Synthesis of Information Related to Highway Practices. Topic 55-19. Documenting the State of Practice in Managing Ancillary Transportation Assets

State departments of transportation (DOTs) are increasingly expanding transportation asset management programs beyond pavements and bridges, by including selected ancillary transportation assets. Example ancillary transportation assets include (but are not limited to): hydraulic structures (e.g. culverts, drainage systems); overhead sign and signal structures and signal systems; bicycle and pedestrian infrastructure (e.g. sidewalks and curb ramps); intelligent transportation systems and communications infrastructure; high mast and highway light poles; traffic barriers (e.g. guardrail); earth retaining structures; sign panels and supports; and building facilities. Management of ancillary transportation assets may be described in state DOTs recently completed and certified transportation asset management plans (TAMPs) and/or in other formal and informal documentation. While research has explored data collection, asset management, and data storage and use for the management of ancillary assets, it is unknown to what extent state agencies have implemented and used these resources for asset management. The objective of this synthesis is to document practices used by state DOTs for managing selected ancillary transportation assets, including levels of maturity and variability of practice across state DOTs.
