Chapter 1: Understanding Traffic Cones & Barrels
A traffic cone is one of the most common objects in the built environment, and one of the least understood. It is not simply a piece of colored plastic. It is a carefully engineered communication device and a physical safety barrier, and its proper use is often mandated by law. To understand what a traffic cone or barrel actually is, you have to move past the visual cliche and look at its function: to change driver behavior in a predictable and safe way.
The primary function of a traffic cone is delineation. It defines the boundaries of a hazard, a work area, or a closed lane. A driver approaching a line of cones and barrels receives a clear, visual message: do not cross this line. This message is transmitted through high-visibility color, geometric form, and reflective materials. The bright orange or lime-green color is not an aesthetic choice. It is a color chosen for maximum contrast against the gray of asphalt and concrete. The cone's pyramidal shape with a wide base is designed for high wind stability and a low center of gravity, while the larger barrel, often a cylinder, uses its own weight and sometimes ballast to serve the same purpose.
How Cones and Barrels Work
A cone works in two distinct ways: visually and physically. The visual function is primary. The cone's color and reflectivity provide a high-contrast signal that is visible from a significant distance, allowing drivers to process
