Abstract
Urban trains and subways are a Brazilian reality. One aspect that is delegated to the background, concerns the quality transportation referred to availability, capacity and safety. Lately, vibration and noise produced by this means of transport have been affecting life quality of surrounding areas as the comfort of the users. In this paper, the whole body vibration levels in urban trains in Porto Alegre (Trensurb) are evaluated in some situations. The vibration dose value and rms acceleration, when compared to standards, showed very low values. Those values were measured at the seatback, seat and floor of the train seats at some points inside the vehicle and it was found below the action limit (0.5 to 1.1 m/s²) and far from the exposure limit. Generally speaking, the measured vibration levels are considered comfortable, however in some positions and situation they can be considered uncomfortable.
