Transportation sector has become a major contributor to the escalation of carbon emissions and subsequent climate change. In this study, a bibliometric analysis was conducted using CiteSpace on published papers (1991-2022). Then a theoretical framework was proposed through traditional content analysis from three aspects: measurement, mechanism analysis, and low-carbon pathways analysis. The clustering results show that the research topics have involved mainly factor analysis, evaluation, system analysis, control measurement and pollutants. A further summary of the content of the relevant literature shows that there are five main accounting methods for measuring transportation carbon emissions (TCEs), which can be applied to different scenarios. Studies involving the spatio-temporal distribution of TCEs is limited and mainly focus on macroperspectives. The mechanism of TCEs involves three main aspects: system assessment, efficiency measurement, and driver analysis, which serve to identify the internal patterns of TCEs. Finally, the outlook regarding TCEs is presented.
交通运输部门已经成为碳排放加剧和随后气候变化的主要贡献者。在这项研究中，我们使用 CiteSpace 对发表的论文（1991-2022 年）进行了文献计量分析。然后，我们通过传统的内容分析从三个方面提出了一个理论框架：测量、机制分析和低碳路径分析。聚类结果表明，研究主题主要涉及因素分析、评价、系统分析、控制测量和污染物。对相关文献内容的进一步总结表明，有五种主要的交通碳排放（TCEs）计量方法，可适用于不同场景。涉及 TCEs 时空分布的研究有限，主要集中在宏观方面。TCEs 的作用机制涉及系统评估、效率测量和驱动因素分析三个主要方面，有助于识别 TCEs 的内部模式。最后，对 TCEs 的展望进行了阐述。
