OPTIMIZATION OF TRAFFIC SIGNAL CONTROL AT ROAD INTERSECTIONS

Abstract

From a functional perspective, intersections are the most complex elements of road networks. This is where paths of traffic from different directions intersect, leading to various maneuvers. This underscores the importance of efficient traffic regulation, especially at intersections, in enhancing safety and improving efficiency. The article investigates the complex relationship between transportation infrastructure and the quality of public life, emphasizing the significance of effective traffic control, particularly at intersections, in enhancing safety and increasing efficiency. The research is aimed at optimizing traffic light management at congested four-way intersections in cities, with the goal of reducing congestion, increasing safety, and improving traffic flow. In most intersections with heavy traffic, traffic movement is regulated by traffic lights, and inefficient settings can lead to unjustified long waiting periods and increased overall traffic delays. For simulation modeling of traffic conditions at this intersection, PTV Vissim software was used. Observations of traffic flows, their distribution by direction, and parameters of traffic light regulation were used as input data for intersection modeling. The results of the modeling identified various approaches to optimizing traffic light management, including adjusting cycle times and considering passenger flows, with a particular emphasis on adaptive systems that respond to real-time traffic parameters. The study identifies challenges such as variable traffic flow and proposes solutions such as extending green phases and introducing pedestrian phases. It concludes by emphasizing the importance of collecting and interpreting dynamic traffic movement parameters for effective traffic light regulation, particularly in the implementation of automated traffic management systems.
