Abstract: A basally adhered, self-recovering traffic lane delineator has a cylindrical post made of flexible material, having the air outlet and inlet on the center of its upper surface, and a supplementary support panel placed and adhered underneath the post. The support panel supports a lower part of the post and is adhered on the ground. Owing to its small package volume, the delineator is easy to move and safeguard.

Abstract: A traffic collar cone has a delineator having a reflection sheet attached on its upper part. A plug is placed under the sheet having an air inlet and outlet extending upwardly and downwardly therethrough. A conical body member is provided, having in its upper end wall an insertion hole in which the plug is mounted. A support panel is provided at the bottom of the body and cone collars are attached on the outer surface of the body member, with vertical spacing between them. The traffic collar cone is made of flexible material and designed to recover its original shape after being impacted, so that injury to collar cone is eliminated or minimized. The support panel can be adhered onto a roadway.
