accidents severity

The article considers issues of assessment of the relation between road accidents severity and psychoemotional state of Russian society. In the context of the hypothesis about the significant impact of people’s awareness of the value of life on their ordinary behavior, four subtasks were solved. Firstly, the difference in road accidents severity between all road accidents and road accidents that happened in alcohol intoxication state was established. Secondly, indicators of the psychoemotional state of people from different Russian regions were identified. Thirdly, dependencies «Road accidents severity = f(Psychoemotional state of people from Russian region)» for two cases - «All road accidents» and «Road accidents that happened in alcohol intoxication state» were defined. Finally, it was found that degree of impact of alcohol intoxication on road accidents severity depends on the psychoemotional state of people from different Russian regions. Produced results can be used in the development of regional programs of road safety management taking into account features of the psychoemotional background in different subjects of Russia

Estimation of the reaction time of the driver of a two-wheeled vehicle in case of danger

The author's team analyzed a bicycle as a two-wheeled vehicle. (TWV) The purpose of the study was to estimate the parameters affecting the reaction time of the cyclist. Depending on the type of brake system, the mass of the two-wheeled vehicle and the cyclist, the speed, and the bicycle designs graphs were built, and their analysis was carried out. Based on the test results, factors affecting the cyclist reaction time in case of danger were disclosed

Methods of optimization of motor transportation processes

A scientific approach to the methods of technical support, economic and organizational management, planning and control of the operation of cars often dictates the need to make a decision, not one at a time, but several efficiency measures. The article outlines the approach to the solution of multicriteria transportation problems based on the methods of regionalization according to the principle of observing the hierarchical correlation of probabilities of possible states of the external environment
