EN In the recent years the directions of development of urban transport in European cities in-dicate development of tram systems. The consequence of growing trams participation in city traffic is a significant impact on the vibroacoustic climate of urbanized areas. The undesirable effects are the result of a dynamic interaction in tram-track system. This state causes needs to take measures for the proper functioning of trams, ensuring trouble-free and comfortable ride for passengers from the noise and vibration point of view. Most of all these activities should be associated with proper cooperation of trams and tracks, not only to ensure their proper technical condition, as confirmed by recent studies. The article presents problem of optimization transport process from the point of view the vibroacoustic effects, which are additionally complicated by different types of vehicles and track construction in one tram network. The presented studies contain experimental results of this problem under normal trams operation on the infrastructure in Poznan (PL). The issues re-late to the comparative analysis paraseismic vibration as the effect of dynamic tram-track im-pact. The phenomenon was observed during pass-by tests of one selected tram type on three track sections with described dynamic response.
