Examination of the Current Practice of Lighting in Virginia: Nighttime Work Zones and Improving Safety through the Development of Nighttime Lighting Specifications

Project No: 105582

Target Completion Date: September 22, 2017 Safety, Operations, and Traffic Engineering

About the project:

style="MARGIN: 0in 0in 0pt">As traffic increases on U.S. roads, more construction activities are occuring at night when volumes are lower but travel speeds tend to be greater. Approximately 40 percent of all work-zone crashes occurred at night in 2011


The purpose of this project is to:

·        Evaluate current nighttime work-zone lighting practices used on limited-access highways and primary route work zones, and

·        Develop effective nighttime work-zone lighting requirements in Virginia.


The results of this research effort will be implemented through the development of new specifications and a modification of the 2011 Virginia Work Area Protection Manual, thus changing and improving existing practices for lighting nighttime work zones in Virginia.
