Multiagent Control

A test bed for multiagent control systems in road traffic management is presented. As the complexity of traffic control on a network grows, it becomes more difficult to coordinate the actions of the large number of heterogeneous traffic management instruments that are available in the network. One way of handling this complexity is to divide the coordination problem into smaller coherent subproblems that can be solved with a minimum of interaction. Multiagent systems can aid in the distribution of the problem (over the various agents that compose the multiagent system) and facilitate the coordination of the activities of these agents when required. In the literature, no consensus exists about the best configuration of the traffic-managing multiagent system and how the activities of the agents that compose the multiagent system should be coordinated. The decomposition of a problem into various subproblems is an active field of research in the world of distributed artificial intelligence. A survey of approaches reported in the literature is presented. Subsequently, both the test bed and the modules that compose it are introduced. Finally, an application is presented that illustrates some of the research the test bed has made possible.

Information And Computer Technology

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.

Traffic Control System

Modern road traffic control systems become more complex with each year due to the growing number of cars, demand for more optimized road network designs, and desire to decrease road traffic delays at the intersections during rush hours because of the constantly growing metropolitan area and hence the need of moving farther away across the city. Therefore, a need is very much relevant nowadays for technologies, which can help build more optimal and intelligent road traffic control systems, which in turn will help optimize already existing road network designs. With the help of computer modeling software, it is possible to recreate already existing segments of road network, and by implementing control logic, it is possible to observe how control system and road traffic would react to various changes. This paper looks at how computer modeling software (namely SUMO) can help with the validation of road traffic control system changes without the risks of road traffic accidents caused by manipulation of real control systems.

The article analyzes the introduction of the European experience for ensuring road safety on the highways of Ukraine. The conclusion is made on the feasibility of introducing such an experience in Ukraine. The basic directions, which should promote the creation of a safe, reliable, stable, stable, and regulated system of road safety in modern living conditions are determined. Analysis of the best European practices for the introduction of modern automated road traffic control systems based on the achievements of European colleagues will significantly improve the situation in the field of road safety. The introduction of innovative management technologies, including road traffic, will provide the necessary sustainable development of the economy and society as a whole. Prevention as the main and priority direction of positive European experience such as clarification in mass media, distribution of information brochures, promotion of law-abiding drivers, and conducting of explanatory work with youth will allow reducing the number of offenses on the roads of Ukraine. Because safe roads, this is primarily the conscious, but safe behavior of every participant in the traffic, regardless of age, sex or property status. Already the first work on the part of state authorities is the approval of the government program “Strategy for Enhancing the Level of Road Safety in Ukraine until 2020″, which was approved by the Cabinet of Ministers of Ukraine Resolution No. 481-r of June 14, 2017. The return of the Tricam radar from October 16, 2018, to fix violations of the high-speed regime will improve the control over compliance with traffic rules, which will result from increased security and a reduction in the number of administrative offenses on the roads of Ukraine. The most effective measure aimed at ensuring road safety is the creation of a Safe City project in cities of Ukraine, which is to introduce video surveillance systems to enhance the safety of road users, control the operation of public utilities, and manage city traffic. Already in some cities, electronic surveillance systems are in place that recognizes the driver’s face and vehicle numbers. Cooperation with operational units of the Ministry of Internal Affairs, Security Service, and Ministry of Emergencies has been established. Keywords: safety, road traffic, transport, traffic accident, European experience, speed recorders, automated control systems, analytical and legal support.

This article discusses the question of the possibility of improving the roll stability of partially filled tank vehicles while braking. We consider the dangers associated with partially filled tank vehicles. We give examples of the severe consequences of road traffic accidents that have occurred with tank vehicles carrying dangerous goods. We conducted an analysis of the dynamic processes of fluid flow in the tank and their influence on the basic parameters of the stability of vehicle. When transporting a partially filled tank due to the comparability of the mass of the empty tank with the mass of the fluid being transported, the dynamic qualities of the vehicle change so that they differ significantly from the dynamic characteristics of other vehicles. Due to large displacements of the center of mass of cargo in the tank there are additional loads that act vehicle and significantly reduce the course stability and the drivability. We consider the dynamics of liquid sloshing in moving containers, and give examples of building a mechanical model of an oscillating fluid in a tank and a mathematical model of a vehicle with a tank. We also considered the method of improving the vehicle’s stability, which is based on the prediction of the moment of action and the nature of the dynamic processes of liquid cargo and the implementation of preventive actions by executive mechanisms. Modern automated control systems (anti-lock brake system, anti-slip control systems, stabilization systems, braking forces distribution systems, floor level systems, etc.) use a certain list of elements for collecting necessary parameters and actuators for their work. This gives the ability to influence the course stability properties without interfering with the design of the vehicle only by making changes to the software of these systems. Keywords: tank vehicle, roll stability, mathematical model, vehicle control systems.
