Abstract: Signaling delineator assemblies and methods are disclosed. One example delineator assembly includes a delineator that has a base portion and a top portion, with the base portion being configured to stand on a level surface, and with the top portion having at least one aperture. An adapter bracket extends through the aperture and comprises at least one pole connection portion and a first portion and a second portion. The first portion contacts a first side of the at least one aperture and the second portion contacts a second side of the at least one aperture. A signaling pole is connected to the at least one pole connection portion and extends away from the adapter bracket. The delineator assembly adapts conventional delineators to have increased height and visibility so that they are more visible to tall vehicles such as tractors and aircraft.
