The objective of this research is to develop a guidebook that state transportation agencies and others can use for calculation and communication of the value of transportation assets, and for selecting valuation methods to be used in transportation asset management. This guidebook, applicable to transit as well as highway modes, should (1) present a standardized terminology for discussing asset value, (2) describe currently accepted valuation methods, (3) describe the merits and shortcomings of these methods to produce measures of asset value useful for communicating among stakeholders and making resource allocation decisions, and (4) present advice on determining which valuation methods will be most useful in communication and decision-making for a particular agency.
The guidebook shall include at least the following components:
• Terminology and definitions of asset value (a) determined by generally accepted accounting principles, considering initial acquisition or construction costs and depreciation, (b) based on engineering estimates to replace the asset (considering age, condition, obsolescence, and the like), (c) based on estimates of revenues that could be produced from the assets if they were operated as a business venture, (d) based on socio-economic returns to a region’s economy and wellbeing, or (e) other relevant definitions;
• Current best practices for computation and presentation of each of the definitions of value listed above, presented in a manner that can be used by transportation agencies;
• Analysis of the advantages and shortcomings of the value methods as factors to be considered in system-level resource allocation decisions, for example, investment planning, maintenance budgeting, lifecycle management, and presentations for public discussion;
• Identification and description of needs for data and information for value computations;
• A capability-maturity model that an agency can use to characterize its valuation practices and needs and strategies for improvement;
• Advice on incorporating valuation estimates into the agency’s asset management practices.
NCHRP anticipates that the guidebook may be published by AASHTO. It should be compatible with print and web-based versions of AASHTO’s Transportation Asset Management Guide.
