A Meta-Analysis of Dynamic Speed Feedback Signs

This project will conduct a comprehensive review of the existing literature on dynamic speed feedback signs from 2000 to the present, produce an annotated bibliography of all studies found, and conduct a quantitative systematic review of these studies, including a meta-analysis if sufficient qualifying studies are available. The final report will provide a synthesis of all the existing studies and a quantitative systematic review (including a meta-analysis) of qualifying studies to evaluate the effectiveness of speed feedback signs. The final product will provide an important resource for both highway safety practitioners interested in reducing speeding and speeding-related crashes and researchers interested in doing further research on this important and widely accepted traffic safety countermeasure.

• Supplemental Notes:
  • This study is being conducted under the National Cooperative Research and Evaluation Program (NCREP), which is administered by the National Highway Traffic Safety Administration (NHTSA) and jointly managed by NHTSA and the Governors Highway Safety Association.
