5 CHAPTER 1: Background Roadway construction and maintenance work zones are particularly hazardous driving and work environments for commuters and workers, respectively. Examples of conditions that create safety hazards in work zones are abundant, and include when the work is performed at night, the presence of high-speed traffic adjacent the work, limited or no positive protection of the workers, impaired drivers, and extreme weather conditions.

8 technologies that are designed to prevent an intrusion, detect that an intrusion has occurred, alert workers and motorists of an intrusion, and mitigate the impacts of an intrusion. Technologies are available that are designed for use during traffic control planning and design prior to the presence of the work zone.
