Abstract

This study offers a comprehensive assessment of the dynamic changes in transportation-related noise exposure among six racial-ethnic groups across 31 metropolitan divisions in the United States. Our findings indicate that the variation in noise exposure within cities significantly surpasses variation between cities. Moreover, population-weighted transportation noise exposures have increased from 2016 to 2020, particularly for minority racial-ethnic groups. Asians, Native Americans, and Pacific Islanders experience the most pronounced disparities in noise exposures. The disparity becomes even more acute in high noise conditions (exceeding 65 dB), with all minor racial-ethnic groups facing higher-than-average noise exposures. Our study highlights the increasing significance of transportation noise exposure in US cities, with a disproportionately adverse impact on minority racial-ethnic groups. These findings underscore the critical need to address the unequal exposure to transportation noise experienced by vulnerable populations.

随着时间的推移，美国各大城市交通噪声暴露的差距越来越大

本研究全面评估了美国 31 个大都市分区的六个种族-民族群体在与交通相关的噪声暴露方面的动态变化。我们的研究结果表明，城市内部噪声暴露的变化大大超过了城市之间的变化。此外，从 2016 年到 2020 年，人口加权的交通噪声暴露量有所增加，尤其是少数种族族裔群体。亚洲人、美国原住民和太平洋岛民在噪声暴露方面的差异最为明显。在高噪声条件下（超过 65 分贝），这种差距变得更加严重，所有少数种族-民族群体都面临着高于平均水平的噪声暴露。我们的研究凸显了美国城市交通噪声暴露日益严重的问题，对少数种族群体的不利影响尤为突出。这些研究结果突出表明，亟需解决弱势群体在交通噪声暴露方面的不平等问题。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
