Over the last decades, Transit-Oriented Developments (TODs) have stimulated various debates in several contexts including environmental and transportation planning. Scholars have explored the TODs’ broad spatial and socioeconomic characteristics; however, very few studies (if at all) have conducted their attributes including mixedland use in regards to noise, particularly when they require such examination. This paper aims to explain and explore TODs’ implications associated with noise by comparing them with non-TODs in the Dallas-Fort Worth metroplex area. The data include sound pressure levels (SPLs) and various built environment features through TOD stations and surrounding areas compared with non-TOD stations by performing the grid sampling method. Using a unique two-level hierarchical linear model (HLM), the study examines the impacts of TODs on noise both at micro and macro levels. The findings show that with their features TODs generate higher sound levels with almost 9.0 dB(A) difference. The study provides insights into the relationship between noise, land use, and transportation by discussing their practice and policy implications.

在过去的几十年中，面向交通的发展（TOD）在包括环境和交通规划在内的多个环境中引发了各种辩论。学者们探索了TOD的广泛空间和社会经济特征。然而，很少有研究（如果有的话）进行了包括杂种土地使用在内的关于噪声的属性研究，特别是在需要进行此类检查时。本文旨在通过与达拉斯-沃思堡大都会区的非TOD进行比较，来解释和探索TOD与噪声相关的含义。数据包括声压级（SPL）和通过TOD站及周边区域与非TOD站相比的各种建筑环境特征（通过执行网格采样方法）。使用独特的两级分层线性模型（HLM），这项研究从微观和宏观两个层面考察了TOD对噪声的影响。研究结果表明，TOD凭借其功能可以产生更高的声级，几乎相差9.0 dB（A）。这项研究通过讨论噪音，土地使用和运输之间的关系和政策含义，提供了洞见。
