Opis:
Selection of components in contemporary computer networks is extremely important, not only because of the project budget but also because of the network performance. Therefore, it is necessary to perform tests before deploying devices. In this paper the authors show that the performance of test network devices is dependent on the nature of network traffic including its statistical properties. Also a new hybrid model of the system for testing the network device based on the q-additivity of traffic flows was proposed.

Opis:
The Traffic Flow Description (TFD) option of the IP protocol is an experimental option, designed by the Authors and described by the IETF’s Internet Draft. This option was intended for signalling for QoS purposes. Knowledge about forthcoming traffic (such as the amount of data that will be transferred in a given period of time) is conveyed in the fields of the option between end-systems. TFD-capable routers on a path (or a multicast tree) between the sender and receiver(s) are able to read this information, process it and use it for bandwidth allocation. If the time horizons are short enough, bandwidth allocation will be performed dynamically. In the paper a performance evaluation of an HD video transmission QoS assured with the use of the TFD option is presented. The analysis was made for a variable number of video streams and a variable number of TCP flows that compete with the videos for the bandwidth of the shared link. Results show that the dynamic bandwidth allocation using the TFD option better assures the QoS of HD video than the classic solution, based on the RSVP protocol.

Opis:
Providing a Quality of Services (QoS) into current telecommunication networks based on packet technology is a big challenge nowadays. Network operators have to support a number of new services like voice or video which generate new type of traffic. This traffic serviced with QoS in consequence requires access to appropriate network resources. Additionally, new traffic type is mixed with older one, like best-effort. Analysis of these new and mixed traffic types shows that this traffic is self-similar. Network mechanisms used for delivery of quality of services may depend on traffic type especially from the performance point of view. This paper presents a feasibility study done into the effect of traffic type influence on performance of routing algorithm while the routing algorithm is treated as one of the mechanisms to support QoS in the network.

Opis:
Feasibility studies with QoS routing proved that the network traffic type has influence on routing performance. In this work influence of self-similar traffic for network with DiffServ architecture and OSPF QoS routing has been verified. Analysis has been done for three traffic classes. Multiplexed On-Off model was used for self-similar traffic generation. Comparison of simulation results was presented using both relative and non-relative measures for three traffic classes. Results were commented and analyzed. The basic conclusion is that performance for streaming and best-effort class for self-similar traffic is higher than performance for the same class with exponential traffic (Poisson). The other important conclusion is relation between performance differences and offered traffic amount.

Opis:
The research on improvement of methodical approaches to definition of the probable reasons of infringement of conditions of stability of freight cars from derailment is carried out. Using a basic computer model of the dynamics of a freight car, the influence of the characteristics of the technical condition of their running gear and track on the indicators of empty cars stability from derailment was studied through the computational experiment. The article presents the main statements of the research methodology, which provides the analysis of probable causes of derailment of freight cars by conducting a series of numerical experiments with logging the progress of calculations and saving the results. Factor analysis was used to interpret the calculated data with an assessment of each of the factors influence or their combination on the probability of derailment. The developed procedure of the simulation experiment provides a step-by-step study of the freight cars derailment conditions, including factors structuring and ranking, development of experimental plan, calculating coefficients of wheel pairs resistance to derailment from rails, provided that the wheel flange rolls onto the rail head, and determining the degree of influence of relevant factors on the dynamic stability of cars from derailment. A comparative analysis of the stability of cars in rail tracks was performed using the introduced concept of the combined coefficient of stability of wheel pairs against derailment. Determining the probable causes of car derailment is based on scanning the parameter field. The results of the parametric study revealed the degree of influence on the freight cars stability of running gear technical condition characteristics. In particular, it is determined that the most dangerous in terms of stability loss of empty cars in the track is the exceeding of the wedges of the vibration dampers.

Opis:
When we study any queuing system, the performance measures reflect different features of the system. In the classical M/M/1 queuing system, traffic intensity is perhaps the most important performance measure. We propose a fresh and simple estimator for the same and show that it has nice properties. Our approach is frequentist. This approach has the dual advantage of practical usability and familiarity. Our proposed estimator is attractive as it possesses desirable properties. We have shown how our estimator lends itself to testing of hypothesis. Confidence intervals are constructed. Sample size determination is also discussed. A comparison with a few similar estimators is also performed.

Opis:
Currently it is assumed that requirements of the information society for delivering multimedia services will be satisfied by the Next Generation Network (NGN) architecture, which includes elements of the IP Multimedia Subsystem (IMS) solution. In order to guarantee Quality of Service (QoS), NGN has to be appropriately designed and dimensioned. Therefore, proper traffic models should be proposed and applied. This requires determination of queuing models adequate to message inter-arrival and interdeparture time distributions in the network. In the paper the above mentioned distributions in different points of a single domain of NGN are investigated, using a simulation model developed according to the latest standards and research. Relations between network parameters and obtained message inter-arrival as well as interdeparture time distributions are indicated. Moreover, possibility of approximating the above mentioned distributions using phase-type distributions is investigated, which can be helpful in identifying proper queuing models and constructing an analytical model suitable for NGN.

Opis:
The reports of committees investigating the causes of rail accidents indicate the significance of the so-called human factor (e.g. UTK, 2019). In addition to issues related to perso nality functioning, the organization and culture of work, this also includes variables related to the cognitive functioning of train drivers themselves. These are significant factors that determine the occurrence of accidents that result from ignoring or not spotting railway signals and signs. The purpose of this study was to verify the relationship between cognitive functioning and safety determinants, which was measured using an eye-tracking technique. The application of this technique was intended to check its usefulness in the field of railway traffic safety and to achieve an approximate simulation environment of the real working conditions of a train driver. In the present study, the Vienna Test System was used as a me - thod for the determination of cognitive functioning. Based on the variables described in the subject literature, the following tests were applied: Determination Test, Visual Memory Test, Visual Pursuit Test, Reaction Time, Cognitrone, Signal Detection and Vigilance. In addition to computer cognitive tests, an eye-tracking test method was designed based on a film recorded in real train-driving situation. Measures describing areas of interest (AOI) that are crucial for safety were analysed. Due to the pilot nature of the research, only 10 passenger train drivers participated in the study. The results of the study showed a link between the cognitive functioning of the train drivers and visual security determinants. Significant correlations were found with stress tolerance resulting from cognitive overload, visual memory, alertness and concentration ability under time pressure. The study confirmed the significant role of the train driver's cogni- tive functioning in the analysis and perception of safety-critical signals. The use of an eye-tracking method has delivered results that are in agreement with studies based on other methods. This pro- vides a sound basis for the continuation of research using eye- tracking in the assessment of rail transport safety. In the future, the research should be extended to include an analysis of the effect of demographic and situational variables (types of signalling devices and signage) and a broader model of the relationship between cog- nitive functioning and the driver's visual attention. This will provide data that is crucial for the prevention of railway incidents and the development of training plans for train drivers.

The research into the use of less costly modifications of road links and networks, and changes in the service of road surroundings aimed at ensuring an improvement of through traffic performance in suburban areas, and on roads passing through built-up areas as small localities, with application of simulation model, is presented in this paper. From among possible designs, the authors investigated and presented the effectiveness of two, i.e. implementation of an additional multifunctional median lane in the road cross-section, and construction of service roads with different locations of intersections (end or middle of the road section). The analysis is focused on the impact of such changes on traffic performance and road safety. The authors analysed travel speed, delay and share of platoon traffic on a uniform sections of the road for different types of road surroundings service. The study presents the results of analyses of road network before and after modification, and the assessment of: impact of access points density and level of their use on road traffic performance, impact of driving through road sections in built-up area on building platoon traffic, impact of change in the cross-section type on traffic performance.

Opis:
The author investigated traffic flow quality on a new 2+1 long road bypass with an exceptionally high share of heavy vehicles in order to assess rational limits of heavy vehicle shares in traffic flow, dependent on the length of the 2+1 road and the number of passing segments in each direction. This paper presents the results of traffic flow quality analyses through the use of empirical and simulation methods for a single 2+1 road segment with additional passing lanes, as well as for the study of the entire section of the bypass – 2+1 road. Variables include analysis of travel speed distribution, platoon traffic, and amount of passing maneuvers. Results show that large passing demands lead to very high speeds (over 100 km/h) on segments with additional passing lanes. The conclusions include remarks related to the use and operation of 2+1 cross-sections with high shares of heavy vehicles.
W artykule przedstawione zostały badania warunków ruchu na odcinku drogi 2+1, stanowiącym obwodnicę Żyrardowa, z wyjątkowo dużym udziałem pojazdów ciężkich. Celem artykułu była ocena wpływu zmiany udziału pojazdów ciężkich na warunki ruchu dla pojedynczych odcinków 2+1 jak i dla całego odcinka drogi 2+1 składającego się z naprzemianległych odcinków z dodatkowym pasem do wyprzedzania. Przegląd literatury zagranicznej wskazuje na duże korzyści w zakresie funkcjonowania przekrojów 2+1 w odniesieniu do warunków ruchu. W większości opisywanych badań udział pojazdów ciężkich nie przekraczał w warunkach rzeczywistych 20% lub w symulacyjnych 30%. Obserwacja problemów funkcjonowania obwodnicy Żyrardowa, na której występuje wysoki poziom udziału pojazdów ciężkich spowodowała konieczność podjęcia badań w tym aspekcie. Prace badawcze obejmowały badania empiryczne i analizy symulacyjne. Badania empiryczne realizowane na obwodnicy Żyrardowa obejmowały analizę odcinków z dodatkowym pasem do wyprzedzania oraz całego odcinka drogi 2+1. Zostały one wykorzystane do wstępnej oceny warunków ruchu oraz jako dane do kalibracji i weryfikacji modelu symulacyjnego.

Opis:
The GNSS positioning performance is commonly defined and described in terms unspecified to particular GNSS-based application. The approach causes difficulties to GNSS application developers, operators, and users, rendering the impact assessment of GNSS performance on the GNSS application Quality of Service (QoS) particularly difficult. Here the Probability of Occurrence (PoO) Model is introduced, which allows for a risk assessment of the probability for the GNSS positioning accuracy failure to meet the requirements of the particular GNSS-based application. The proposed PoO Model development procedure requires a large set of position estimation errors observations, which shall cover a range of classes of positioning environment (space weather, troposphere, multi-path etc.) disturbances affecting GNSS positioning accuracy. As result, the PoO Model becomes a tool that returns the probability of failure in meeting the positioning accuracy requirements of the GNSS applications considered, thus providing the input for a GNSS deployment risk assessment. The proposed PoO Model and its development procedure are demonstrated in the case of polar region positioning environment, with raw GNSS pseudorange observations taken at the International GNSS Service (IGS) Network reference station Iqualuit, Canada are used for the PoO Model development. The PoO Model proof-of-principle is then used to estimate the probability of the unmet required positioning accuracy for a number of polar maritime navigation applications. Manuscript concludes with a discussion of the PoO Model benefits and shortcomings, a summary of contribution, and intentions for the future research.

Opis:
The article discusses selected provisions of EU aviation law concerning economic issues of air traffic management. This process in European airspace is carried out by air navigation service providers, which, unlike airport operators and air carriers, have a monopolistic position and do not operate under market conditions. Consequently, the lack of competition between air navigation service providers replaces the common charging system for airspace users established by European Union law. In order to increase the cost-effectiveness of the services provided while maintaining a high level of safety of air operations, the navigation charges system was linked to the parallel implementation of the Single European Sky performance scheme for air navigation services in 2010. In 2019, the rules governing both systems were consolidated into a single legal act. The study also looks at the basic indicators of economic efficiency of air traffic management based on the example of the Polish Air Navigation Agency.

W artykule zaproponowano metodę klasyfikacji warunków ruchu na drogach wielopasowych na podstawie zdjęć z filmu pochodzącego z monitoringu dużego skrzyżowania wykonanego z użyciem drona (UAV - Unmanned Aerial Vehicle). W metodzie wykorzystano technologie przetwarzania obrazów oraz cechy obrazów teksturowych, takie jak: energia, entropia, kontrast, jednorodności, podobieństwa, korelacja. Cechy te poddano analizie wybierając pięć najbardziej wyróżniających cztery klasy warunków ruchu. Klasyfikację wykonano za pomocą sieci neuronowej. Przeprowadzona walidacja modelu wykazała, że zaproponowana metoda może być wykorzystana do klasyfikacji warunków ruchu.
The paper discusses the application of texture analysis of road traffic images for determination of traffic conditions. The capability of mapping traffic conditions is investigated using such texture features as: energy, entropy, contrast, homogeneity, dissimilarity, correlation, captured by cooccurrence matrices. An optimal combination of features is chosen for classification of traffic condition levels. Four classes of traffic conditions are correctly differentiated using the proposed texture model of road traffic images. Classification was performed using a neural network. The model is validated using images registered by an UAV flying over a traffic junction.
