Abstract. The formation of traffic congestion remains a significant problem in the organization of road traffic in cities and is a serious challenge for engineering and science. Domestic and foreign practical experience, as well as scientific research have shown that the most rational approach to solve this problem is the use of intelligent transport systems, the subsystem of which, in terms of traffic management on the road network of cities, are automated traffic management systems. However, in the case of implementation of traffic flow control in the automated mode on the basis of values of the number of passing vehicles, there is uncertainty: the value of the traffic flow intensity can be equal to or close to zero both in the case of traffic congestion and in the case of complete absence of the vehicle. In modern foreign scientific research it is offered to solve this situation by means of comparison of data of intensity of traffic flow with its concentration in time (lane occupancy). Unfortunately, this process is not fully for understanding. Therefore, the purpose of this article is to improve the previously developed by the authors of the model of the influence of lane occupancy on the intensity of traffic flow, taking into account a wider range of experimental data. Achieving this goal required theoretical studies, which were based on the theory of transport flows, the theory of pulses, mathematical modeling. To confirm the results of theoretical studies, experimental studies were conducted, which were based on the theory of experimental planning, mathematical statistics. The initial data for the experiment were collected and processed with the help of software and equipment STATISTICA 10, SPECTRUM 2.0, Traficam, etc.in the end, the initial model of the influence of band occupation on the intensity of traffic flow was corrected. The scientific novelty of the research results lies in the fact that the corrected model reliably displays the physical meaning of the process of changing the intensity of traffic under the influence of the concentration of traffic flow in time, taking into account the different modes of operation of the adjustable cross-section. the obtained results can be used to improve the algo-rhythms of controlled intersections in the automated traffic management systems, calibration of simulation models of traffic flow movement, operational control of traffic flow.
