摘要
基于微观交通流仿真,结合ASJ-RTN 2008单车噪声排放模型,研究驾驶员行为对交通噪声的影响。通过敏感性分析得知,拥堵状态下的交通噪声对驾驶员跟驰行为和信号反应较为敏感,其中跟驰行为对交通噪声影响高达2.07 dB;而在畅通状态下,驾驶员行为对交通噪声的影响极小。受驾驶员行为变化的影响,区域噪声排放总能量与路旁LAeq值的变化趋势相似,单位出行里程噪声排放能量与路旁LAeq值的变化趋势相反。
Based on the driver＇s behavior model of the microscopic traffic simulation system and the road traffic noise prediction model by the Acoustical Society of Japan, the influence of driver＇ s behavior on traffic noise was studied. The sensitivity analysis showed that the road traffic noise in congested condition was sensitive to the driver＇ s follow behavior and the driver＇ s reaction to the traffic signals, of which the driver＇ s follow behavior could contribute 2.07 dB to the traffic noise. While in non-congested condition, driver＇ s behavior had little influence on traffic noise. It was shown that the influence of the driver＇s behavior on noise emission energy in the whole area is similar to the value of L Aeq by the roadside, nevertheless the influence of the driver＇ s behavior on noise emission energy measured in unit trip distance appears contradict to the value Of LAeq by the roadside.
