摘要
阐述城市道路交通噪声高污染区域的监测与模拟研究。实现基于微观交通仿真的交通噪声动态模拟方法,采用该方法对峡谷型道路十字交叉口和公交车站两类典型的城市道路交通噪声高污染区域进行了动态模拟,同时对这两类区域的交通噪声进行了实地监测。监测结果和模拟结果的对比表明:该方法对等效声级Leq和统计声级L10,L50和L90等的预测具有较高的准确性,对交通噪声实地监测的优化布点和区域噪声分析有较强的指导意义。
This article presents the monitoring and simulation research of high pollution area of urban road traffic noise. The research implements a dynamic simulation method of traffic noise based on microscopic traffic simulation. Along with the field monitoring of two types of typical high pollution area, the intersection of canyon-type road and bus station, the sim- ulation has been done by using this dynamic simulation method. Comparison of results between monitoring and simulation in- dicates the predictive accuracy of equivalent sound level of Leq and statistical sound level of L10, L50, L90. This method can help site selection of field monitoring and area noise analysis.
