• Abstract:
  MAP-21 and AASHTO’s framework for transportation asset management (TAM) offer opportunities to use more
  
  rigorous approaches to collect and apply evidence within a TAM context. This report documents the results of a study
  
  funded by the Georgia Department of Transportation, conducted by the Infrastructure Research Group (IRG) at Georgia
  
  Institute of Technology, to link TAM investments to outcomes. The study methodology includes a review of evidence based approaches from various fields including healthcare, education and organizational management, an “evidence
  
  exchange” among transportation practitioners, and several case studies demonstrating how evidence can be gathered
  
  and used in TAM. The study identifies attributes of an evidence-based approach that can enhance AASHTO’s existing
  
  framework for TAM program advancement and decision making. These attributes are used to develop (1) a hierarchy
  
  of evidence that can inform evidence-based decision making (EBDM) for TAM, (2) a documentation framework for
  
  TAM that can be applied at the project and program levels to support evidence-based decisions, and (3) a prototype
  
  evidence database that can be used to accumulate the knowledge needed for evidence-based decision making in a TAM
  
  context. This study also applies evidence-based decision-making processes to provide guidance on how to develop
  
  higher quality evidence for TAM decision making. The documentation framework is used to synthesize and gather data
  
  on evidence related to TAM decision making, and this information was used to populate the TAM evidence database.
  
  The primary outcome of this work is a prototype TAM evidence database and resource for knowledge sharing that can
  
  assist transportation agencies in meeting the performance-based planning requirements of MAP-21.
