【摘要】：對山東省濟南-菏澤高速公路的部分路段進行交通噪聲24 h連續(xù)監(jiān)測,并根據(jù)實測的交通量和車輛行駛速度,運用FHWA模型、RLS90模型和規(guī)范模型進行噪聲預測,將實測值與預測值進行對比分析可知,規(guī)范模型的預測值準確性更強.對高速公路單車噪聲源強進行進一步實測分析,結果表明規(guī)范模型的源強計算值和源強實測值比較接近.考慮優(yōu)化車型分類方式,將未滿載的大客車歸為中型車進行噪聲預測,可使規(guī)范模型噪聲預測值更為準確.
[Abstract]:The traffic noise of some sections of Jinan-Heze Expressway in Shandong Province was continuously monitored for 24 hours. according to the measured traffic volume and vehicle speed, FHWA model, RLS90 model and standard model were used to predict the noise. The comparison between the measured values and the predicted values shows that the predicted value of the canonical model is more accurate. The noise source intensity of expressway bicycle is further measured and analyzed. The results show that the calculated value of the source intensity of the code model is close to the measured value of the source strength. Considering the optimization of vehicle classification method, the noise prediction of the standard model can be more accurate by classifying the underloaded buses into medium vehicles for noise prediction.
