    One of the major problems of transport systems is the movement organization without catastrophes. It is particularly important for the rolling stock of the river fleet. In this paper, the authors propose the evaluation method of the technical condition of inland waterway vessels on the statistics of accidents and disasters of previous navigation. The method is based on the statistics for the small samples

    Article presents the impact of anthropogenesis on the aquatic ecosystem of the Brda River estuary. Studied section is part of the E-70 international waterway, which is connecting Central and Eastern Europe. This small section of the Brda River has very unique character, due to the hydrological transformations during the nineteenth and twentieth centuries by human race. They were happening in the “adaptation of the Brda River to the inland waterways.” They were consisted in the construction of Brdyujście sluice. New hydrotechnical building created artificial water reservoir, which was used for recreational purposes, as the Regatta Track. Damming of the Brda River significantly changed water flow regime in this section. Flow has been slowed and has given nearly limnical nature to the estuary section of the Brda River. This is reflected in the transport of suspended material (total suspension) and the rate of the sedimentation in reservoir. Soundings of the bottom indicated varied thickness of the sediments. Subsequent hydrological changes in the analysed section of the Brda River, occurred at the time of closing the Brdyujście sluice and opening new inland waterway crossing to the Vistula River – Polish Czersko sluice. In this way, a significant part of the waterway (regatta track) was eliminated from the use. These changes are adversely affecting on functioning of the whole research part as an inland waterway. The dredged treatments serve not only providing proper conditions for a sporting event on the Regatta Track, but also should contribute to the improvement of navigation in this part of the Brda River. The research of the concentration of selected elements indicated the spatial variation in the rate of sediment accumulation processes. Based on available data, it is possible to propose dredged treatments as an element that enables the possibility of shipping on the Brda River section to remain at the same level.

    The article discusses a new approach to the detection of GNSS spoofing, based on the use of satellite compass. Comparing the results of measurements of GNSS receivers of compass in two modes (normal mode of GNSS navigation and spoofing mode). The studies have shown, that in mode of spoofing attacks in both receivers of satellite compass we have the equality of coordinates, which in algorithm coordinate definitions, determine mathematical indeterminate form 0/0. This means getting out of the operating status of the satellite compass that can be used as an alarm “spoofing attack” to take appropriate security measures of GNSS navigation.

    The paper presents several issues concerned with safety of inland ships navigation in Szczecin Port area. Additionally the analysis of inland ships movement has been performed which is necessary to full picture of safety analysis. The problems related with safety of inland ships on the area of deep sea ports is often omitted in safety analysis, which could be the reason of lowering safety level or neglecting important issues related to port safety.

    The main aim of the article is to present the importance of tourism in Polish regions within the Central European Transport Corridor CETC ROUTE 65. Four of Polish voivodeships (West Pomeranian, Lubusz, Lower Silesia and Opole) are signatories of CETC ROUTE 65. The tourist accommodation and its occupancy are examined, as well as tourist traffic in these four provinces. The analysis of tourism in the West Pomeranian region is the result of research, done under the development project titled ‘Research on and modelling of mode-integrated transport system in the West Pomeranian region with a focus on the Central European Transport Corridor North – South CETC ROUTE 65’, financed by the National Research and Development Centre in the years 2009–2011 and research project “Port logistic centres as stimulants of the development of ports, port towns and seaside regions. Research, modeling, concept of location, operations and management”, financed by the National Science Centre in the years 2011–2012. The research was co-ordinated by Czesława Christowa at the Maritime University of Szczecin.

    The authors present the method of assessing the percentage of coverage of surface of the river by ice occurrences. This article concentrates on image analysis methods applied to assess the percentage of coverage of a waterway by ice occurrences. A decision, whether to stop navigation depends on an accurate calculation of amounts of ice floe and overall atmospheric conditions. For this purpose closed-circuit video camera images converted with the use of a set of edge detecting filters and subjected to quantitative analysis have been used. The correct assessment of ice occurrences may positively influence the navigation itself, as well as help in planning the use of inland waterways in transportation process.

    Inland waterways vessels operate in waters of restricted depth and restricted width with cross-section of the waterway of different profile. These conditions affect hydrodynamic forces acting on the vessel and in consequence they affect their operation. There are several hydrodynamic effects present in inland waterways. Restricted depth and cross section of the canal or river affects resistance of the vessel and hydrodynamic characteristics of the propeller and in consequence propulsive efficiency. Another effect is caused by modification of pressure distribution around vessel body resulting in change of draft, so called squat. Finally in narrow fairway lateral forces on the vessel are created and in case of non-symmetrical position of the vessel, those forces are also non-symmetric and causing that the vessel is pushed to one side. This affects safe handling of the vessel and requires understanding and skill of operator. This problem is discussed in the paper.

    Transport of goods is of great importance in socio-economic life of societies. In Poland, where the power industry is based partially on bituminous coal extracted in mines of Upper Silesia, the transportation of coal is of great significance. The coal transportation acquires special importance in the corridor of the Odra River, where the Power Station Opole, Kogeneracja Wrocław, industrial complex of Power Station Dolna Odra, and numerous other industrial companies, that rely on such energy carrier are located. Location (intentional) of coal consumers, as well as historical determinants, created the chance of functioning of alternative transport systems: rail and inland waterborne ones. Intuitive interest in inland waterborne transportation as mass transportation that is cheaper and safer for natural environment, is the subject of present paper. Main objective is the presentation of the method for evaluation of so-called external costs in multimodal transportation of coal including the non alternative rail transport between coal mines and the port of Gliwice, and inland waterborne transportation from the port of Gliwice to the consumers located by the Odra River.

    The article presents a selection of topics concerning inland freight transport. It is part of the European transport system that holds different places in the transport system of every country. At the same time it is an element of their water management system. Therefore, the development of inland shipping is influenced by two key factors. The first one is the adjusted natural water system, which as a linear system, enables freight transport. The second factor is water management policy, which takes into account inland shipping in the water resources management. In many European countries, especially in the Netherlands, Belgium, Germany and Rumania, barge freight transport is a part of these two systems. Inland shipping in the European overland transport engages in approximately 6.5% of the transport activity by carrying dry, liquid, general and containerized bulk cargo. It is of significant importance to the international cargo transport in many European countries – adjusting techniques and organization of transport to constantly changing requirements of the shippers, which results from the shift in the industry structure in Europe. It is no longer associated with transport of coal and iron are only, although they still make the primary freight in inland shipping. The ro-ro barges carry containerized and palletized cargo and are components of the multimodal transport chains.

    For disintegration process control we need a quantity that respects objectively rock-disintegrating tool interaction with the elimination of human factor. From this, basic requirements for the evaluation quantity given below follow: is available in advance or at the moment of disintegration; minimises the influence of human factor on the resultant effect; evaluates objectively the disintegration process. A measure of efficiency of any disintegration process is the consumption of energy usually related to the unit volume of disintegrated rock; on the basis of analysis done theoretical and practical researches orientated towards the disintegration processes and the verification of objectivity when used in situ (in drilling and tunnelling), at present it is minimised specific volume energy that is the most objective evaluation quantity. This quantity has a general validity for dispersion processes, and thus its use even for the evaluation of diggability on the digging wheel of excavator has a rational basis. In connection with the GIS application for controlling the extracted quantity, an optimal tool is offered for the maximum efficiency of excavation process.

    The article discusses the problem of computer aided decision making processes in inland waterway transport. Inland waterway transport is of minor importance in the Polish transport system. One of the reason for this is the difficulty in making decisions about transportation. This is due to the high variability of navigational conditions on Polish waterways, thus the low reliability of this mode of transport. This does not change the fact that the inland waterway transport of bulk goods, oversized and hazardous materials is the most efficient and least burdensome means of transport. For this reason, one should aim to increase the share of freight with the use of inland vessels. The paper indicates the possibility of supporting decision making processes in the organization of inland waterways transportation. For shippers or other persons organizing transport of goods, various issues can be important: the cost of transportation, delivery or handling method. Often, due to the lack of appropriate tools transportation is directed to the cars. Access to appropriate computer programs that calculate of the some parameters for the carriage or optimization criteria, may increase the use of inland waterway transport, and consequently a reduction in external and social costs, associated with carriage of cargo. The paper describes the possibilities.

    Problems of sustainable economic development also apply to urban transport. The European Union emphasizes the creation of a sustainable transport system in which public transport will function more efficiently. Currently not all possible means of transport are used in public transport. Attempt to introduce transport water means in public transport does not always have a successful result. Existing solutions do not fully meet the postulates requested in passenger transport. The article analyzes the main technical and financial conditions and makes proposals necessary for the implementation of water public transport. Special attention in these proposals is paid to Szczecin agglomeration.

    Socio-economic development creates a lot of problems and challenges. At various levels, these problems are different, for example: globalisation, generating increased demand for transport, presents new challenges for transport, especially international; increasing disparities in regional development, as a source of social problems, make it necessary to look for more effective ways of eliminating these disparities; problems of towns and large cities, associated amongst other things with the growing needs of transport and insufficient infrastructure, reduce the standard of living and require an urgent solution. Contemporary socio-economic problems have significant impact on transport, but on the other hand through changes in transport, many of them can be partly solved. This article aims to analyze the possibilities of developing inland waterways to solve today’s social and economic problems.

    The European Commission adopted a comprehensive strategy for a competitive transport system that will increase mobility, remove major barriers in key areas and fuel growth and employment. At the same time, the proposals will dramatically reduce Europe's dependence on imported oil and cut carbon emissions in transport by 60% by 2050 [1]. Inland waterway transport offers an environment friendly alternative in terms of both energy consumption and noise and gas emissions. Financing of inland waterway transport infrastructure is one of the most important barriers that prevent its increased use. The investment in inland waterways in Poland and Germany does not reflect the real needs. Experience of the countries in the implementation of transport policies shows that a clear specification of investment priorities and consistency in their implementation promotes economic efficiency.
