Abstract
This study addresses the applicability of traffic noise prediction models under high traffic flow conditions.Noise monitoring was conducted within a 300-meter radius on one side of the Chengdu Ring Expressway.By comparing predictive methods from the TNM3.2 model,JTG B03-2006 standards,and HJ 1358-2024 standards,it was found that the measured noise energy mainly concentrates within the 630-2000Hz frequency band,with significant peaks at 63Hz,800Hz,and 1000Hz.The results indicate that the TNM3.2 model exhibits an average prediction deviation of 5.6dB(A)across the entire monitoring area,while the HJ 1358-2024 standard achieves higher prediction accuracy within 200 meters,with an error range of 0.4-2.0dB(A).The JTG B03-2006 standard performs best in the 200-300 meter zone,with errors between 0.3 and 0.9dB(A).These findings provide empirical support for selecting appropriate traffic noise prediction models under high traffic flow conditions and offer valuable references for urban acoustic environment planning and environmental policy formulation.关键词
