Delineators: Delineators are tall pylons mounted on the road surface, or along the edge of a road, and are used to channelize traffic. These are a form of raised pavement marker which are tall enough to impact not only a vehicle’s tires but the vehicle body itself. They usually contain one or more reflective strips. They can be round and open in the centre or curved (45-degree sections) of plastic with a reflective strip. They are also used in low reflective markers in a “T” shape. They can also be used to indicate lane closures as in cases where the number of lanes is reduced.
