About the research

This research will support the Iowa Department of Transportation through ad hoc implementation of the methods developed in a previous draft report entitled, “A Transportation Agency Data Collection Practice for Use with In-Service Performance Evaluations (ISPEs).” This will include analysis of data related to traffic barrier elements and roadside hardware such as crash cushions, steel beam, cable, concrete barriers, breakaway signs, breakaway light poles, etc. Research will include both a review of the data and optional implementation.
