Evaluation of Ohio Work Zone Speed Zones ProcessAuthor/Presenter: Finley, Melisa D.; Jenkins, Jacqueline; McAvoy, Deborah
This report describes the methodology and results of analyses performed to determine the effectiveness of Ohio Department of Transportation processes for establishing work zone speed zones. Researchers observed motorists’ speed choice upstream of and adjacent to various work zone conditions used to justify reduced speed limits in work zones. Researchers also observed speed choice upstream and within variable work zone speed zones.
Based on previous research and the results of the studies documented herein, researchers made recommendations regarding appropriate speed limit reductions for shoulder activity, lane shifts, lane closures, and median crossovers. Researchers also recommended the expanded use of variable work zone speed zones.
