| Abstract: | A traffic noise calculation model about street canyon road intersection was built by applying geometrical acoustics theory.In this model,three kinds of sound transmission route among buildings,including perpendicular incidence,reflection and diffraction,were considered.Taken measured data of traffic volume,proportion of vehicle types,etc.as inputs,and combined this model with microscopic traffic simulation,the traffic noise at a street canyon road intersection was simulated.The comparison between simulated ... |
