　　首先对研究路段车流量、车速等交通流数据进行实测并拟合得出它们服从的分布规律。然后运用Monte Carlo仿真产生服从相应分布规律的多组交通流数据，进而运用微观交通流仿真技术对道路设置外侧式和不设置公交专用道两种情况进行仿真，对仿真数据运用单车噪声排放模型和噪声传播模型计算出观测点的噪声及其分布规律。对观测点噪声进行统计分析表明，与不设置公交专用道相比，道路设置外侧式公交专用道时，观测点噪声均值、不确定度和污染级均有明显的增加。

The distributions of traffic volume and vehicle’s velocity were obtained by curves fitting of measured traffic data. Simulations of curb bus lanes and unset bus lanes were conducted by using microscopic traffic simulation based on the traffic data generated by Monte Carlo simulation according to the distribution laws. Noise at the monitoring points was calculated using noise emission model and propagation model of a single vehicle. The statistical results show that when curb bus lanes are set, the noise mean value, the noise uncertainty and the noise pollution level increase apparently in comparison with the case without bus lanes.
