TAM - Synthesis: Best Practices for Managing Ancillary Transportation Assets
Funding
Research Period
Description
In July 2012 MAP-21 established requirements that each state developed a Transportation Asset Management Plan (TAMP) that, at a minimum to include pavement and bridge assets on the National Highway System (NHS) (23 USC 119). This requirement was further detailed, in October 2016, through the issuance of 23 CFR 515, that encourages but dos not require State DOTs to include all NHS infrastructure assets in their TAMPs, (23 CFR 515.9(c)). This can include major asset classes such as tunnels or “ancillary” asset classes, such as:
• Guardrail
• Sidewalks
• Small Culverts
• Sign Structures
• Retaining Walls
• ITS Equipment
• Traffic Signals
While many states are including these assets in their TAMPs, many others manage these assets outside their federal TAMPs in an effort to right-size the associated workload and costs.
Literature Search Summary
• FHWA’s Handbook for Including Ancillary Assets in Transportation Asset Management Programs (2019)
• FHWA’s Case Study 7 – Managing Assets Beyond Pavements and Bridges (2020)
• HIF-20-067 Case Study 7-Managing Assets Beyond Pavements and Bridges (TAMP Practices on Other Assets) (dot.gov)
Objectives
Recent research has documented approaches to performing this work and several states have developed programs of differing levels of maturity. A Synthesis project at this time will enable agencies to understand the current state of the practice and identify leading practices that can be adopted to advance their own programs.
