Opis:
Newest traffic lights coordination system’s structure contains such components as: local control, global/area control and directional transmissions of data. Today’s wireless controllers, in addition to the standard measurement and signaling functions (handling induction loop circuits, handling double-state signals, handling predefined signal groups), also perform advanced communication functions. With the implementation of such communication technologies/protocols as Ethernet TCP/IP, GSM, GPRS , these controllers are able to send text messages as well as support remote monitoring and control. The beginning of this paper presents shortly chosen examples of current solutions of Zonal Traffic Control Systems. Next a microprocessor model (8051) for controlling traffic lights in an intersection (normal, two-lane) is analysed. Finally the paper emphasises the role of wireless data transmission systems in smart communication in cloud computing and database technology solutions.

Opis:
An application of modern microprocessor technique and more effective microprocessor systems has a large influence on development of devices railway transport and railway automation systems. Functioning new generation railway traffic control and management systems is largely based on Programmable Logic Controllers (PLC), which allow the designers to exploit self-control mechanisms, events registration, technical diagnostics, remote control and fault detection). Railway traffic control and management systems belong to safe technical railway transport solutions, it means that they have to meet the fourth safe integrity level CENELEC (SIL-4), what implies, that the configuration principles and software installed have to satisfy CENELEC EN 50 128 and EN 50 129 standards.

Opis:
The search for system solutions for improving the level of safety in rail transport requires focusing on the problem that is weakly exposed but difficult to manage, namely the elimination of human errors in the process of railway traffic and the use of railway traffic control systems. Despite the fact that the existing solutions have a relatively extensive theoretical layer, there is still much to do in terms of practical implications. In particular, the use of human factors, including knowledge and technology, facilitates the achievement of a number of positive effects: reducing the possibility of errors, increasing the margin of safety, reducing expenditures on redesigning solutions, increasing the efficiency and effectiveness of training, reducing the potential of costly staff turnover and increasing the productivity of the entire organization. This subject has not been solved in a systemic way in Polish conditions. The purpose of the article is to present the holistic and eclectic description of the place and role of the human factor management process in terms of making errors by railway employees, which is designed to eliminate hazards in railway traffic and reduce risk. This has a significant impact on maintaining the expected level of railway traffic safety.

Opis:
This paper presents an idea of development of the OnDynamic system used for non-invasive and low-impact measurements and visualisation of traffic parameters. Planned development would introduce new functionality to the system which allows to observe road traffic impact on the air quality and acoustic climate in a specified area. Network of sensors will be complemented with base stations equipped with the noise sensors, as well as sensors that allow to measure the concentration of the pollutants in the air.

Opis:
The testing of cooperative transport systems is challenging because of their complexity and distributions. With TTCN3 a standard based procedure is available for specifying, executing and evaluating the testing of distributed systems such as cooperative transport systems. In the paper a standard, model and tool based solution for the testing of distributed cooperative transport systems is introduced. Based on the TTCN3 semantic, a specific model based approach for dealing with the complexity of the necessary distributed test systems was developed. With the help of some practiceoriented examples from the traffic sector this approach is presented.

Opis:
Paper presents an experiment using a specialized tool - traffic simulator. The results of computer analysis of traffic have been presented as a very quick, easy and cheap method as base of making complex decisions in the process of organizing traffic. For example, motion simulation for the planned reduction in traffic, resolved the dilemma at the local level, the theoretical analysis at this level is difficult for obvious reasons.

Opis:
In recent years we can see intensifying implementation of Intelligent Transport System (ITS) measures in Polish cities and on national roads. The architecture of the National Traffic Management System (KSZR) will enable the implementation of a uniform, integrated and intelligent ICT system to launch ITS systems that are the most important for drivers and the General Directorate for National Roads and Motorways (GDDKiA). This paper presents the current state of the implementation of the ITS services on national roads in functional, physical and logical terms and the premises for the KSZR’s development. The description of the state of the development of ITS services on national roads was compiled within the framework of the RID 4D “The impact of the usage of Intelligent Transport Systems services on the level of road safety” research project, funded by the National Centre for Research and Development and the General Directorate for National Roads and Motorways.

Opis:
Nowadays, the crucial issue of guidance systems based on a GPS signal is that they are not able to redirect road users, taking into account the current state of traffic (and the predicted state within the time of the travel) in the city. In this paper we present a three layer architecture of a computer system capable of redirecting users of an urban road system via routes with a lighter traffic load in order to reach their declared destination in the city. A basic layer is a multiprocessor calculation server running Dijkstra path search tasks, the middle layer - the one which is visible to the road user - is a replicable proxy server that collects route requests from road users. The third layer is a mobile application. The prototype of such a system was developed by the ArsNumerica Group. The crucial feature of the system is feedback from road users that allows us to adjust the whole Intelligent Transportation System in the city to changes in traffic flow at various road links introduced by the redirection process applied to many users. The performance test strategy to prove the efficiency of the architecture was carried out for the city of Wrocław.

Opis:
Transport safety can be defined in a number of ways, including the official World Health Organisation (WHO) safety definition ‘freedom from unacceptable risk of harm’. Road safety is, however, usually defined in a negative way. Safe road traffic is characterised by the absence of crashes, injuries and fatalities. Crashes are used here instead of accidents because the word accident leads thoughts in the direction of an event that is hard to do something about ľ “it happened by accident”. For society and for the individual, the loss of health is the most serious effect of crashes. It leads both to serious personal suffering and to huge societal losses in monetary terms. Therefore, it is essential to state at this early stage that loss of health is the main road safety criterion. Convalescence and health restoration have economic consequences as have vehicle damage and loss of vehicles and goods.
