Transportation Asset Management Guidance and Framework for Ancillary Highway Assets

Ancillary assets represent a significant portion of state department of transportation (DOT) asset inventory. Current research on the state of practice summarizes ancillary asset management processes; however, state DOTs still face challenges in developing procedures and guidelines to establish comprehensive practices or improve existing programs. The Federal Highway Administration (FHWA) 2019 Handbook for Including Ancillary Assets in Transportation Asset Management Programs shows progress in this area, though knowledge gaps in data management and systems, life-cycle planning (LCP), and preservation and maintenance programs still exist for managing ancillary assets. Research is needed to identify and assess state DOT practices for performing ancillary asset assessments and managing these asset classes. The objective of this project is to develop a guide and framework for state DOTs to manage multiple ancillary asset classes, including hydraulics, signals, barriers, culverts, intelligent transportation systems, and other relevant assets.
