Connecting Transportation Asset Management (TAM) and Transportation System and Management Operations (TSMO)

  Project Data
Funds: $500,000
Staff Responsibility: Lawrence D. Goldstein
Fiscal Year: 2021

This project has been tentatively selected and a project statement (request for proposals) is expected in August 2020. The project statement will be available on this site. The problem statement below will be the starting point for a panel of experts to develop the project statement.

Since the early adoptions of transportation asset management (TAM) practices, and performance rule-making association with the Fixing America’s Surface Transportation (FAST) Act, state agencies have been encouraged to add assets beyond pavements and bridges in their risk-based transportation asset management plans (TAMPs). With rapidly growing advancements and uses of technology in transportation system and management operations (TSMO), new assets are becoming widespread critical components of the network such as communications and security technology, sensors, cameras, and other intelligent transportation system (ITS) infrastructure technologies.

TAMPs cross multiple functions (e.g., planning, engineering, maintenance, operation, finance and procurement) entailing the management and inclusion of all the components required to achieve the TAMP goal, which is maintaining and improving physical assets with a focus on engineering and economic analysis based upon quality information. Typically, transportation agencies focus on the benefits of deploying new technologies when installed and implemented in the exploration stage. However, moving forward to an exploitation phase, agencies need to start considering the long-term management of these technologies to maintain their good operational state.

In addition to managing the condition of TSMO assets, TAM decisions to other assets will have an impact on the operations of the network, such as traffic flows, that depend on traffic management and operations. The timing of the traffic management installation could span from the 20 minutes necessary to “make safe” a pothole in a live travel lane, to the multi-year management of lanes through a construction zone. Delivery of the TAMP is therefore dependent on safe, planned, and dependable access to the transportation infrastructure.  Several agencies have realized the need to link TAM and TSMO from the early stages of developing their TAMP; however, establishing the connection was challenging and hard to achieve in most cases. Currently, Ohio DOT is in the process of connecting TSMO and TAM as reported in their TAMP. Additionally, Caltrans has been including their transportation management system (TMS) technology assets into the TAMP.  Based on these changing conditions, the objective of this research is to investigate the needs and benefits from incorporating TSMO assets in TAMPs. The study will develop a guide for state DOTs to facilitate the inclusion of TSMO in TAMP without disrupting the established and on-going planning process.
