The article considers automated traffic flow control systems, their classification and description. Based on the above, it can be argued that traffic control systems have the characteristics of distributed, discrete and non-stationary complex systems used to solve traffic control problems by modern means of information and computer technology. The object of research is to improve traffic control with the help of automated control systems Purpose - analysis of automated traffic management systems With the rapid growth of the car fleet, there is an overload of the street and road network of cities. Even today, the street and road network does not meet the requirements for the organization and safety of road traffic. A survey of traffic flows shows that the road network operates at the capacity limit, and in some places exceeds this limit. The main reason for this transport situation in cities is the mismatch between the level of motorization and the density of the road network. Therefore, to improve, improve traffic control, it is proposed to use automated traffic management systems. But first you need to analyze them in detail. It is noted that the efficiency of the street and road network depends entirely on the effective balanced operation of all its elements.

Introduction. The destruction of the road network has been going on for more than a year. In this regard, there is a need to restore traffic conditions both in settlements and on the public road network. The solution to this problem should be based on the definition of the criterion for the formation of safe and continuous traffic conditions based on the use of modern traffic flow models. Problems. Improving traffic management using transport modeling in the PTV VISSIM software environment. Taking into account such criteria as throughput and delay. Purpose. Development of a model for the distribution of traffic flows on the road network. Research methods. Analytical and experimental with the use of computer simulation modeling. Results. A simulation of vehicle traffic was carried out for three options on the section of the public road of national importance M-06. The first option took into account the existing traffic conditions on the road section, the second option - in case of an obstacle to traffic in the existing conditions, and the third option - with the implementation of the proposed measures. As a result of the modeling, it was found that under existing conditions, the average speed is 50 km/h, the average delay time is 20.46 seconds, but if an obstacle to traffic appears, the average delay time increases and is 156 seconds, and the average speed, respectively, decreases and is 37 km/h. With the implementation of measures, namely the introduction of the distribution of traffic flows along different routes (bypassing the obstacle), the average delay time decreased compared to option two and is 54.67 s, and the average speed increased by 11.64 km/h. Conclusions. As a result of the work performed, it was proved that transport modeling can be used to analyze various options for developing traffic management measures, in particular, solving the issue of congestion on a particular section of the road. Transportation modeling allows simulating the division of traffic flows into alternative routes and evaluating them according to established criteria. As a result, traffic delays and waiting times are reduced, which significantly affects traffic capacity, road safety, and has a positive socio-economic effect.

The main function of road transport is the full and timely satisfaction of the needs of the population in transportation, the acceleration of cargo delivery and the transportation of passengers based on a significant increase in the capacity and quality of the entire transport system, a reduction in the cost price and an increase in labor productivity in transportation. An important place in solving this function belongs to the organization of road traffic, including the rational distribution of traffic flows on the road network, as well as the elimination of conditions that lead to traffic jams and unjustified overruns of vehicles. Having insignificant financial costs in comparison with measures to improve and re-plan the road network, timely measures for the rational organization of traffic make it possible to prevent traffic jams and reduce travel time, and thus increase the productivity of transportation, their cost-effectiveness, which is especially important in the current critical situation with fuel resources of Ukraine. In order to substantiate the optimality criterion for planning road works, it is necessary to take into account the process of traffic flows on the road network under the influence of various types of obstacles, with different degrees of influence arising at different points of the network. When justifying the criterion of optimality, it is necessary to assume that the ultimate goal of the conducted research and proposed measures should be to maintain the efficiency of road network transportation at a certain level, to prevent a decrease in this level in those cases when this decrease can be prevented through rational planning. Thus, operational management of the situation that develops on the road network as a result of the action of a complex of various factors affecting the movement of vehicles is an urgent task and requires the development of scientific foundations and practical methods of its solution.
