摘要
将摩托车流单独处理,通过理论推导和实测数据回归建立摩托车为主的道路交通噪声预测模型.模型对居住区的交通噪声(Leq)预测精度在 2.5dBA 以内,道路两侧 Leq预测精度更高,大部分测点误差在 1dBA 以内.
Analyzing motor cycle flow separately, traffic noise prediction model of motorcycle mainly was established through theory inference and actually measured data regression. The prediction made precision traffic noise Leq of inhabiting region was within 2.5 dBA, the Leq prediction precision for roadside noise was still higher, with error of greater part of prediction point within 1 dBA.
