Kentucky Transportation Center Research Report

The Kentucky Transportation Cabinet’s Division of Maintenance is responsible for identifying and prioritizing locations in need of guardrail. A procedure used by the Kentucky Transportation Cabinet was originally developed by the Kentucky Transportation Center in 1989 and updated in 2002. Based on frequent usage by the Kentucky Transportation Cabinet of the guardrail location rating system database, the need was identified to update the existing database and incorporate improved reporting capabilities. The objectives of the research study, as documented herein, were to update and improve the processes for identification of roadway locations that should be considered for installation of guardrail. Primary …


Evaluation Of The Use Of Snowplowable Raised Pavement Markers, Kenneth R. Agent, Eric R. Green Apr 2009

Evaluation Of The Use Of Snowplowable Raised Pavement Markers, Kenneth R. Agent, Eric R. Green

Kentucky Transportation Center Research Report

The objective of this study was to evaluate the effectiveness and durability of snowplowable raised pavement markers (RPM) installed on the RPM system in Kentucky. The durability evaluation dealt with the marker housing.

The data show that continued use of the currently approved snowplowable RPM can be justified if the castings are properly installed on new pavements with a commitment that the pavement will be maintained. An evaluation of centerline rumble strips installations showed that they should be considered on rural, two-lane roads with 12-foot lane widths (having new pavements) and paved shoulders.


Evaluation Of The Work Zone Safety And Mobility Rule, Kenneth R. Agent, Jerry G. Pigman Mar 2009

Evaluation Of The Work Zone Safety And Mobility Rule, Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

The Work Zone Safety and Mobility Rule (Rule) was published in the Federal Register in September 2004 indicating that all state and local governments receiving Federal-aid funding were required to comply with provisions of the Rule no later than October 2007. Kentucky received an extension to October 2008. The objectives of this study were to review the requirements of the Work Zone Safety and Mobility Rule and provide recommendations for implementation of the Rule to ensure a consistent approach for designing and managing the impacts of work zones. This report documents results from: a) a review of literature and Kentucky’s …
