Traffic cone
Traffic cones, also called traffic pylons, road cones, highway cones, safety cones, witch's hat, or construction cones, are usually cone-shaped markers that are placed on roads or footpaths to temporarily redirect traffic in a safe manner. They are often used to create separation or merge lanes during road construction projects or automobile accidents, although heavier, more permanent markers or signs are used if the diversion is to stay in place for a long period of time.
History
Traffic cones were invented by American Aaron Stanley, who got the idea for the traffic cone while working as a painter for the Street Painting Department of the City of Los Angeles. The patent for his invention was granted in 1943.
The first traffic cones used in the United Kingdom occurred In 1958, when the M6 motorway opened. These traffic cones were a substitute for red lantern paraffin burners being used during construction on the Preston Bypass. In 1961, David Morgan of Burford, Oxfordshire, UK believes that he constructed the first experimental plastic traffic cones, which replaced pyramid-shaped wooden ones previously used.
