What type of devices can be used to redirect traffic in a work zone?

Traffic barrels, cones, and delineators are specifically designed to redirect traffic safely through work zones. These devices help create clear paths for vehicles, marking the boundaries of the work area and guiding drivers to navigate without entering hazardous zones. They are highly visible and can be used in various configurations, depending on the specific layout of the work zone, to effectively manage the flow of traffic.

In contrast, construction vehicles primarily serve operational roles and do not inherently manage traffic flow; street lights and signals are not typical tools for work zone traffic control but are used for general traffic management at intersections; safety vests and helmets are essential for worker safety but do not redirect traffic.
