Opis:
The aim of the article is to present the influence of changing station layout over interlocking systems in train routes. There is often a problem in the process of doing for example application of interlocking system in exactly bigger stations when there are track changes in next phases of the project. Vividly small changes can influence in significant way for realization train and manoeuvre routes in such station. In case of that it is necessary to search the shortest road of making documentation and software which could be changes resistant. This resistance resulted by for example necessity of continuing leading railway when there is modernization on the station.

Opis:
As the urban traffic volumes reach their daily peak values, the surface traffic in modern cities suffers from frequent breakdowns and traffic jams. One of possibilities that could mitigate the problem is the deployment of smarter automatic systems of urban traffic control. Our paper demonstrates a development version of such a system. The system is based on adaptive feedback control approach. It makes use of filtering techniques to account for measurement imperfections and implements the rolling horizon method for optimal signal control. We compare the performance of the proposed system with two typical control approaches - pre-timed (or fixed) control, and traffic actuated (or dynamic) control. Different scenarios will be compared, including rapid changes in traffic volumes and reactions to incidents. The comparison is carried out using our demonstrator tool, based on TSS Aimsun micro-simulator. In order to keep the calibrated simulation as close to reality as possible, in the comparison runs we use real dense input volume measurements and simulate also the behavior of intersection controllers.

Opis:
The paper presents an evaluation of the properties of the vehicle detection system comprising the source of data of traffic flow for road traffic control in a city. The quality of traffic data determines the ability to reach optimal traffic control decisions. Errors of measuring traffic stream balancing locally at junctions and in the whole of the road traffic control system are chosen as evaluation criteria. The city traffic is modelled using a directed graph, with vertices being the measurement sites and with edges linking vertices having weights representing traffic flow values. The analysis of the results enables the determination of measurement sites inadequately mapping the road situation and allows proposing new sites to improve the system. The analysis is performed using real traffic data acquired from the Traffic Control Centre in Gliwice

Opis:
Telematics systems development has already become a necessity due to the limited capacity of the road infrastructure. Transport can thus be better managed; also relevant information can be provided directly into the vehicles. Based on the development of communication technologies, namely „car-to-infrastructure” (C2I), the requirements are continuously rising – not only on the on-board units (OBU) but also on the infrastructure equipment and solution of particular modules for traffic management systems as well. The paper focuses on the design and simulation of control system in an intelligent unit on infrastructure that will be able to respond to the actual traffic situation and to communicate with the vehicles. The goal of this paper is to present the possibility of using such units in urban road infrastructure and to present an approach to traffic nodes management for saturated or over-saturated traffic states.

Currently used, computer railway traffic control systems , communicate via standard digital interfaces: CAN, Ethernet or RS485. In order to carry out the proof of security, it is necessary to test the functioning of the interfaces under different conditions. The IBIS model (I/O Buffer Information Specification) was used to simulate the transmission of signals through interfaces. The article discusses the applied interface models and simulation results in various conditions. The presented results can be used to prove the safety of transmission in computer railway traffic control systems.

Opis:
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 for traffic flow harmonization. It is based on usage of variable message signs to affect the traffic flow so the fluency, security and communication permeability is increased. Thank to automatic speed reduction by defined traffic data is traffic flow is more fluent, distances between vehicles are smaller and throughput of communication increases. RLTC system can identify traffic excesses on communication thanks to vehicle queue detection. All algorithms were designed and tested under project of science and research of Ministry of Transport of the Czech Republic, project INEP, n. CG944-033-120 (inep.eltodo.cz). In current time testing operation on BPAP and on a part of D1 Highway is proceeded. System is monitored and all functionalities are evaluated for further debugging and adaptation of system for local conditions.

Opis:
The paper introduces a self-organizing traffic signal system for an urban road network. In the presented system, the traffic control decisions are made on the basis of predictions that are obtained from a fuzzy cellular traffic model. The fuzzy cellular model represents traffic streams at the microscopic level. Therefore it can directly map parameters of individual vehicles and the vehicle classes can be taken into account in making the control decisions.Simulation experiments were performed to compare the performance of the self-organizing traffic control for twoscenarios: first, when the class of vehicles is taken into account and second, when the information on the vehicle class is unavailable. Results of the simulations allow us to explore the possibility of performance enhancement of the urban traffic control through the utilisation of microscopic traffic models and vehicle classification systems.

Opis:
The A4 Motorway is the key transport connection in southern Poland and carries domestic and international traffic in the east-west direction. In 2008 a traffic management system based on variable message signs (VMS) was designed for the General Directorate of National Roads and Motorways. The system covers a section of 165 km of the A4 Motorway between the interchanges Bielany (Lower Silesia) and Sośnica (Silesia). The main purpose of the system is to ensure seamless traffic flows and road safety. Thanks to the application of VMS and a dynamic transfer of data and information the functions of the system include traffic control, speed management, alternative route guidance, traffic information and weather warnings. The design stage of the system included the mapping of data sources, grouping of potential traffic incidents, development of message signs, setting out of actuation procedures and sequences of message display as well as outlining of communications procedures and decision making process by the administrator of the system. A lot of attention was given to factors providing for reliability of the system and credibility of messages.

Opis:
In the field of railway transport many activities are taken to achieve higher availability of offered services. A few of them consider more flexible rules of creating and starting trains. This requirement translates into greater complexity of railway traffic opertional management and control (RTMC). At the Faculty of Transport of Warsaw University of Technology classes for students have been conducted for several years with the use of the KSR-EDU stand. Taking into account the described trends of railway traffic nature, the KSR-EDU stand was connected to a simulator of real railway traffic. This connection allows to practice various and more complicated movement scenarios. The article describes RTMC layer model and simulator architecture in general. Two simulation tasks are described in details. The algorithms of simulation tasks for different levels of simulation are presented. In the end the benefits arising from application of the simulation for particular didactic tasks are discussed.
