Abstract

Solid safety barriers are commonly constructed along highways. These barriers improve highway safety by preventing collisions and providing separation from slopes or adjacent hazards such as deep water. For elevated and at-grade roadways, shorter barriers have also been shown to noticeably reduce traffic noise. In prior research, modeling methods were developed and evaluated for their ability to accurately calculate the performance of short barriers in reducing traffic noise at the wayside. The modeling results were compared to available field data and to the results of FHWA's Traffic Noise Model version 2.5 (TNM). This paper extends the prior research to compare the results to the newest FHWA TNM version, 3.1.

在FHWA更新的交通噪音模型(TNM) 3.1版中对短安全屏障的噪音建模

坚固的安全屏障通常在高速公路沿线建造。这些屏障通过防止碰撞和与斜坡或邻近的危险(如深水)隔开，提高了公路的安全性。对于高架和地面道路，较短的障碍物也被证明可以显著减少交通噪音。在之前的研究中，建模方法被开发和评估，以准确计算在路旁的短障碍物的性能，以减少交通噪声。建模结果与现有的现场数据以及FHWA的交通噪声模型2.5版(TNM)的结果进行了比较。本文扩展了前人的研究，将结果与最新的FHWA TNM版本3.1进行了比较。

期刊介绍： Noise and Health is the only International Journal devoted to research on all aspects of noise and its effects on human health. An inter-disciplinary journal for all professions concerned with auditory and non-auditory effects of occupational, environmental, and leisure noise. It aims to provide a forum for presentation of novel research material on a broad range of topics associated with noise pollution, its control and its detrimental effects on hearing and health. It will cover issues from basic experimental science through clinical evaluation and management, technical aspects of noise reduction systems and solutions to environmental issues relating to social and public health policy.
