The purpose of the article is to deepen the considerations on smart mobility. It is a solution pursued by all cities around the world. The publication presents the current ranking of major cities of the future and is provided with adequate commentary. Attention was also paid to the need for scientific exploration in the context of new emerging challenges surrounding fleet modernization and diversification of environmentally friendly propulsion sources. In the case study section, the author analysed how the local government unit met the qualitative and functional challenge of public transportation for residents. The subject of the study was the capital city of Warsaw. The author presents a brief picture of the city and, according to available data, discusses the possibilities of technological modernisation of the available rolling stock and outlines the changes in the use of conventional fuel and environmentally friendly alternative energy sources. Based on the study, it has been concluded that the direction of development of the capital in the whole area of smart cities, as well as in the sphere of the mobility index, improve the comfort of travel in the agglomeration area.

The article presents the process of changes in the structure of the tram transport fleet in Poland from the moment of joining the European Union, i.e., from 2004, to 2022. Basic information about Polish enterprises providing tram transport was presented. The structure of passenger rolling stock in individual cities was described. The author attempted to discuss and define the basic processes related to the changes in the structure of the rolling stock and to present statistical data covering the period in question. This issue was analysed on the example of 15 Polish tram transport systems (along with the description of the process of financing with EU funds). The main aim of the article was to show the dynamics of changes in the rolling stock structure in individual tram companies in Poland. [ABSTRACT FROM AUTHOR]

This paper is devoted to the development of an effective system for monitoring the technical condition of the axle boxes of rolling stock. To this end, the possibility of solving problems of fault diagnostics based on the theory of fuzzy sets is considered. This allows one note such difficult-to-formalise factors as experience and intuition of a highly qualified expert specialist. It showed that an expert system-based monitoring approach allows evaluation of the technical condition of the axle boxes, characterised by internal and external operating uncertainty. It also proposed the use of parameters such as vibration and noise for comprehensive monitoring of the technical condition of axle box units together with temperature. Furthermore, the combination of these diagnostic parameters and expert system’s possibility to receive all necessary information about the condition of the most critical components of the axle boxes in real-time and analyse the changes in their operational parameters was explored. The stages of modelling an expert system in the Fuzzy Logic Toolbox package of the MATLAB computing environment are presented.
