This paper presents the concepts of a new tram quality measure: vibroacoustic activity. It is based on a complex phenomenon occurring during tram ride in real operating conditions, by taking into account different technologies and the technical state of the tramway infrastructure and the differences in construction of the selected tram types. The methodology of the experimental research and basic remarks on those are also presented. At the core of the experimental research it was assumed that changes in the technical state of riding units (bogies) are the main changes in the vibroacoustic activity of the tram. These changes are possible to observe and recognize in a pass-by test. In this study, multi-faceted analysis of the impact of a tram type on the results was performed. The collected experience allowed the preparation of a concept tram operation support system. This paper presents the methodological basis for developing a monitoring system of vibroacoustic activity level of a tram under urban operational conditions. The project is implemented and developed with cooperation of the local tram operator (MPK Poznan) and the Urban Transport Authority of Poznan as a complementary solution to the on-board technical state monitoring system, developed by the authors within the MONIT project.
