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:: The analysis of results of experimental tests and a literature survey of the issue reveal that the subject matter connected with determination of the optimal number of a given transportation system operation assessment criteria has a direct influence on the result of the considered assessment. The analysis was made within the research on operation quality of a selected transportation system. In order to optimize the analysed system assessment criteria, a theoretical description has been made and an example of canonical correlations application has been presented. Analysis of canonical correlations involves determination of linear combination parameters of the studied sets so that the obtained correlation coefficient will have maximal value. In the successive step, the next pair of linear combination are not correlated with the combinations determined in the first step. The determined correlations can measure the power of relation between two sets of variables and are useful in the process of choosing significant criteria for a given research object operation quality assessment.

Opis:: The analysis of results of experimental tests and a literature survey on the issue reveal that the subject matter connected with determination of the optimal number of a given transportation system operation assessment criteria has a direct influence on the result of the considered assessment. Whole study has been made on the basis of the analysis of data obtained from tests performed in a real municipal transportation system, providing transport tasks in a 400 thousand urban agglomeration. On the basis of the tests, there was determined a set of sixteen criteria for the system operation assessment, depending on preferences of drivers, passengers, workers of the system providing vehicles with serviceability and the last group of results is a final assessment. The research involved tests of significance for correlation coefficients between the assessment criteria. The method of main factors involving analysis of a linear transformation of existing vector of variables X into Y has been used to study the task dimensioning. Proper values, providing basis for determination of a new space correspond to coordinates of the newly created vector Y. On this basis, the dimension of the criteria and their significance space has been concluded. The determined criteria have been accepted for the development of a resultant model for assessment of a transportation system operation quality.

Opis:: An analysis of experimental tests results and a literature review show that determination of the optimal number of criteria for assessment of operation quality of a given transportation system is crucial to the assessment result. The analysis has been performed on the basis of research on operation quality of a given transportation system. This is a real transportation system providing the population with transport services in a given urban and suburban area. The operation quality of such a transportation system is affected by people's behavior, operation of the vehicle, and the impact of the environment. In order to ensure appropriate quality of the system functioning it needs to be constantly evaluated. The transportation process ought to be optimized and innovative solutions should be implemented. In this work a set of evaluation criteria has been determined, on the basis of which, evaluation and analysis of the quality of transport services provided by a given municipal transportation system have been performed.
Analiza wyników badań eksploatacyjnych oraz literaturowy przegląd zagadnienia wykazały, że problematyka wyznaczania optymalnej liczby kryteriów oceny jakości działania danego systemu transportowego jest istotnym zagadnieniem, mającym bezpośredni wpływ na wyniki realizowanej oceny. Całość rozważań dokonano w ramach realizowanych badań dotyczących oceny i sterowania jakości działania wybranego systemu transportowego. Jest to rzeczywisty, działający celowo system, świadczący usługi przewozu pasażerów na określonym obszarze miejskim i terenach podmiejskich. Na jakości działania takiego systemu ma wpływ działanie ludzi, funkcjonowanie środków transportowych oraz oddziaływanie otoczenia. Zapewnienie oczekiwanego poziomu jakości świadczonej usługi transportowej powinno być związane z ciągłą jego oceną, optymalizowaniem procesu transportowego oraz wprowadzeniem innowacyjnych rozwiązań. W niniejszym opracowaniu wyznaczono zbiór kryteriów ocenowych i na ich podstawie dokonano oceny oraz analizy poziomu jakości usług przewozowych świadczonych przez wyróżniony system transportu miejskiego.
