Abstract

Regional cooperation, global trade, and the growing demand for transportation necessitate the development of efficient transport networks. This study aims to establish a comprehensive knowledge base on the evolution of transport networks, assess major axes and corridors, identify emerging trends, and highlight existing research gaps. To achieve this, a thematic taxonomy was developed based on objectives, topics, scope, keywords, methodologies, and similarities. Using the Web of Science (WoS) database, 937 publications related to transport networks and corridors were initially retrieved. Of these, 198 articles were selected and analyzed through three stages: assessing the accessibility of the papers, checking for overlap, and conducting content analysis. Recent studies on transport network and corridor assessments indicate that since 2021, the keywords 'Bayesian network', 'transport corridor', 'resilience assessment', and 'quality' have gained increasing prominence. The articles assessing transport networks and corridors can be categorized into five clusters according to the thematic taxonomy: (1) investment and benefit analysis, (2) performance assessment, (3) environmental, social, and economic impact analysis, (4) resilience and risk analysis, and (5) comparative assessment of alternatives. The methods most commonly employed in these assessments include multi-criteria analysis, data envelopment analysis, and time–cost–distance methods. While studies evaluating transportation alternatives have increasingly focused on efficiency, they have largely overlooked the issue of optimal spatial location. A comprehensive assessment that simultaneously addresses both efficiency and optimal spatial location could provide significant advantages.
