Specifications include, but are not limited to: The objectives of this research are to: -Enable NCHRP to provide program sponsors/state DOTs with useful and actionable information about the impacts and value of NCHRP research products. -Develop guidance (including definitions, assumptions, assessment tools, and methods) that will enable NCHRP to consistently measure the value and impacts of its research products over time. The guidance may also be applicable to state DOTs. -Demonstrate use of the guidance by applying it to a variety of NCHRP research products and research portfolios to estimate, measure, or assess the value accrued through application of the results. -Recommend changes to the NCHRP program and processes that will enable future assessment of value. Recommendations must consider the cost of implementation, including training on how to implement the guidance, and likelihood of success by NCHRP and state DOTs.
