Completed Research Readiness Level (RRL) Assessment
-
Research Readiness Level (RRL) Assessment identifies the immediate next steps for a research or technology development project by assigning an RRL number indicating how close to acceptance as standard practice the project is.
-
The RRL Assessment provides a systematic method for identifying how NDOT can best support the development of research at various stages in the process.
-
The RRL concept is based on the FHWA Technology Readiness Level Guide and was adapted to meet NDOT’s specific needs.
