Often, traffic cones are referred to as traffic pylons, road funnels, highway funnels, safety funnels, construction cones or witches' hats on occasion. They are usually cone shaped markers that are strategically placed on roads or footpaths to temporarily transmit passages in a safe manner.
Usually they are meant to create separation or merge lanes when it is necessary for road construction projects or automobile accidents. Sometimes for projects that take longer, more permanent and heavier indicators are put in place if the diversion is to last for a long period of time.
Therefore, cones are used for a very temporary use as they are easily moved and not as sturdy as more permanent things. They serve many diverse purposes today and have come a long way from their start long ago.
They were invented in 1914 by Charles P. Rudebaker. Although they were originally made of concrete, they are typically made from brightly colored thermoplastic or rubber today.
Recycled PVCs from bottles can be used to create these modern safety aids. Not all traffic cones are even in a conical shape.
Ones with a pillar shape have a similar function but are more like movable bollards. There are many things used to day, even electronic signs, to manage traffic.
The most common use for these devices is for outdoor direction and management of passengers during road work or other various situations requiring redirection or advance warning of hazards, dangers, preventions or unusual situations in the flow of passengers.
They are sometimes used to indicate where children are playing or to block off entrances of different kinds. Sometimes, they have a fitted reflective sleeve that will increase visibility for use in dark places or during the nighttime.
In 1989, the US Federal Highway Administration's Manual on Uniform Traffic Control Devices (MUTCD) was amended to mandate increased night time visibility in addition to the reflective collars. The new requirements enforced the use of white bands on the cones.
So, reflective collars, white stripes created from white reflective plastic are required to be slipped over the funnels tightly. Also, tape or adhesive can be used to attach the collars permanently.
They are now designed to be highly visible and completely mobile. Various sizes are used and commonly range from around 30 cm to barely over 1 m.
Traffic funnels can also come in many different colors including orange, yellow, pink and red as the most common colors as they are all very bright. Some others include green and blue, and may have reflective strips to increase their visibility.
The most common kind is a fluorescent orange which comes in a variety of about five sizes. Cones are easy to move or remove whereas sturdier and larger markers are often needed for long term construction sites.
Such items include barrels with reflective strips which are often weighted with sandbags. Sometimes Jersey Barrier is preferred in cases where land closures must be physically blocked against careless cars.
In many countries such as Australia or American states such as California, traffic barrels are rarely seen. They use, instead, bollards which are larger and sturdier warning or delineation devices.
They are typically 1150 mm high fluorescent orange posts with reflective sleeves and heavy rubber bases. In Canada, they are often referred to as pylons, but they use barrier boards which are larger and need to be blocking larger areas for longer periods of time.
There are many purposes for them beyond traffic management indoor and outdoor. For example, they are frequently used in indoor public spaces to designate areas which are closed to public pedestrians.
In many cases, restrooms are out or order and need to be blocked. In other instances, dangerous conditions such as a slippery floor may be present.
They are also used on school playgrounds to limit areas of a playing field. Typically the miniature forms will be used for these purposes or even some disposable full size ones made of biodegradable paper.
The uses of cones are endless, and they have proven to be a reliable resource. They are simple, but they are important for many people.
