Three-Dimensional Traffic Noise Propagation to Buildings with Atriums or Annexes by Using the Beam Tracing Method

Buildings with atriums or annexes are common in urban areas. However, the traditional beam tracing method can’t deal with these kinds of situations directly. In order to simulate traffic noise around buildings with atriums or annexes, this paper presents a traffic noise simulation model which is based on beam tracing method and triangular-prism space subdivision. Firstly, the paper presents the data structure for buildings with atriums or annexes, so these two kinds of buildings could be recognized by the simulation model. Then, the model divides the whole area into triangular-prism subspaces, according to the building shapes. Finally, the traffic noise propagation around buildings with atriums or annexes is simulated by using beam tracing method. Examples are given at the end of the article and prove the method to be effective.
