Abstract
This paper models the dynamic traffic noise in elevated road and analyzes the impact of traffic noise on nearby buildings under various conditions. Combining microscopic traffic flow simulation technique, vehicle noise emission levels and noise propagation attenuation principle, the dynamic traffic noise simulation model for elevated road is established. And the instantaneous equivalent sound level and statistical sound level are calculated. The vertical and horizontal acoustic fields of the elevated road are simulated. The impacts of multi-lanes, vehicle speed, traffic volume, height of sound barrier and tree belt on the traffic noise level of the elevated road are analyzed. Also, the impact of traffic noise on different floors of buildings along the elevated road is analyzed. This work may provide a reference for traffic control, speed-limiting, sound barrier constructing and tree belt planning.关键词
