Проблемные вопросы использования спутниковой навигации при оценке состояния факторов «дорога» и «среда» в системе ВАДС

Abstract

The main indicator characterizing the features and specifics of road traffic is the dynamic system «Driver - Car - Road - Environment» (DCRE), in which there is a continuous exchange of information between its components. The level of road traffic safety directly depends on the reliability of the system elements, as well as the specifics of their internal interaction with each other. The article provides an assessment of the factors affecting the reliability of the DCRE system. The authors substantiate the necessity of improving the quality of assessing the key factors of the subsystems «Road» and «Environment» in order to ensure road traffic safety of the motor transport complex. There has been carried out an analysis of the methodology of conducting field surveys in determining the transport and operational qualities of the elements of the «Road» subsystem to ensure the road traffic safety, taking into account the integral components of the DCRE system. The main problems of obtaining high-precision planned coordinates during the operation of road equipment are determined. The possibilities of using RTK (real-time kinematics) and VBS (virtual base station) technologies have been studied in order to improve the methodological apparatus for implementing road safety examinations. The results of the study allow increasing the potential for further work in the field of improving road traffic safety and reducing road traffic accidents` rate, taking into account the road environment features.
