摘要

采用微观交通仿真对居住小区的道路交通噪声进行动态模拟研究。用微观交通仿真技术进行路网的建模及车辆的动态交通仿真,结合车辆噪声的排放模型以及噪声传播模型,考虑了噪声在建筑物间的反射和衍射,实现了对居住小区在路网用户均衡和非均衡条件下的交通噪声动态模拟,分析了新增道路穿越小区对小区噪声的影响,模拟了不同建筑物布局下居住小区交通噪声的声场分布。通过道路交通噪声的动态模拟不仅得到了小区噪声的等效连续声级,还掌握了其波动起伏特性。最后,进行了实地的交通与噪声监测,实测与模拟结果对比表明该方法精确可行。

Abstract

Microscopic traffic simulation was used to simulate the dynamic road traffic noise for housing estate. Route network was modeled and vehicle dynamic traffic was simulated by microscopic traffic simulation technology. Combining with the vehicle noise emission model and noise propagation model which considered reflections and diffractions among buildings, the dynamic traffic noise simulation for housing estate in networks of user equilibrium and unbalanced conditions were realized. The influence to the traffic noise field distribution was analyzed when building a new road through the housing estate and positioning the different building layouts. The outputs were not only the spatial distribution of traffic noise for housing estate, but also the temporal one which can reveal the fluctuation characters of road traffic noise. At last, the measurement results of field survey agreed well with the simulated ones.
