摘要: 在城市环境噪声排放模型及噪声传播模型的基础上,考虑建筑物群及林带对噪声的衰减影响,并结合地理信息系统(GIS)研发了城市环境噪声模拟与评估系统—“中大声图”。系统搭建了点线面环境噪声的排放模型和传播模型,特别在线声源道路交通噪声方面,利用GIS获取道路与建筑物信息,加载车辆排放模型,计算了城市尺度的道路交通噪声分布,并利用计算结果在GIS上绘制出交通噪声地图。最后将系统应用于城市交通噪声的模拟和减噪效果评估上,结果表明该系统的算法准确有效。

Abstract:

Using the urban environment noise emission and propagation model,also considering the attenuation impact of buildings and tree belts on noise , an urban environment noise simulation and evaluation system named “Zhong Da Sheng Tu” was developed with the help of geographical information system(GIS). The noise emission,propagation model of point, line and plane source were set up in the system. As for the traffic noise of line source, GIS was used to obtain the information of roads and buildings. The road traffic noise distribution of urban area was calculated with the vehicle noise emission model. The calculation results were imported to GIS to make the traffic noise map. At last, the system was used to simulate the urban traffic noise and evaluate the effect of noise reduction measures, results show that the systems algorithm is accurate and efficient.

Key words: road traffic noise, simulation and evaluation system, geographical information system, noise map
