The subject of the study is the change in the average delays of vehicles at regulated intersections with adaptive control when using sensors "presence". The goal is to develop a method by which it is possible to determine the parameters of the traffic light cycle that provide the greatest efficiency of the traffic light object by reducing the average delays at the intersection. Research objectives: analysis of existing methods for determining the parameters of the traffic light cycle - the duration of the traffic light cycle and its main measures; determination of the dependence of changes in the average delay of vehicles at an unregulated intersection depending on the intensity of traffic on a secondary road; determination of the dependence of changes in average delays at the intersection depending on the duration of the main cycle for a secondary road at various values of intensity with adaptive control. The following results are received. Dependencies are obtained that make it possible to determine the changes in the average delays at the intersection from the duration of the main cycle for a secondary road with existing parameters and proposed parameters determined by the proposed methodology. The dependences of the change in the average delays at the intersection with a change in the duration of the main cycle for the secondary direction, as well as when the intensity of the traffic flow along the secondary road both with existing parameters and those proposed are obtained. Conclusions. The question of minimizing the delays of vehicles at intersections directly affects the efficiency of the transport network. Therefore, it is necessary to look for different options to reduce the average delays at intersections. One way is the use of adaptive control and the use of sensors "presence". Using the proposed methodology and the obtained models, it is possible to determine the duration of the main cycle in the traffic light cycle for a secondary road. This will minimize the average delays at the intersection, which in turn will increase the efficiency of its functioningDownloads
