Safety in work zones continues to be a major focus for both departments of transportation (DOTs) and roadway construction contractors. Recent research has identified practices that help to reduce speed and speed variation in work zones and alert workers of work zone intrusions. This presentation will describe recent and current research aimed at providing DOTs and contractors with guidance on practices determined to eliminate safety risk during traffic control operations as well as during the construction operations after the work zone is set up.
