A Bibliometrics-Based Visualization Analysis of Sustainable Transportation Infrastructure Research

Sustainable transportation infrastructure has profound social, environmental, and economic benefits for both individuals and societies. Recent years have witnessed a growing interest in this domain, and multiple studies have been conducted over the past decade. However, the existing body of knowledge concerning the present status of research within the domain of sustainable transportation infrastructure is limited. This study intends to identify the most significant articles categorically, track the recent trends of publications, examine the most common keywords, highlight their interconnections, and determine the most influential authors in the field of sustainable transportation infrastructure. The visualization analysis method based on bibliometrics, including performance analysis and scientific mapping, was performed. The performance analysis method involved studying the reviewed publications based on their types and topics and exploring the year-wise trend of publications. The scientific mapping method involved the keyword co-occurrence analysis and citation analysis. The outcomes of this study provide a comprehensive and structured understanding of the existing research landscape; highlight influential articles, authors, and trends; and offer insights that can guide future research efforts, policy-making, and industry development within the realm of sustainable transportation infrastructure.
