Recent advances in network theory hold promise for improving how infrastructure managers make decisions about their portfolio of assets. A framework that incorporates contemporary perspectives of networks is presented, which permits modeling the topology of an infrastructure network. The framework is capable of characterizing the components of the overall system and subnetworks and the direct and indirect interactions among these components. This framework is applied to a transportation system, which allows the authors to investigate the importance of the various components as elements of a complex network and use this data to support transportation asset management. The study shows that the links determine how the infrastructure network grows and that problems like congestion can be addressed by analyzing other factors related to topology, such as speed, unit size, and lane width. The proposed methodology appears promising as an asset management tool.

Key Words: infrastructure • network theory • network topology • transportation asset management • transportation systems
