    Opis:
    The aim of this paper is to identify and quantify the direct economic effects resulting from navigational restoration of the Dąbie Lake inland fairway, a part of the West Pomeranian region (PL) transport system that runs across the Dąbie Lake. This narrow and shallow inland fairway constitutes the bottleneck for inland waterway freight transport, which must therefore use the sea fairway and thereby incur extended time, increased cost, and reduced efficiency of inland waterway transport. The paper’s second section presents the transport and microeconomic effects that restoring the fairway’s navigability across Lake Dąbie would have on the inland navigation system, thereby increasing the capacity, effectiveness, and safety of inland waterways freight traffic. Restoration of the inland fairway would significantly reduce generalized and external costs of inland waterways transport.

    Opis:
    This study aims to identify and quantify the economic benefits of eliminating collisions between two transport systems: rail and inland waterway transport. The collision between transport systems is caused here by the obsolete structure of a railway drawbridge, which constitutes an element of the railway line used by freight and passenger transport and is located on the main inland waterway used by inland waterways freight transport. Railway transport results in limitations of inland waterway transport and, vice versa, inland waterways transport blocks railway transport during lifting of the bridge span. In the case of railway transport, the low capacity of the single-track railway bridge constitutes an additional limitation of the development of transportation. There are plans to eliminate the collision in the regional transport system by constructing a new railway bridge in place of the old drawbridge. The effects of the transportation infrastructure improvement were measured directly for both rail and inland water freight systems as well as the result of the interaction between passenger rail and car and bus transport. In order to compare the different types of impact, the effects of different actions were valued in monetary terms. The planned intervention, as investigated here, will lead to reductions in the cost of time of inland waterways freight transport and costs of time of rail passenger and freight transport and a decrease in the external costs of transport. This will make possible transportation services that are both cheaper and more reliable.

    Opis:
    The aim of the article is to analyse the similarities between the selected European countries in terms of time allocation. Time allocation has been defined as the daily distribution of time to various activities. Professional work time, domestic work time and leisure time are the most important for the economic approach. It has been proved that there are coherent groups of countries with similar structure of time allocation. The taxonomic methods used in order to verify the thesis included: cluster analysis, k-means method, generalised distance measure GDM and interval taxonomic method TMI. The analysis was performed on the basis of HETUS data.
