运用SoundPLAN软件，以南京市城市道路现状为基础，利用我国声环境导则中的道路噪声预测模式，建立了普通城市道路（非高架、隧道等）噪音预测通用模型。并根据实际需要，选择影响噪音的主要因素（车流量、车速、车道数、车型比），利用通用模型分析这些交通管制因素对道路噪声的影响。分析结果表明：噪声随交通量的增加而增加；随车速的增加，噪声先缓慢降低后快速直线增加；随车道数的增加，噪声有所增加，且离道路中心点越近，噪声的增幅越大；随大型车比例的增加，噪声增速变慢。通过该研究可得到各种交通管制因素对噪声变化的影响，并能为城市道路噪声的预防和控制提供一定的依据。

Considering the current urban roads situation of Nanjing,the noise prediction universal model in the ordinary urban roads (not viaduct or tunnel)is first presented with SoundPLAN accord-ing to the noise prediction model in the national acoustic environmental guidelines.Based on actual demands,the influencing factors such as vehicle flow,vehicle speed,road path number,vehicle types are mainly considered,and then the influence of them on noise is analyzed.The analysis re-sults show that the noise increases with the increase of vehicle flow;the noise first slowly decreases then linearly increases with the increase of speed;the noise increases with the increase of the road path number,and increases more when closer to the road center;the rate of noise increase becomes slow with the increase of the proportion of large vehicles.Therefore,by the research,the influence of various traffic control factors on the noise can be obtained,which provides a basis for prevention and control of urban road noise.
