A review of multilayer networks-based interregional transportation networks analysis

The interregional transportation networks (ITNs) have a significant impact on regional population movement, trade flow and economic development. Compared to single-layer networks, multilayer networks theory can help ITNs to capture more detailed information applied to transportation plan, design and management. Despite the growing interest in studying ITNs using multilayer network analysis, attempts to document and better understand this area have largely remained elusive. To fill the gap, this article provides a comprehensive bibliometric assessment of multilayer networks-based ITNs analysis. Three research aspects, including the construction, characteristics, and functions of ITNs analysis based on multilayer networks theory has been systematically reviewed. Through analysis, research on multilayer networks-based ITNs are expanding from aviation networks to other ITNs and evolving from static to dynamic networks. In the future, advancements are expected in the establishment of interlayer relationships, the development of composite ITNs, effective management of dynamic network risk propagation, and enhancement of system robustness.
