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.

Traffic Control System

One of the elements of implemented in Poland traffic control systems is module of priorities for public transport. Essence of working priority and the basic indicators of its effectiveness were presented. Among methods for testing the effectiveness of the priority, there has been distinguished economic and simulation approach. An example of priority research based on simulation of chosen street in Bydgoszcz was shown, using Vissim simulation environment. Developed simulation model, its connection to the control system, adopted detection system and 4 tested control strategies were also described. Then, the simulation and its results were presented. In results discussion they were compared in terms of adopted control strategies. In summary, possibility of a future study extension was also indicated.

This article discusses the issues of operating data in national and European Rail Traffic Control systems, i.e. in the ERTMS / ETCS and SRK systems. The article presents the possibilities and limitations of ERTMS systems. General principles of system implementation are also given, as well as specific functional levels of the Rail Traffic Control System are presented. The article describes and presents operational data related directly to the railway systems, which are based on the standard described in document E-1758. The article draws attention to the complexity of Rail Traffic Control processes, as well as the fact that it is necessary to modernize solutions that in the coming years will be a real challenge for the railway industry..

Traffic Management System

With the increasing use of railway transportation, various methods have been developed for the control and management of train traffic. Train traffic control systems that are currently in use are overwhelmingly centralized systems. In this study, the development of the general structure of railway traffic control techniques is examined, centralized and decentralized control systems are investigated, and an alternative train traffic control system, the Decentralized Train Traffic Management System (DTMS), is suggested. Simulation results on the possible application of the proposed method to a railway line in South-East Turkey are employed to evaluate the performance of the developed system.

Traffic Control System

The Federal Aviation Administration, at its National Aviation Facilities Experimental Center, has recent ly completed a new air traffic control system Digital Simulation Facility. The facility allows for improved real-time systems simulation and is currently being used to support two important pro jects aimed at improving control and safety of air traffic: It is being used to evaluate the inter action between a proposed airborne collision avoidance system and the air traffic control system, and to validate the various levels of automation in the air-terminal automation development program. The facility was developed for simulating present and proposed air traffic control systems and has twelve digital displays, five used as pilot consoles and seven as controlleer consoles. Each is equip ped with data entry devices for communicating with the computer which controls the simulation. This article describes the operation of the system, the hardware which comprises it, and the software required to control the equipment, to simulate air craft flights, and to collect and reduce data. Advantages of the new simulation facility over prior ones are discussed, as are plans for its use and expansion. The new facility provides an environment for con ducting simulations required in developing improved air traffic control systems to meet the needs of our increasing air traffic.
