History, Types, and Uses of Traffic Delineator Posts

Delineator posts have been developed over time into light weight, versatile and highly visible traffic safety products.  Many different variations exist and there are equally as many applications for these durable reflective devices. 

Initial traffic safety products were often made of wood and metal, making them cumbersome and expensive, with limited applications. These were one-use-only products.  More lightweight and advanced materials were still experiencing design flaws that made them bulky and obtrusive.  As vehicular technology advanced, leading to higher speeds and traffic volumes, a need emerged for more accurate routing and channelization. Today’s posts are made of durable polymers and plastics, in which some designs can withstand up to and beyond 50 impacts.  Retro-reflective adhesives are applied to make these posts highly visible in both day- and nighttime driving conditions. Additionally, the use of these materials makes modern delineators far more cost effective- based on life cycle costs, than their older counterparts. 

Delineator posts come with a variety of base, color, sheeting and height options.  Impact Recovery Systems offers their delineator posts with a variety of base options: fixed, quick release, magnetic, as well as other options. Colors play a large role in communicating with drivers and pedestrians.  For example, shades such as orange warn of construction areas, whereas white or yellow are used for delineation and roadway guidance. A variety of height options can also be employed whether industry specific or a custom height is needed. Common uses for posts include channelization of traffic in work zones, as warning indicators to restrict turns or to identify changes in road alignment.
Now that road-construction has become a highly sophisticated science, the devices used in keeping roadway users safe has adapted appropriately.  They are versatile, durable, and best of all, cost-effective to install and maintain.
