IMPACT OF ROAD AND INTELLIGENT TRANSPORTATION INFRASTRUCTURE ON TRAFFIC SAFETY: NEW APPROACHES TO RISK CLASSIFICATION

The article presents a new approach to the classification and assessment of risks on suburban highways based on the multidimensional analysis of the Driver-Automobile-Road-Environment (DARS) system. The methodology of risk assessment using a comprehensive index (CRI), which takes into account the degree of impact of factors, types of interaction between system elements and components of the transportation system, is developed. Special attention is paid to the role of road infrastructure and the capabilities of intelligent transportation systems (ITS) in risk management. Innovative solutions to improve traffic safety are proposed, including the use of “smart” pavements, vehicular communication systems (V2X) and “road digital twin” technologies. It is shown that the complex introduction of modern technologies can reduce the number of traffic accidents by 20-30% within 5-10 years. The analysis of socioeconomic effects from the implementation of the proposed solutions is presented.
