Opis:: The article deals with the problems connected with road traffic safety highlighting driver’s ability to notice an untypical obstacle in the light of low beam headlights while driving in the night. Visibility of an unlit object during the night is not only related to its motion but also to the necessity of its being lit to up to the required minimum height. On the basis of a study of a road accident, it was found that the standards accepted in reconstruction of the accident for determination of the light beam height to be used for lighting an obstacle should not be taken for granted. The driver’s surprise at the sight of an unlit obstacle is accompanied with the need to direct the light beam higher, which causes shortening of the distance available for a driver to react in an attempt to avoid hitting into an obstacle. An analysis of this case shows that verification of road accidents involving a crash with an untypical, incompatible obstacle that happen during the night needs to be carried out with attention and care. A simulation program V-SIM4 version and Ratschbacher AutoView database was used for calculation of the possibility to avoid an accident. The results obtained on the basis of the authors own investigations can also be used in information campaigns, education for road safety improvement and development of proper attitudes of the road traffic users.

Opis:: Every year in Poland, approximately 22 million tons of dangerous materials is transported, which, apart from the German railway, places it on the second position in Europe. The most numerous group of dangerous materials include items of class 3 (liquid, flammable materials), especially liquid fuels. In order to prevent accidents and remove their effects, the European Union countries have developed an international code regulating transport of dangerous materials by railway, RID. Every year 110 billion ton kilometres of dangerous materials are transported on the territory of the EU. Materials carried by road transport account for 58%, by railway 25% and by water 17% of all the transported dangerous products. Transport of dangerous materials accounts for 8% of all freight transports in the European Union. Having in view natural environment protection and safety of people, there are carried out works on one legal act to account for all the three transport branches. Railway transports of dangerous materials are performed in a safe way and rare, in terms of the transports number, accidents and failures do not cause harmful effects, neither on people nor the natural environment. In the paper, there has been made an analysis of transport procedures and threats which occur while carrying dangerous materials. On the basis of carried out investigations an assessment of the risk factor in the studied process has been presented. General rules for transport of dangerous materials by railway and their classification have been presented, markings according to RDI regulations. An attempt of threats identification and analysis of the maim causes of undesirable events occurrence during railway transport of dangerous materials has been made by the authors of this work.

Opis:: A correctly designed machine is characteristic of low vibration values. However wear processes occur during its operation. They are accompanied by a lack of balance of its rotating parts and elements, which results in non-coaxiality of shafts. For this reason energy and dynamic load resulting from machine vibrations grows. In this case cause and effect are mutually connected by feedback, that inevitably leads to occurrence of a failure. This paper presents results of investigations carried out on the basis of vibration analysis of propulsion systems installed on 207P minesweepers. In view of specific features of their operation it is very important to ensure high level of reliability for them. For this reason was done an attempt to develop a method intended for identifying non-coaxiality of shaft line systems of engines propelling the ships. 16 characteristic features of recorded vibration signals were selected. As any of them has not satisfied criteria assigned to features which unambiguously determine state of reliability of shaft line systems, the investigations have been continued and as a result a novel method for non-coaxiality identification was proposed. The method consists in determining unserviceability clusters and assumes that characteristic features are of a concentrated character. This way a non-coaxiality of main engine shaft lines of 207P minesweepers could be detected. This paper presents the proposed method and results of its application to the case in question.

Opis:: This article deals with the modeling of the processes of operating both marine main and auxiliary engines. The paper presents a model of changes in operating conditions of ship’s internal combustion engine. The semi-Markov decision process was used to mathematically describe the process model of the engine. The developed model describes the effect of engine damage on the characteristics of its operation. A change in the input parameters of the model can simulate the influence of internal and external factors on the course of the analyzed process. A simplified calculation example is also presented for illustration purposes. The presented method together with developed algorithms and IT tools can be used to solve a wide range of problems related to the operation of marine main engines and other marine equipment as well as maritime and port facilities. This concerns primarily the economic, risk management and operational security issues of complex technical systems, as well as the readiness and reliability analysis of technical facilities.

Opis:: The study deals with the problems connected with evaluation and analysis of transport systems operational quality. The research object is a real, sociotechnical system (of the type H-M-E) whose functional quality is affected by: operators, equipment and technical state of he operated vehicles and the environmental impact. A scheme of an assessment model was built on the basis of a developed concept of a system operational quality and a random process was defined to be used for the analysis. The assessment process involves investigating the variability degree of properties included in the resultant model in a given time and determining whether and to what degree the obtained values meet the requirements of the system appropriate operational quality. On the basis of the above assumptions and in result of experimental tests, four qualitative states of a transport system functioning, which represent intervals of values of the obtained grades in given time moments, were distinguished. The study presents a model of system operation qualitative state changes developed with the use of Markov chain inserted into a certain semi-Markov process. A graph and a matrix for probability of transition between the states were created and boundary distributions of the process were determined on the basis of experimentally obtained data. A system of equations was determined for the distinguished Markov chain, on the basis of which a mathematical model for assessment and control of operational quality of selected types of transport systems will be built.

Opis:: The study deals with the issue of durability extension of multi-phase gears working under temporary or constant loading. The tests were performed for transmission oils used in power transmission systems of beet washers of DC type used in sugar plants. The lubricity parameters of oils and the possibilities of their modification through introduction of low-friction additives to the oil were studied. Additionally, the noise level emitted by working gears was measured before and after addition of the modifier. Lubricity tests were performed on semi-Timken apparatus, on which friction pairs friction roller- roller were tested with the use of oils extracted from the gear. SoundMeter application with MIC002 microphone adaptor was used for measurement of the noise level emission. Tests results have confirmed efficiency of the modifiers as higher values of friction loading were obtained and the noise emission level was reduced. It has been proven that in real operation systems, there is a possibility to increase the value of transmission oil lubricity parameters, which has a direct impact on durability of friction pairs of a gear during its operation.

Opis:: Reaching of high parameters of a drive unit and low pollution of the natural environment is considered to be the most desired effect of motorization. The use of the additive in the form of fatty acid methyl esters to the diesel oil, assumes lowering of harmful fuel gases’ emission and reaching high operating parameters of an engine, such as power and turning moment. Studies on the power output and the turning moment of an engine with self-ignition are presented in the study. The subject matter of the studies was a combustion engine with self-ignition of the power of 80 kW with the direct common rail system and turbo-compressor’s supercharging and with electromagnetic injectors. The tested engine was powered with diesel oil and the mixture of fatty acid methyl esters and the diesel fuel, in proportions 10%, 30% and 50% with an improver, at the standard settings of the fuel injection controllers. The vehicle used for the testing purposes, has been singled out with respect to the specific features, such as: universality of its use as a means of transportation and the opportunity of modification of the injection parameters, resistance to possible unfavourable consequences resulting from the use of the fuel mixture. The studies were conducted on a chassis test house, at full engine’s loading. The vehicle placed on the test house’s rollers, was strapped with belts to the foundation, and then accelerated up to the specific speed and subjected to loading standing in place. In such a manner, the road conditions were simulated. The obtained results of the tests were subject to the statistical analysis. From their analysis it results, that application of the mixture lowers the engine’s parameters to a degree unnoticeable at the time of its operation.

Opis:: The article presents the results of laboratory tests of selected properties of fuels available on the market and fuels with higher density component B100 obtained from rapeseed oil (10, 30, 50 and 100%). An analysis of the cetane number, viscosity, and weight of the ash remaining after combustion of fuel samples was made. It was found that the cetane number of pure biocomponent is higher than diesel oil of mineral origin and it slowly decreased along with a decrease in the Extras component. All tested samples of fuels have appropriate cetane number to power internal combustion engines with compression ignition. The viscosity of the fuel samples measured at a temperature of 30ºC increased along with an increase in the content of biocomponent and approached the limit values for fuels. According to the results presented by other authors in their studies ash mass decreased along with an increase in the content of the component. Only premium diesel showed less ash mass than other fuel. The study includes also the energy value and the calorific value of liquid fuels with addition of a biocomponent, which power diesel engines. The results of the tests indicate a slight decrease in the calorific value of the fuel along with an increase in the content of biocomponent, which does not affect the ability to power the engines. Laboratory tests have proved that use of methyl esters of fatty acids in diesel fuel is the right choice to power diesel engines.

Opis:: Ship large-power steam boiler may serve as an example of complex critical technical system. A basis for rational control of operation of such system is knowledge on its capability of fulfilling the tasks to which it was intended. In order to make it possible to apply computer aiding to operational decision-making the capability should be described analytically. In this paper it was proposed to express the capability of ship steam boiler ( considered a complex system) to perform service tasks, by calculating components of its usability potential in a given instant t. To this end , was distinguished a set of steam boiler fundamental features which formulate space of its technical states. Values and characteristic intervals of the features were defined and this way sub-spaces of serviceability and non-serviceability states of the object in question were determined. Next, in the considered space, technical state of the boiler and its usability potential was determined. Owing to this it become possible to quantitatively express the steam boiler functioning capability which served as a basis for elaborating an algorithm for controlling the operational processes of a complex technical system under action. In this paper is also described a way of application of the presented method to calculation of ship steam boiler usability potential, which may be especially instrumental in the case of operational control of the boilers of the kind , equipped with interstage reheaters, i.e. those operating with high values of operational parameters.

Opis:: This study presents an analysis and evaluation of application of European Car Modular Systems in the Polish road transport. Those systems and respective terminology have been analysed and classified. Application of such systems in other countries of the European Union has been described. SWAT analysis has also been carried out in order to enable the most optimal choice of modular system in freight transport to match the condition and characteristics of the Polish road infrastructure. The systems have also been analysed in terms of efficiency and the analysis was performed on the basis of a selected research object – a transport company. An analysis of costs and estimated profits from transport services to be provided by those systems has been carried out on the basis of the research object in comparison with costs borne by the considered company with currently used transport means. This study shows that taking into consideration the results of analyses, safety aspect, road infrastructure and energy efficiency of the vehicles it was found that the proposed oversized vehicles could be implemented to be used on the Polish roads. The analyses and tests performed for a transport logistic company discussed in this article have demonstrated that the proposed modular systems will undoubtedly allow reducing significantly the costs of transport services by increasing load capacity of vehicles.

Opis:: Road safety is an important social issue. Hence, changes in road traffic rules have a large influence on travel safety improvement. One of the major issues to be addressed is the speed limit of motor vehicles and radar speed measurements. Moreover, road traffic rules impose the obligation to wear safety belts during driving, carrying children in car safety seats and they put a ban on drink driving as well as driving under the influence of other intoxicating substances that have a negative influence on the driver’s physical condition and driving skills. This study analyses changes in traffic rules and provides assessment of the way they affect road traffic safety in Poland. The study presents an analysis of the issues connected with road vehicle operation and safety of the passengers including: wearing safety seat belts, use of children car safety seats, vehicle lighting, speed limit. Such issues as the proposed changes in breathalyzer use and implementation of safety systems to provide road users with safety have been addressed.

Opis:: Continuous and dynamic development of freight transports, especially in the road sector, results in generation of negative effects on the environment and poses hazards to human health and life and by generating high costs it creates significant economic, social and environmental problems. Therefore, it is necessary to take actions aiming at promotion of development of sustainable and efficient transport systems, integrating different transport branches and technologies. Such requirements are fulfilled by the subsystem of inter-mode transport system, that is, combined transport which is an alternative for a traditional road transport, and can also play a very important role in achieving goals of the European policy for sustainable development of transport. Its promotion can largely contribute to solving present and future problems connected with transport in Europe through relieving excessively loaded roads from a certain portion of freight transports which will result in improvement in the traffic safety and reduction of its negative impact on the humans and the environment. Providing high quality of inter-mode transport operation, especially in terms of reliability, punctuality, safety and keeping delivery terms depends on the infrastructure state, modern equipment of terminals and efficiency and effectiveness of their functioning. It should be emphasized that promoting inter-mode transport provides social benefits on a big scale as shifting a part of international road transports into a combined one inter-mode can have a significant influence on reduction of the road transport external harmful effects. In this paper, there has been made an analysis and assessment of inter-mode transports in Poland, taking into consideration the motor and railway (linear and point) infrastructure. Also, a suggestion concerning the location and construction of terminals for the service of inter-mode transports has been considered. Moreover, a technical-economic analysis of implementation of the discussed solution purposefulness has been made as well.

Opis:: This study deals with the problems connected with evaluation of technical systems efficiency of particular transport systems. The main goal of such a system operation is its effective functioning, through rational control of its particular activities and subsequent processes. A literature analysis of the definition of the efficiency term has been made. A real transport system has been accepted to be the research object. The system belongs to the group of sociotechnical systems in which evaluation of its operation efficiency depends on performance of operators, transport means and the impact of environmental factors. Criteria and methods of operation efficiency evaluation have been determined in this study as well as assessment indexes for transport systems. It has been shown that evaluation of a repair efficiency has a large influence on the efficiency of the whole system operation, especially the influence of secondary failure repairs, on the values of particular efficiency indexes. A semi-markov model of operation and maintenance of transport means used in the research object has been developed. This model provides the basis for evaluation of the influence of the processes involved in preparing transport means for service on the system operation efficiency. Moreover, the research also describes how to verify the developed model and present its simulation tests. The study is summarized with conclusions formulated based on the evaluation of the influence of the operation and maintenance processes on the investigated transport system operation efficiency.

Opis:: The basis of operation systems functioning is their ability to accomplish set goals, in given conditions, place, quantity and time. Assessment of their operation quality is a summary measurement of their efficiency, reliability, safety, environment friendliness and ergonomics. The analysis of literature on this subject proves, that studying the systems operation quality is one of the main factors, which make up the processes of their service, repairs, control, supply, diagnostics, and most of all, operation of used machines and devices. The studied systems belong to socio-technical systems of the type H–M–E (human–machine–environment), to which the discussed transport system, being the research object of this work, belongs as well. Basing on the author's own research and the identification of processes occurring within the studied object, a method and a model for its operation quality assessment have been developed and discussed in the article. Application of the method enables making an assessment of the research object operation quality, depending on changes of values of features describing the actions of operators, technical objects operated by them and the impact of the environment.
Podstawą działania systemów eksploatacji jest realizacja postawionych im celów w określonych warunkach, miejscu, ilości i czasie. Ocena jakości ich funkcjonowania stanowi zbiorczą miarę zarówno pod względem efektywności, niezawodności, bezpieczeństwa, ekologiczności, jak i ergonomiczności. Z analizy literatury przedmiotowej wynika, że badanie jakości funkcjonowania tych systemów stanowi jeden z podstawowych czynników w procesach obsługowo-naprawczych, sterowania, zasilania, diagnozowania, a w szczególności użytkowania eksploatowanych w nich maszyn i urządzeń. Omawiane systemy zalicza się do systemów socjotechnicznych typu (człowiek–maszyna–otoczenie), wśród których wyróżnić można system transportowy, stanowiący w niniejszym opracowaniu obiekt badań. Na podstawie wyników własnych badań eksploatacyjnych oraz identyfikacji procesów realizowanych w obiekcie badań w opracowaniu przedstawiono metodę oraz zbudowano model oceny jakości działania takich systemów. Zastosowanie tej metody umożliwia ocenę jakości ich działania, realizowaną w zależności od zmian wartości cech opisujących działanie operatorów, sterowanych przez nich obiektów technicznych oraz wpływu otoczenia.

Opis:: Selection and determination of assessment criteria is of great importance for evaluation of the system operation quality. The analysis was made within the research on operation quality of a selected transportation system. This was a real system, operating purposefully, providing passengers with transport tasks, over an assigned urban area and suburbs, according to an established schedule. Such a system of operation is affected by the behaviour of people, functioning of transport means and the environmental impact. On the basis of performed tests, a set of criteria, whose fulfilment degree is crucial for functioning of the analyzed system, has been determined. It must be remembered, though those particular criteria are diversified in terms of their significance for the transportation system assessment. Therefore, the analytic hierarchy process AHP has been applied in this work, in order to establish significance of particular criteria, from the point of view of the set quality requirements for the studied transportation system. The analytic hierarchy process has been used in the papers concerning the problems of quality control and assessment of transportation systems. It is one of several tools supporting the process of selection of the most significant criteria aiming at reduction of the considered vector dimensionality and establishing a set of features, accepted for an assessment of the research object operation quality, while building the resultant model.
