Traffic cones are part of the common traffic equipment that is in the shape of a sugar cone or the same cone and are usually made of plastic, and the purpose of using them is changing the temporary route of the roads to direct car traffic safely.

History of the traffic cone

The traffic cone was first built in 1914 by Charles P. Rudabaker. Although at that time there was no copyright registered in his name this matter has a special document and evidence. The first type of traffic cone was made of cement and/or wood, but it caused a lot of damage during car accidents.

Later in the 1940s, Charles D. Scanlon, an employee of the Los Angeles Department of Highways who painted traffic signs on the street floor, invented the first hollow cone-shaped traffic sign. Scanlon got the idea from the idea of ​​keeping cars away from painted traffic signs. The first traffic cone made by Scanlon was made using used tires, but Scanlon quickly gave up on making them because he could not find a permanent source of used tires.

In 1947, a multi-state tire company began making traffic cones using rubber and heat molds. David Morgan, an engineer from the UK, also claims to have built the first plastic traffic cone while working at Royal Chemicals.

In 1958, the use of commercial traffic cones was extended and paraffin-burning warning lights replaced the traffic cones and were used on the M6 highway. Oakland, California’s Gas and Electric Company also began using traffic cones to protect workers unloading and loading trucks. In 1961, the Federal Highway Administration adopted a highway safety standard that required rubber cones to be yellow or orange-yellow with a red section at the tip. In 1971, the United States Uniform Traffic Control Standards approved that traffic cones should be 18 inches or larger, and in areas where vehicle speeds are higher, these cones should have light-colored and shiny stripes to illuminate vehicles at night. And in 1978, the organization adopted a minimum cone height of 28 inches for freeways.

When was the traffic cone used as one of the traffic equipment for the first time?

Reports indicate that Rudebaker’s cement cones were first seen in New York City. Also, the traffic cone was used as one of the traffic equipment in England for opening the M6 highway in 1958.

What is the type of traffic cone?

In the past, these cones were made of wood and cement, but today’s traffic cones are made of recycled thermoplastic, rubber, or PVC, and if the cars collide with them unintentionally, there will be no more damage to the cars, and some types of rubber are folded under the car and return to their original state after coming out.

Although there are no exact statistics for the number of traffic cones in the world, it is estimated that there are 1.3 million traffic cones in the UK and 140 million worldwide.
