影响高速公路交通噪声预测关键参数
Key Influencing Parameters for Traffic Noise Prediction of Highways
摘要
Abstract
Vehicle flow flux, vehicle type ratio and vehicle speed are key parameters for traffic noise predication. Based on the investigation of a typical highway in Sichuan province, road traffic noises in different monitoring areas were predicted adopting the method recommended by the“Technical Guidelines for Noise Impact Assessment (HJ 2.4-2009)”. Through the mutual comparison between the predicted values and the actual monitoring ones, it can be concluded that (1) the traffic noise predicted by using either design speed or actual speed is close to the measured traffic noise;(2) the result choosing the measured speed and taking the entire highway as a whole can forecast the traffic noise better than the other lane-group strategies;(3) the result using the vehicle-type-ratio measured at night can predict the night traffic noise more accurate-ly than that employing the vehicle-type-ratio measured in the daytime.关键词
