摘要
[目的]为建立道路交通噪声预测和应用系统提供基础数据.[方法]运用GIS空间分析中的Kriging插值方法与RLS90模型相结合对城市交通道路噪声进行模拟预测,通过RLS90模型的声源模型与声传模型计算道路噪声值,运用Kriging插值方法进行空间模拟,对道路噪音未知样点进行线性无偏最优预测,并以湖南省长沙市芙蓉区雍景园典型小区为例,进行了验证.[结果]实例应用结果表明,长沙市芙蓉区雍景园小区5个测量地点的噪声预测值(67.40 dB)与测值(66.26 dB)的空间分布和传播趋于一致.[结论]Kriging插值方法与RLS90模型相结合可以运用于道路交通噪声的实时预测和决策.
Abstract
[Objective] To provide basic data for the prediction and application system of traffic noise in roads.[Method] Simulating prediction of traffic noise in urban roads was carded out by Kriging interpolation method and RLS90 model in GIS spatial analysis.Road noise value was calculated by sound source model and sound transmission model in RLS90 model; spatial simulation was carried out by Kriging interpolation method ; linear unbiased prediction was adopted by the unknown sample sites of road noise.With a given community in Furong District,Changsha City,Hunan Province as an example,verification test was carried out.[Result] Spatial distribution and transmission of noise prediction value (67.40 dB) and measured values (66.26 dB) tended to be uniform in five measuring sites of Furong District.[Conclusion] Combining the Kriging interpolation method with RLS90 model can be applied in the prediction and decision making of road traffic noise.
