摘要
根据实测所得交通流量和车型分布 .采用预测为主、实测为辅的方法对典型居住小区进行了交通噪声预测 .应用噪声冲击指数法对小区交通噪声进行总体评价 .在分析小区交通噪声的时间分布特征和空间差异的基础上 .提出小区噪声环境的防治对策 .
Road traffic noise in a sample housing estate was calculated in detail using prediction method. Traffic noise in this housing estate was assessed using Noise Impact Index (NII). Considering temporal and spatial distribution of traffic noise in this housing estate, noise mitigation measures were supported and evaluated. Findings from this study are potentially useful in traffic noise assessment and mitigation of urban housing estate.
