What area is designated for lane changes and traffic closures?

The Transition Area is specifically designated for lane changes and traffic closures because it serves as the buffer zone where vehicles approach the work zone or incident site. This area is crucial for safely guiding drivers from the regular roadway into altered traffic patterns, such as reduced lanes or closures. It provides drivers with necessary warning and time to adjust their speed and position, helping to maintain safety for both the vehicles and personnel in the Activity Area, where the work is actually being done.

In contrast, the Advance Warning Area is meant to alert drivers about upcoming changes in the roadway ahead, but it does not play a direct role in facilitating lane changes. The Activity Area is where the actual work occurs, while the Incident Termination Area signifies the end of the work zone, allowing traffic to return to normal conditions. Thus, the Transition Area is crucial for managing the flow of traffic and ensuring that lane changes happen safely and systematically.
