Synthesis of Information Related to Highway Practices. Topic 55-19. Practices for Managing Selected Ancillary Transportation Assets

State departments of transportation (DOTs) are increasingly expanding transportation asset management activities beyond pavements and bridges, by including selected ancillary transportation assets. Management of ancillary transportation assets are described in state DOTs recently completed and certified transportation asset management plans (TAMPs) and informal TAMPs. Recent research, including NCHRP 08-36, Task 114, Transportation Asset Management for Ancillary Structures, has documented approaches to managing these selected assets, and several state DOTs have developed programs of differing levels of maturity. Additionally, NCHRP 20-05/Topic 54-06, Ancillary Asset Data Stewardship and Data Models, focused on which ancillary asset data is collected, and how it is collected, stored, managed, and used. These selected ancillary transportation assets are identified from state DOT asset hierarchy based on research and features inventories' evaluations. Selected ancillary transportation assets include (but are not limited to): (1) Sidewalks and curbs; (2) Culverts; (3) Drainage systems and environmental mitigation features; (4) Overhead sign and signal structures; (5) Intelligent transportation system equipment; (6) High mast light poles; and (7) Network backbone. The objective of this synthesis is to document practices used by state DOTs for managing selected ancillary transportation assets. Information to be gathered includes (but is not limited to): (1) Selected ancillary transportation assets included in state DOT transportation asset management activities; (2) Documented approach for ancillary transportation assets in state DOT TAMPs, as it relates to federally required elements; (3) Ancillary transportation assets included in state DOT TAMPs, certified or informal; (4) Performance measures and targets for these selected ancillary transportation assets; (5) Selected asset management financial planning, including budgets, forecasting capabilities, and specific work/treatment types; (6) Selected asset data used for programming decisions, including identification of the decision-maker; (7) Identifying how these efforts are tied to broader asset management, maintenance management, and capital programming; (8) Life-cycle planning methods and strategies; and (9) Risk and resilience strategies.
