What is the definition of a "transition area" in traffic control?

In traffic control, a "transition area" refers to a section of the roadway where the flow of traffic is altered or adjusted. This area is crucial for guiding vehicles from a normal route into a shifted or modified pathway, such as when roadwork is present or there are changes in vehicle movement due to detours or diversions. The purpose of the transition area is to ensure that drivers have adequate warning and space to adapt to the new conditions safely, ultimately helping to prevent accidents and maintain traffic flow.

This definition aligns precisely with the answer provided, emphasizing the importance of modifying traffic paths in a controlled manner. Understanding this concept is vital for anyone involved in road safety and traffic management, particularly in situations where road conditions change unpredictably.
