Nowadays, there are available on the market not only standard PLCs (Programmable Logic Controller) but also safety PLC´s. These are primarily designed for industrial applications. Their guaranteed safety properties, however, enable to be used in applications, in which the usage of PLC has not been common until now. The aim of this article is to focus on problems related to the usage of safety PLC...
A paper concerns the problems of information ordering in intelligent transport systems accordingly their role and meaning for various transport processes. There is given an attempt to rules of classification of information, their standardisation questions, reduction of redundancy and false specimens necessary for proper information management. All these questions are of great importance from the information...
The paper presents an analysis of the basic principles of telematic systems in which the timely execution of tasks and the interaction of those systems distributed modules is the critical element. The first part lists the most important ideas and concepts of real-time systems. The second part refers to the communication principles of elements of a distributed telematic system-level exchange of messages...
The paper describes the principle and operating range of currently used satellite monitoring devices of working machines. The paper presents some possibilities of satellite control systems of working machines. We analyzed the impact of satellite monitoring equipment work on the fuel consumption during the operation of excavators.
Most of the vehicles, which can be observed by the cameras used in the Intelligent Transport Systems, are coated with reflective layers which, like car windows, are characterized by the effect of light polarisation. Utilising this effect by using a camera designed for the Intelligent Transportation System along with the linear polarizer it is possible to improve the extraction of the vehicles from...
The study contains a description of the use of GIS tools in compensation proceedings using the example of the area of limited use set up for the Katowice International Airport in Pyrzowice. Additionally, the study describes the development history of the system so far and presents future trends allowing integration of the existing system with projects fulfilling requirements of particular airport...
The paper considers an intelligent electronic embedded system for the protection of railway transport from accidents, its compatibility with the existing railway control system, principles of its components interoperation and control algorithms. The paper gives the definitions of the functions performed by the system considered and its mathematical description applied to the realization of the control...
This article presents the current problems with measuring distance in goods wagons. The main problem where goods wagons are concerned is their lack of power supply. Owing to this, a distance-measuring system is hard to install. Meanwhile, the measurement of distance travelled and the service processes dependent on this measurement are becoming more and more important. Moreover, the railway accident...
One of the most significant road structures completed in 2010 was the construction of southern part of the Bypass around Prague (BPAP), where technological equipment was designed and installed and Road Line Traffic Control system implemented. In the Czech Republic is this system is absolutely innovative and brings new organizational and regulation elements into operation. The system is primarily intended...
The article describes public transport co-modality for sustainable development of a public transport system. New strategies are needed to make the city public transport more efficient, more accessible and more sustainable. There are some concepts described in the article. The concepts are illustrated with practical examples - how it is possible to increase the capacity of infrastructure and what has...
The paper presents information of the project and the results of research on the problem of monitoring and management of information about occupancy of parking spaces in real time. The material draws attention the potential which, being properly used with adequate detection of the presence of selected technology and the desired transmission of information in graphic form for selected locations respectively...
Planning and realization of ship route is a complex problem, which consists of elements from different disciplines. It is necessary to take into account: the formal requirements, the organization of traffic in restricted areas, exploitation limitations of the ship; economic issues relating to the costs of fuel and the costs associated with the possible unscheduled reaching the ship at the port of...
The article presents review of methods and devices for track measurement of rail vehicles in aspect of diagnostics and safety of use. Currently used solutions do not enable effective "on-line" measurement of mileage by wheelsets and vehicles' axles in rail vehicles without electric power supply such as goods wagons and cisterns. Those solutions have limited functionality and have to use...
The paper is a form of mathematical description of the tool - a computer whose primary function is to manage liquidity through follow-up control of the traffic (in less than 1 second) to send signals to the drivers of management traffic light intersections of application is mentioned. The purpose of this paper is to provide reliable knowledge in this area with particular emphasis on implementation...
One of the major advantages of the video cameras' usage for tracking of vehicles is to reduce the costs of Intelligent Transport Systems. However, this requires the development of software techniques allowing an automatic extraction of the vehicle or group of vehicles from the current video frame, which is possible by using the background estimation methods, assuming a fixed camera installed over...
Communication between vehicles is very important element of accidents reduce. In this contribution is made accidents analysis in SR and is described all the available techniques for communication between various vehicles among themselves and with the infrastructure. The aim of this is to have a complete overview of all the possible communication techniques that the world of electronics and telecommunications...
The paper deals with functional and safety analysis of transmission in railway control systems, especially fail-safe applications (Line Block System, Dispatcher/Interlocking, Cross Level Protection and monitoring remote control). An analysis of the data structure is presented with recommended protection mechanisms to determine the indexes of time used for safety proof. The typical standards used in...
