INTERACTION OF VEHICLES AT A SIGNALIZED INTERSECTION WHEN THE GREEN LIGHT IS ACTIVA

Abstract. The organization and efficiency of traffic signal control at intersections are key factors influencing the capacity and congestion levels of the urban road network. Improper traffic signal operations can cause additional delays, reduce traffic flow efficiency, and increase the risk of accidents. The relevance of this study lies in examining the impact of vehicle start characteristics on the dynamics of movement through signalized intersections and assessing their effect on traffic flow optimization. This paper analyzes the movement of two vehicles traveling sequentially through a signalized intersection when the green light is activated. The primary focus is on studying parameters such as the ratio of distances traveled by the vehicles, the ratio of their speeds, the start delay of the second vehicle relative to the first, and the variation of these indicators during movement. Evaluating the interrelation of these parameters allows for assessing the optimality of traffic flow and its safety level.
