Abstract Over the past three decades, Transit-Oriented Development (TOD), with transit as its central tenet, has emerged as a pivotal urban policy driving sustainable and intelligent urban growth, drawing significant attention from researchers and practitioners worldwide. TOD involves creating high-density, mixed-use, pedestrian-friendly urban areas around transit stations to enhance transit accessibility, promote social cohesion, and improve housing conditions. However, the global implementation of TOD has encountered challenges across various domains including transportation, housing, and employment, thereby exacerbating inequities within the built environment. This study adopts a TOD perspective to comprehensively review the equity impacts of urban rail transit (URT) station areas on the built environment, with a particular focus on social, travel, perception, health, and spatial dimensions, and their impacts on promoting or hindering equitable outcomes among diverse societal groups. Utilizing a scoping review methodology, the study encapsulates the progress and themes in the field, employing a systematic approach to meticulously analyze the outcomes of each research theme. The findings reveal that URT station areas have positive impacts on economic growth and property values. However, they can also contribute to gentrification, exacerbating disparities between different societal groups in station and non-station areas, along with an unequal distribution of resources and opportunities. Additionally, while these station areas encourage pedestrian activity and public transportation usage, they also carry the potential for environmental pollution, raising concerns about spatial accessibility and facility convenience, thereby impacting environmental equity. This study employs comprehensive and critical theoretical analyses, utilizing intricate methods and detailed indicators, to elucidate disparities in equity outcomes of URT station areas across different societal groups. The crucial challenge in future research lies in integrating the concept of equity into TOD planning strategies. This study aims to provide standardized and harmonized criteria for guiding equitable TOD planning policies, thereby enhancing the scientific basis and effectiveness of planning strategies. Ultimately, it seeks to offer theoretical insights towards the creation of a more equitable and inclusive urban built environment in the future.
