In order to obtain the distribution pattern of noise along the tram line, the typical operating section of Dalian Tram 202 line was selected as the research object. The noise along the line was predicted theoretically and simulated, and the noise in this section was measured on site. The theoretical, simulated, and measured values were compared. When the tram passes through, the noise on both sides of the line exceeds 70 dB (A). On the side close to the tram, the tram noise plays a decisive role, while on the side far from the track, the tram noise and road traffic noise work together. When there is no tram passing through, the traffic noise on both sides of the road is below 70 dB (A). This indicates that the operation of the tram will have an impact on the buildings along the line. In theoretical calculations and simulation predictions, the noise of trams is relatively low, while the noise of road traffic is relatively high. This may be due to the fact that the sound source of trams is far away from the sound receiving point, and the running speed of road vehicles is higher than the actual running speed.
