Klochan A. Polarimetric Method for Positioning and Monitoring in the Road Transport

The dissertation work is devoted to the solution of an important scientific and practical task of increasing the efficiency of positioning and monitoring on road transport in order to improve traffic safety, by developing a polarimetric method for positioning and monitoring road transport, which, unlike most existing ones, allows determining not only their positional, but also orientational position. The purpose of the dissertation is to develop and apply a polarimetric method of positioning and monitoring motor vehicles to increase road safety when transporting goods and passengers. The object of the study is the processes of determining the relative positional and orientational position of motor vehicles. The subject of research are methods and models for determining the positional and orientational position of motor vehicles. The scientific novelty of the obtained results lies in solving a scientific and practical task, which is related to increasing the efficiency of positioning and monitoring on road transport by determining the relative positional and orientational position of motor vehicles using the developed polarimetric method. At the same time, for the first time: - a polarimetric method of positioning on motor vehicles is proposed, which, unlike most existing methods, allows determining not only the relative position, but also the relative orientation of motor vehicles; improved: - a polarimetric method of determining the direction of the source of linearly polarized radiation by using a modulator in the radiation unit, which allows to reduce the number of measurement channels and reduce the measurement error of vehicle movement parameters caused by the propagation medium; - methods of assessing the reliability of information of parallel information backup systems by studying the four-parameter state graph of the system for determining the controlled parameter, which allows you to determine the probabilities of correctly determining the presence and absence of a controlled event; acquired further development: - a system of criteria and indicators for assessing the effectiveness of positioning and monitoring in road transport, by considering the control scheme of the studied parameter, based on which it is shown that the effectiveness of positioning and monitoring depends on the effectiveness of the vehicle traffic management system. The practical significance of the obtained results lies in the development of a polarimetric method for determining the positional and orientational parameters of the relative position of motor vehicles, as well as in the improvement of methods of assessing the reliability of information of parallel information backup systems, which allows determining the probability of correctly determining the presence and absence of a controlled event. The main scientific and practical results of the dissertation were implemented in the educational process of the Department of Information and Analytical Activities and Information Security of the National Transport University of the Ministry of Education and Culture of Ukraine, a patent was obtained for the useful model "Polarimetric method of determining the direction of the source of polarized optical radiation" and a certificate of copyright registration for the computer program.
