Introduction. One of the reasons for ordering the reconstruction of a road or part of it is the deterioration of the safety of traffic flows, as a result of which the number of victims and material losses in road traffic accidents (traffic accidents) increases. Interchanges at the same level have the greatest influence on the traffic intensity on the highway, as traffic flows are redistributed at them. Depending on the intensity of traffic on them, the maximum possible intensity of traffic on the road section as a whole will be determined.
Problem statement. The analysis of determining the need for road reconstruction in accordance with the regulations established the need to justify and clarify traffic intensity data, according to which it is necessary to assign a road reconstruction and determine the period of effective operation of the road, for this it is necessary to conduct a number of traffic flow studies.
Purpose. The purpose of the article is to study the patterns of traffic flows at traffic junctions at the same level and the relationship of the characteristics of traffic flows to each other.
The methodology of an experimental study of traffic flow patterns at traffic intersections at one level consists in surveying the real conditions of traffic flows, namely, the traffic intervals between cars on the sections of the race between the intersections with a traffic intensity of 300 to 600 vehicles per hour per lane, to further establish the dependence of the availability and number of free movement intervals in the traffic flow.
Results. The article presents an algorithm for determining the maximum possible intensity of traffic on a highway on its separate sections between adjacent intersections and junctions, taking into account the real distribution of traffic intensity on them, which makes it possible to predict the effectiveness of the functioning of a separate section of the highway and to make decisions about complete or selective reconstruction of the highway or the reconstruction of the traffic junction.
Conclusions. The main condition for the effective functioning of single-level traffic junctions and the highway as a whole has been established, which is the presence of free traffic intervals on the main road, which makes it possible to perform right and left turn maneuvers when passing through single-level traffic junctions without traffic complications.
