Abstract: The movement of single and group cars in traffic flows was investigated during the work. These studies are used to calculate the vehicle delay time during maneuvers through crossings and adjacencies at the same level. On the basis of the data obtained, the technical and economic discussion of the cross-sectional or adjoining parameters under consideration can be made.

In the course of the study, examination will be conducted on the influence of intensity, velocity and traffic flow on the distribution intervals between cars and a graph of this effect for different traffic intensities is to be constructed. On the basis of the provided charts, the dependence of the free interval, necessary for maneuvering, on the traffic flow intensity is described. Using this dependence, you can figure out the number of cars that can be transported continuously.

Knowing the traffic flow, its intensity and the distribution of free intervals between cars and groups of vehicles, the lag time of cars that are waiting for the ability to maneuver as well as their quantity can be calculated with the help of the proposed method.
