What are Delineators used for in traffic management?

Delineators are vertical objects used in traffic management primarily to guide and direct vehicles along roadways, especially in areas where alignment or visibility may be compromised. They serve as visual markers that indicate the path of travel, signal changes in the roadway, or delineate lanes. Their distinctive shapes and reflective surfaces enhance visibility, particularly at night or in adverse weather conditions.

They do not function to limit vehicle speed directly, which is typically the role of speed limits, speed bumps, or signage indicating lower speed zones. While they can enhance pedestrian pathways indirectly by clarifying vehicle routes, their main purpose is not to create pathways for pedestrians. Additionally, delineators are not involved in signaling changes for traffic lights; that is the role of traffic signals and associated signage. Thus, their primary function rests in their ability to provide guidance and direction to ensure safer and more efficient traffic flow.
