Return on Investment in Transportation Asset Management Systems and Practices TRB's National Cooperative Highway Research Program (NCHRP) Research Report 866: Return on Investment in Transportation Asset Management Systems and Practices explores how transportation agencies manage their transportation assets, and provides guidance for evaluating the return on investment for adopting or expanding transportation asset management systems in an agency. As the term is most generally used, transportation asset management (TAM) entails the activities a transportation agency undertakes to develop and maintain the system of facilities and equipment--physical assets such as pavements, bridges, signs, signals, and the like--for which it is responsible. Based on the research team's work and the experiences of these agencies and others, the researchers describe a methodology that an agency may use to assess their own experience and to plan their investments in TAM system development or acquisition. A spreadsheet accompanies the research report helps agencies evaluate the return-on-investment of TAM systems.The tool allows users to summarize data from various simulation tools. The calculator also includes factors and procedures from the Highway Economic Requirements System State Version (HERS-ST) to estimate user benefits for pavement projects. It does not estimate user benefits for bridge projects. -- cf. http://www.trb.org/main/blurbs/177179.aspx.
TRB's Transit Cooperative Research Program (TCRP) Report 157: State of Good Repair: Prioritizing the Rehabilitation and Replacement of Existing Capital Assets and Evaluating the Implications for Transit presents a framework that builds upon a set of fundamental concepts and provides a basic set of steps for transit agencies to follow when evaluating and prioritizing capital asset rehabilitation and replacement investments. In addition to the printed report, an analytical approach and set of spreadsheet tools were developed to support the framework. These tools address how to evaluate rehabilitation and replacement actions for specific types of transit assets, and how to prioritize candidate rehabilitation and replacement actions."--Publisher's description.
