• Abstract:
  As part of the ongoing evolution towards integrated highway asset management, the Indiana Department of Transportation (INDOT), ; through SPR studies in 2004 and 2010, sponsored research that developed an overall framework for asset management. This was ; intended to foster decision support for alternative investments across the program areas on the basis of a broad range of performance ; measures and against the background of the various alternative actions or spending amounts that could be applied to the several ; different asset types in the different program areas. The 2010 study also developed theoretical constructs for scaling and amalgamating ; the different performance measures, and for analyzing the different kinds of trade‐offs. The research products from the present study ; include this technical report which shows how theoretical underpinnings of the methodology developed for INDOT in 2010 have been ; updated, upgraded, and refined. The report also includes a case study that shows how the trade‐off analysis framework has been ; calibrated using available data. Supplemental to the report is Trade‐IN Version 1.0, a set of flexible and easy‐to‐use spreadsheets that ; implement the tradeoff framework. With this framework and using data at the current time or in the future, INDOT’s asset managers are ; placed in a better position to quantify and comprehend the relationships between budget levels and system‐wide performance, the ; relationships between different pairs of conflicting or non‐conflicting performance measures under a given budget limit, and the ; consequences, in terms of system‐wide performance, of funding shifts across the management systems or program areas.
