Abstract. This study is the result of collaboration between specialists of the Ural State Forest Engineering University and the Nosov Magnitogorsk State Technical University. Having compared the results of their own independently conducted studies, the authors came to the conclusion that ensuring road safety at controlled intersections in medium and large cities has a common scientific and methodological basis. Existing methods for calculating the duration of traffic light control cycles are aimed at ensuring maximum throughput in all directions of traffic at the intersection. Experts also assume that the main thing in determining the duration of the traffic light control cycle is to ensure road safety. However, in modern scientific literature there are few works devoted to modeling the movement of vehicles with the condition of accident-free passage through the intersection.

The purpose of this study is to develop a methodological toolkit for ensuring road safety at regulated intersections in the presence of turning flows by improving the organization of vehicle traffic. The main results that have scientific novelty are:

– factors influencing the provision of road safety at intersections in the presence of turning flows;

– a mathematical model of vehicle traffic at the intersection, determining the distance between cars, ensuring safety;

– a methodology for ensuring road safety at regulated intersections in the presence of turning flows, taking into account the obtained mathematical model of vehicle traffic.

The article is written based on the materials of the dissertation abstract by Gasilova O.S.3, as well as the report on research work on monitoring road traffic on the road network within the boundaries of the Magnitogorsk urban district4. In the course of the research, the authors improved the methodology for visualizing the results of recording the intensity of traffic flow on the city road network, experimentally confirmed the effect of traffic flow deceleration on the duration of the main cycles of cars overcoming the intersection, structured the mathematical model of vehicle movement at the intersection, which provides the possibility of automating calculations.

Further research is expected to be conducted in the direction of developing a methodology for ensuring the safety of motor vehicle traffic on a road network with controlled intersections, as well as the development of intelligent traffic management systems.

Key words: road safety, controlled intersection, traffic management, minimum safe distance, traffic accident.
