TAM Gap Analysis Tool
The 2011 AASHTO guide introduced an Excel-based Gap Analysis Tool to illustrate the application of a gap analysis to identify and prioritize needed enhancements. While the tool served as a good starting point for several agencies, improvements to the functionality, flexibility, and user experience were needed for it to be widely used. These changes and enhancements were addressed under National Cooperative Highway Research Program (NCHRP) Project 08-90, which developed a new TAM Gap Analysis Tool. The results of the research study are documented in the Project final report, while the User’s Guide supports the operation and use of the new tool.
Note: The Excel-based Gap Analysis Tool was originally developed in Excel 2007 for Windows and tested in Excel 2010 for Windows. Any other edition of Excel may be unsupported, including Excel 2013 and all versions of Excel for Mac OS X.
