The invention relates to the technical field of traffic noise source intensity prediction, particularly to a road shoulder-based road traffic noise source intensity prediction method. The invention aims to solve the problem of large deviation between a predicted value and a monitored value of an existing road noise source intensity prediction model. The invention discloses a road shoulder-based road traffic noise source intensity prediction method, which comprises the following steps of recording flow values and current speed values of various types of vehicles of a target road in a preset time period and proportions of various types of vehicles, and then calculating an average speed value of the various types of vehicles; and substituting the total flow value and the average speed value of various types of vehicles and the proportion value of various types of vehicles into a road noise source intensity prediction model, and calculating to obtain the noise source intensity value of thetarget road. The prediction method can play an important role in environmental influence evaluation, sound barrier design and urban noise map drawing.
本发明涉及交通噪声源强预测技术领域,更具体地说,涉及一种基于路肩的公路交通噪声源强预测方法。本发明专利目的在于克服现有的公路噪声源强预测模型的预测值和监测值偏差大的问题。本发明公开了一种基于路肩的公路交通噪声源强预测方法,其过程如下:记录目标公路在预设时间段内的各类型车辆的流量值、当前速度值以及各车型车辆的比例,然后计算所述各类型车辆的平均速度值。通过将各车型车辆的总流量值和平均速度值以及各类型车辆的比例值代入到公路噪声源强预测模型中,计算得到目标公路的噪声源强值。该预测方法可在环境影响评价、声屏障设计、城市噪声地图绘制中发挥重要作用。
