Guidelines on Managing Speeds in Work Zones summarizes available guidance on setting speed limits and managing speeds in work zones. Many factors impact the decision to reduce the regulatory speed limit in a work zone, implement speed limit management strategies and utilize speed reduction strategies. This guide is intended to aid agencies and highway contractors in understanding these factors and the interactions among them. The document addresses how slower speeds can improve safety, how drivers are told to slow down, when slower speeds are important, changing speeds to match conditions, voluntary speed reductions, law enforcement, other tools, a decision tool for managing speeds, and an example approach to managing speeds in work zones.
