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

|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.
