Functional model of road safety for motor transport enterprise with account of high environmental temperatures

Abstract

Introduction. The accident rate in road transport in the summer period of the year in conditions of high ambient temperatures has a steady upward trend. The main reasons for this situation are changes in the condition of drivers and the low efficiency of the climate systems of some vehicles. Motor transport enterprises take into account the conditions of the external environment in their activities and adjust the technology of the transport process. Such environmental conditions are ice, fog, precipitation, low air temperature and others. However, high ambient temperature is not included in such a list. In this regard, the study of the features of the functioning of a motor transport enterprise in conditions of high ambient temperatures and the development on this basis of a functional model for ensuring road safety is an urgent task.The purpose of this work is to improve the safety of road transport on the basis of the development of a functional structure of the road safety service of a motor transport enterprise, taking into account the high ambient temperature.Methods. The work is based on the synthesis of general scientific research methods, which included the provisions of system analysis, as well as the provisions of the theory of transport processes, the technical operation of vehicles.Results. The result of the work was the developed functional model of the road safety service of a motor transport enterprise, according to which the road safety service is endowed with control and administrative functions in relation to the activities of the personnel service, technical service and operation service on issues related to road safety. This model differs from the known ones in that it contains functions for responding to high ambient temperatures. An algorithm has been developed for the functioning of the traffic safety service in conditions of high ambient temperature, which prevents its influence on the increase in the aggressiveness of driving cars and the low efficiency of the climate systems of a part of vehicles. These provisions constitute the scientific novelty of the work.Discussion and conclusion. The practical value of the work lies in the improvement of the tools of the motor transport enterprise, aimed at preventing an increase in the accident rate in conditions of high ambient temperatures.
