Bibliometric analysis and visualization of sustainable infrastructure

In comparison with other construction sectors, infrastructure projects are recognized for their relatively longer operation periods, important societal, economic benefits, and extensive consumption of natural resources. The rapid global economic development in the infrastructure industry and rising levels of environmental concerns lead to an increased need for sustainable infrastructure. Despite the fast-growing body of knowledge about sustainable infrastructure and its important role in accomplishing the Sustainable Development Goals which were set forth by the United Nations in 2015, there is a lack of quantitative and comprehensive review studies of sustainable infrastructure. Most of the conducted studies tend to address sustainability issues in infrastructure projects from singular aspects such as society-based design and Public Private Partnerships, among others. Hence, the current research attempts to address this gap by analyzing 1393 peer-reviewed journal papers between 2012 and 2023 using bibliometric analysis through co-authorship, co-occurrence, cluster, theme, trend topics, and citation analyses. The results demonstrate the main scientific contributors, prominent journals, research patterns, and directions for future research about sustainable infrastructure in the field of civil engineering and building construction. Such findings can be thus utilized by interested academic researchers and policymakers.
