Construction[edit]

I am German and I wonder whether this is also a bollard or has it a specific name because it´s out of stone ? de:Bild:Poller.jpg --84.166.221.199 15:20, 1 February 2006 (UTC)[reply]

A bollard may be made out of stone, but they usually don't have any chain attached; they're typically free-standing. Matt Gies 16:03, 1 February 2006 (UTC)[reply]

Kindly also include the mechanism of operation of modern day bollards (Protective Rising Bollards) available in the market. It is mentioned that the price of Bollards ranges from $11000-$100,000 and the most expensive bollards can stop vehicles at 50 mph. But what will be the weight of vehicle travelling at 50 mph can be stopped. Also whether this stopping capacity relates to a single bollard or two or three bollards erected together. Also does it mean than a bollard costing $100,000 can only stop a vehicle travelling at 50 mph. Please clarify. Virjin Jawahar - Bangalore, India

Proposed Merger[edit]

I suggest that the T-Top Bollards article be merged into the "Road Traffic Control" section, which already mentions the use of these bollards, in context. The "T-Top..." article is little more than a catalog entry from a hardware store.  Gordon | Talk, 14:19, 31 December 2006 (UTC)[reply]

OK, one "aye", no "noes", carried. Done.  Gordon | Talk, 13:16, 9 January 2007 (UTC)[reply]

Eighteenth century bollards?[edit]

This article implies that bollards as a means of traffic control are a recent invention. In the background of this image, however, you can find five bollards protecting the ancient arch from renaissance era vehicles that might come careening down the hill. I suppose it's possible that the pillars are merely decorative, but according to Arch of Septimius Severus: "The damage wrought by wheeled medieval and early modern traffic can still be seen on the column bases". Should the above image be included in the article? How much is known about the 'history of bollards'? James Kell 21:06, 2 February 2007 (UTC)[reply]

FYI, the image has been moved to Wikimedia. T71024 (talk) 08:55, 2 January 2013 (UTC)[reply]
OK, I've added a short history section and used this image. I've also done some rearrangement and editing of the article as a whole, though a lot more could be done. GrindtXX (talk) 21:50, 3 January 2013 (UTC)[reply]

Decorative Bollard[edit]

Decorative bollards are placed in Geelong, Victoria, Australia, to enhance the landscape as a form of outdoor public sculpture. Usually they are made of timber, minimally modified from the traditionally cylindrical, wooden, maritime bollard shape, but brightly painted to resemble human figures. Such figures - which may be historical or contemporary, particular or generic - are sited singly or in clusters along the waterfront and in other areas where people gather. Decorative bollards have become a well-known feature of the city of Geelong and reflect its history as a major Australian port.

I don't think that a type of Bollard in one city is really notable. —mako 20:05, 22 October 2007 (UTC)[reply]

Vocabulary question[edit]

(Also asked at Talk:Mooring (watercraft), but I haven't gotten an answer there): What is the name for the structure that the hawser is wrapped around on the ship, analogous to a bollard? I realize that it can be a capstan, but what if it has no setup for mechanical rotation? - Jmabel | Talk 16:36, 29 April 2008 (UTC)[reply]

Bitts— it's one of those peculiar words like "pants" and "scissors" that is plural only. The definition at http://en.wiktionary.org/wiki/bitts is a bit dated. HausTalk 00:03, 11 May 2008 (UTC)[reply]

What Is This Bollard-Like Object?[edit]

What is this thing called? It is used a lot on the streets in my neighborhood (Santa Barbara, California). It is not a cone and it is not a bollard. I suspect it has a name of its own, but I don't know what it is. If someone does know, I think it would be appropriate to make mention of it as a "See Also" topic in the Bollard article, just as Traffic cone is.

I'm pretty sure it's just a bollard.24.190.34.219 (talk) 04:19, 7 August 2009 (UTC)[reply]

If Bollard is chiefly a British term, what's the term primarily used in the U.S.[edit]

The article notes that the word "Bollard" is chiefly British, so what's the American English equivalent? They've been around forever, and if we haven't been using bollard then there must be another word. 24.190.34.219 (talk) 02:56, 22 September 2009 (UTC)[reply]

Depending on the situation, I've heard, "pylon," and, "stanchion," used for some of the things pictured on the page. 208.75.77.65 (talk) 22:09, 25 June 2010 (UTC)[reply]

Ad?[edit]

Split into traffic bollards and dock bollards?[edit]

I notice that there are two different item types with different functionality: the bollards on docks for tying up ships, and the bollards on streets for restricting traffic. They simply share the same name in English. Would it be worth splitting them into separate articles? This would also sync better with other language wikis where there are different words for the two concepts. Horatio (talk) 23:40, 8 June 2013 (UTC)[reply]

An ancient suggestion but I think a good one. They seem to me to be two distinct concepts that are only linked by a shared name. Without the shared name there’d be no argument that they should be different articles. Just my take and I recognise the authors must be happy with things as they are.2A02:C7F:5E8D:9C00:2C75:1B18:4F37:6328 (talk) 16:12, 8 February 2020 (UTC)[reply]

@GrindtXX[edit]

OK then. I shall. I'll try to use only proportionate and necessary pedantry. Most people think that the name of the famous deserted ship was Marie Celeste (Source: O.E.D. and The University of Life). Wikipedia was until recently riddled with this misapprehension. I've corrected about 35 instances, and now almost all is light and truth. A disambiguation page for "Mary Celeste" is on its way, as is one for "Marie Celeste", and there'll be an article on how the two became confused thanks to Arthur Conan Doyle. The reason for a zero-tolerance approach is that the more unchallenged examples there are on Wikipedia of what I shall call the alternative form of the ship's name, the longer the misapprehension will persist. Wikipedia has the opportunity, and, some might say, the duty to disabuse the ill-informed in this matter.

Btw, something I've noticed about Wikipedia is that it's a favourite tactic of the outraged "editor" to advise those with whom he or she disagrees to read something or other, often the rules of Wikipedia itself, the implication being that the other's actions are due entirely to ignorance (where ignorance is not a failing but a sin). I also note that it is always the other person who is insisting.

I'm surprised that a PhD, especially one who likes to advertise his or her qualification, would wish to assist in the perpetuation of a misunderstanding, particularly since the corrective observation does the Doctor no harm whatsoever.

It's good to talk, and I hope the above helps to explain the reasoning. If an aversion to pedantry of any degree on Wikipedia is to be combated, then anyone undertaking the task will be very busy indeed.

I realise, of course, that a change of opinion is and always was completely out of the question, but I've followed your suggestion. I know little of the rules and regs of Wikipedia and have no desire to learn them. The disciplines required to attain a PhD must be invaluable when turning them to one's advantage while snorting with indignation at an article about bollards.

So let's leave it as it is for a while, and let us wonder if anyone who chances across the passage will think, "See, I knew that's how you spell it." We shall never know.

Extended content

Etymology[edit]

Previously, simpler terms such as "post" appear to have been used. The Norman-French name boulard (still often found in Normandy) and Dutch bolder may be related.

History[edit]

From the 17th and 18th centuries, old cannon were often used as bollards on quaysides to help moor ships alongside. The cannon would be buried in the ground muzzle-first to approximately half or two-thirds of their length, leaving the breech (rear end) projecting above ground for attaching ropes. Such cannon can still occasionally be found. Bollards from the 19th century were purpose-made, but often inherited a very similar "cannon" shape.

Similar posts can be seen in many historic paintings and engravings.

In the Netherlands, the Amsterdammertjes of Amsterdam were first erected in the 19th century. They became popular symbols of the city, but they are now gradually being removed and replaced with elevated sidewalks.

Types[edit]

Maritime[edit]

Mooring bollards are seldom exactly cylindrical, but typically have a larger diameter near the top to discourage mooring warps (docklines) from coming loose. Single bollards sometimes include a cross rod to allow the mooring lines to be bent into a figure eight. Small mushroom-bollards are found on lock approaches for advancing boats waiting for lock access.[citation needed]

A conventional measure of the pulling or towing power of a watercraft is known as bollard pull, and is defined as the measured force exerted by a vessel under full power on a shore-mounted bollard through a tow-line.[citation needed]

Roadside bollards[edit]

Tall (1.15 meter/4 foot) slim (10 cm/4 inch) fluorescent red or orange plastic bollards with reflective tape and removable heavy rubber bases are frequently used in road traffic control where traffic cones would be inappropriate due to their width and ease of movement. Also referred to as "delineators", the bases are usually made from recycled rubber, and can be easily glued to the road surface to resist movement following minor impacts from passing traffic. The term "T-top bollards" refers to the T-bar moulded into the top for tying tape. Bollards are regarded as an economical and safe delineation system for motorways and busy arterial roads; and, in conjunction with plastic tape, for pedestrian control.

Traffic bollards used in the US are very similar to devices found throughout the UK, except that US traffic bollard shells display the MUTCD (Manual of Uniform Traffic Control Devices) "Keep Right" symbol (R4-7). In addition, the traffic bollard also has a yellow diamond below the "Keep Right" symbol instead of a yellow shield.

Traffic-island bollards[edit]

...and at the ends of pedestrian refuge islands, typically located at mid-block pedestrian crosswalks.

...(fog, rain, snow, haze, etc.) and to indicate that braking may be required. Illuminated bollards are also used in Hong Kong, a former British colony.

Bell[edit]

A variant on the bell bollard is the "Martello bollard", its sloped shape inspired by the profile of historic Martello towers.

Removable[edit]

Bollards may be hinged at ground level, allowing them to be folded flat to permit vehicles to drive over them. In such cases they are generally fitted with padlocks at the base, to prevent their being lowered without proper authorization.

Rising bollards can be retracted into the roadway to allow traffic to pass, or deployed to stop it.

Removable bollards may be fitted into a permanent metal ground socket, from which they can be removed entirely to allow traffic to pass. A polypropylene ground socket is also available that protects the paving and foundations from damage when the bollard is struck. This design uses a self-locking taper to enable bollards to be easily removed and relocated.

Retractable[edit]

Retractable or "rising" bollards can be lowered entirely below the road surface (generally using an electric or hydraulic mechanism) to enable traffic to pass, or raised to block traffic. Rising bollards are used to secure sensitive areas from attack, to enforce time-limited traffic regulations, or to allow access only to particular classes of traffic.

Racing[edit]

Some forms of motorsport use removable, high-visibility bollards on road courses and street courses to mark the apex of certain corners. They are used to deter cutting a corner too tightly and violating track limits: in most racing series, drivers may incur a penalty for colliding with or driving inside these bollards.[citation needed]

Racing bollards are very lightweight and built to break off at the base when hit so as to not damage the vehicle; this feature of bollards makes them favored over "sausage kerbs"—also used to prevent cutting corners—which are elevated rigid structures that run along the inside of a turn. In contrast to bollards, sausage kerbs are much more unforgiving, and vehicles that hit them can be severely damaged or launched airborne upon contact.[citation needed]

Covers[edit]

A more recent development in bollard technology are bollard covers. They are used by many industries and communities as a cost-effective way to increase safety and refresh old and worn-out-looking bollards without having to completely replace the original bollard. They slip over the existing bollard and can come in a variety of shapes and styles. Because they are easily removable, they can be replaced quickly, and depending on their material they may never need painting and are resistant to scratching and other wear and tear. Traffic bollard covers are typically made of tough recycled plastic and have high-visibility colours to ensure motorists see them. Decorative bollards are used in street areas to enhance display and may come with LED lights to increase visibility and safety at night.[citation needed]

Protective[edit]

They usually consist of a simple steel post either anchored to concrete, cored into a hard surface, buried in the ground or secured on a self-locking taper or impact recovery system to protect the surrounding foundations when a bollard is struck.[citation needed]

They are often used by retailers to prevent "ram-raiding" burglaries. Large concrete blocks or structures are used with the same purpose but have an important aesthetic and visual impact. Large concrete planters are a decorative alternative.[citation needed]

Rising bollards are increasingly common around the world to hinder vehicle-based terrorist actions from achieving close proximity to buildings, and are also used to prevent terrorist vehicle-ramming attacks such as the 2007 Glasgow International Airport attack. They are also useful in mixed-use public spaces, which support both pedestrian use and emergency or service vehicle use. These bollards are usually priced between $11,000 to $100,000 depending on their ability to resist ramming vehicles, based on speed and size of the vehicle. The most expensive bollards can stop vehicles at speeds of about 50 mph (80 km/h).[citation needed]

Such bollards are used for hostile vehicle mitigation and are designed to protect against potential vehicle borne improvised explosive devices (VBIED) and vehicle as a weapon (VAW) attacks such as those seen in the Nice attack in 2016 and the Westminster Bridge attack in 2017.[citation needed]

Dragon's teeth[edit]

Large concrete structures called dragon's teeth were invented during World War II to slow down, stop or channel enemy tanks.[citation needed]

Lights[edit]

Lighting bollard in St David's, Pembrokeshire

Bollard lights are a type of architectural outdoor lighting fixture comprising short, upright ground-mounted units, typically giving off light from the top or the sides, and used to illuminate walkways, steps or pathways.[citation needed]

Solar bollards store energy during daylight hours in order to illuminate during night. They use either a photocell or algorithms that determine whether the solar cells are receiving light to determine when to illuminate.[citation needed]

Other applications[edit]

The following list of open areas is encompassed by the ABA, NCEF and WBDG recommendations: [citation needed]

Architectural design functions[edit]

Bollards serving dual aspects; they prevent cars from trespassing and also aesthetically complement the surrounds of the Church of St Matthew in Qrendi, Malta.

Listed below are the building design objectives and requirements under fire or security related instances on campuses and their relationship to the use of bollards according to the Association of Higher Education Facilities.<ref>Charles G. Oakes, [https://eric.ed.gov/?id=EJ910313 Whole Building Design Objectives for Campus Safety and Security: A Systems Dynamics Approach], ''Facilities Manager'', July/August, 2010, pp 21-26</ref>

  • Accessible: Fire lane bollards will accommodate persons using wheelchairs.
  • Aesthetics: The fire lane and its bollard style complements surrounding landscape design.
  • Cost-effective: fire lane system life cycle costing.
  • Functional/Operational: Building architect determines if entrances to building envelope can accommodate first responders or whether entrances require retrofitting, and authority having jurisdiction and first responders determine if the fire lane can readily be accessed through the bollards under emergency conditions.
  • Historic preservation: City planner address the special needs in historic districts and of historic buildings to accommodate fire lanes and bollards.
  • Productive: The HR officer comments on felt security of those working in the protected building, and all first responders pass on their ability to perform under fire mitigation conditions.
  • Secure/safe: Input by building safety or security officer and representative first responders to assure hallways and stairwells can accommodate first responders and that the fire lane is free of all obstructions 24/7.
  • Sustainable: Landscape architect and surveyor comment on long term sustainability of area impacted by fire lane and use by first responders.

Artwork[edit]

Many other towns, such as Winchester, England and Pristina, Kosovo, have painted ordinary bollards in unusual decorative patterns.[citation needed]
