Bollards in Europe Are On Another Level..

[@Frankon81]

Apart from protecting pedestrians. Bollards also prevent cars from parking on the sidewalk.

[@RatobornaShparg]

Yeah, I would say that most of bollards here in Europe are for preventing parking on sidewalks, especially those slim ones because they are not that tough and they are basically just screwed down to the pavement, and retractile ones are used mostly for pedestrian areas where you want to allow cars sometimes, like deliveries and such

Older denser cities tend to have those kind of elements a lot more. Some of it is just visual stuff, some have been proven to be necessary, some are built after they have seen it necessary near by... Population density spawns those kind of elements, not always because of pedestrian safety but still having the same effect. Government and financial buildings are often in a high traffic area for a reason, so.. stop thinking about conspiracy or "they don't care about me".. while the latter is true with financial buildings there can easily be a common sense reason: the bollards are not there because of financial building, the financial building is there because of high traffic and where there is high traffic you more commonly see bollards.

Those bollards in chicago are definitely to protect the building. They do not even cover the waiting area for the pedestrian crossings.

We have a lot of those retractable bollards at the entrance to pedestrianised streets in the UK. They can be lowered to allow emergency vehicles access to pedestrianised areas and to allow for deliveries to shops - usually between designated hours. One of the funniest things I have seen was on a very busy day in Wakefield in West Yorkshire. The bollards had been lowered to allow an ambulance to enter and, as it passed, the crowds of pedestrians parted and then came back together again. looking up the street, a homeless man began to rise above the crowd with his arms outstretched in some crazy David Blaine style magic trick. He had stood himself on one of the lowered bollards and stayed there as it rose back in to position. Very cool and funny. At a different time, but on those same bollards, I saw a transit style van try to sneak on to the pedestrian street following an authorised delivery vehicle. It didn't quite make it on time and the whole front end was lifted clean off the ground. Those kerbstone crenelations that you saw on the edge of the Paris sidewalk are actually very effective at preventing motor vehicles mounting the pavement and/or parking on footways and cycle paths. Pedestrians and bikes can pass between them and they are way cheaper to buy and install than metal bollards that you have to bury deep in to the concrete.

[@Pancake_Nix]

After my country joined the EU, we started closing off some city centers for general traffic. And it seems they haven't thought out the system very well, because I saw an ambulance wait at one of those entry points for over 5 minutes! They improved this over the years, but it's still not perfect. Ouch! Poor van! He'll surely think twice now when trying to sneak into the pedestrian zone. The ones I have here won't raise if they detect a car nearby, even if it's a random bloke following an authorized vehicle (before the pedestrian zone there is parking for local tenants, that also has the same descending bollard). But that means that from time to time you will get a confused tourist who's just trying to find a parking spot (it's a struggle in the town center) and getting "trapped" inside. 😅 And that story with the Homeless Blaine is hilarious!

But long before we went down that terrorist road we had an ongoign trend to more/heavier barriers because of drunk drivers taking out groups of people for example at a bus stop and so on. And a lot of our narrow crossroads have the bollards on the corners because of trucks dragging their trailers onto sidewalks on a turn.

Couple of observations: 1. In Britain the retractable ones are often guarding pedestrianised roads, they will lower for emergency vehicles or buses but private vehicles cant access the road (or you might have restricted hours such as them being lowered at night but raised during shopping hours). Its very unusual to have them protecting your garaged car from theft like shown in the video but automated gates sometimes supplemented with bollards would often be protecting the drive ways of mansions. 2. You will 100% see them guarding any place that could be a terrorist ram-raid or car bomb target stopping vehicles getting too close to entrances. 3. In general they will be protecting pedestrians on heavily trafficked side walks or stopping motorists taking a shortcut over the pavement. 4. Those wide retractable ski-slope like ones you see in the video are often used in car parks to stop people trying to drive out an entrance rather than going through an exit barrier arm to avoid paying. Generally places you dont mind people going in one direction but want to prevent them from going in the opposite direction. You also see them at the entrance to high security buildings like Prisons/Government/Police stations/etc.. where they check ID's of people driving in to stop anyone trying to run the check point.

Here in the UK bollards have been around for ages, going back to the days of stagecoaches & horses & wagons, placed to protect buildings & walkways. The ground sunk ones are quite recent, & are mostly used to close of areas to traffic for part of the day, while allowing vehicular access for deliveries etc at certain hours. The retraction allows for emergency vehicles access when required. Bollards are mostly used to prevent parking on pavements, & to close off areas where vehicles are not allowed, but bicycles & pedestrians can pass through. People can & do use bollards at private properties, businesses etc, to prevent vehicular access or theft. There are simple lift up, or folding types, for use as & when required. The London, & other cities, old cannon bollards were originally real cannons, but later the design was continued in fake cannon style. The recent rise in vehicular terrorist attacks has caused Governments to increase the number, & strength, of these & other forms of barrier, particularly in central London, but also in other tourist busy places, airports, train stations etc. Nobody is likely to deliberately run at 80 MPH into a bollard, unless a crazy person or fanatic. Mostly a low speed accidental hit on a bollard would stop with much less damage.

Those smaller bollards are often used to stop people from parking on the sidewalk. But those pop up bollards are mainly used for keeping cars out, while still giving emergency vehicles and sometimes delivery vehicles or taxi's access to an area. Funny story, in my city there's a hospital (I believe Ian reacted to a video of motorcycle police escorting an ambulance to this hospital) and there used to be these pop up bollards on one end of a road leading up to it. So only busses and emergency vehicles could pass through. But they moved these bollards to the other end of that road so you'll have to approach the hospital from the other side... And for months at least one or two cars a week would crash into those new bollards! Even now years later people still sometimes crash into that bollard.

In most European cities, bollards in most cases do not constitute an "armored barricade", but are intended to prevent cars from parking in specific places. For example, in front of pedestrian crossings, where cars would limit visibility. Unfortunately, many drivers ignore prohibition signs and park in places not intended for this purpose, so pedestrians' rights must be protected with such bollards.

There are also cheap versions of posts for use in home protection. You have to manually remove and insert them.

There are also posts made of bent stainless steel pipe in a very light version. They protect your purchased parking space outside multi-family buildings with apartments. It is assigned to the apartment you bought and protects against someone else from outside being able to park on it when it is empty

On my way to the bus we have to cross a busy crossing. There are 3 lanes heading downhill towards the crossing. A van was driving way too fast down the hill towards the crossing. The right lane and left lane were blocked by cars waiting for their opportunity to turn, so only the middle lane was open. The middle lane was slightly blocked by a car that was trying to take a turn from the opposite lane. The van sped through the middle lane, turned slightly right to avoid crashing into the turning car, slid out and crashed straight into the bollards on the opposite side with a lot of people behind them waiting for the traffic lights. When I came back from work later, I saw the aftermath: One Bollard was completely gone and a second was bend 45 degrees, but they stopped a speeding van.

Here in Germany at least sometimes there are, not exactly bollards, but like a wider barrier in front of pumps. But most times you will only see some sort of either elevated curb, or more like some kind of deflector that would push tires away from the pump. Easy to trip over those.

[@kalasanty433]

@@alexanderkupke920 I see mostly high metal curbs here in Poland

[@alexanderkupke920]

@@kalasanty433 what you see here is really different from gas station to gas station. some even include those curbs or rails into their design, like Aral where they put a thick diameter blue coated steel tube around the pumps (I think sometimes even with some integrated lighting). In other places I have seen like a steel tube frame, more like what you would otherwise find to chain a bike to. Most often just some elevated pedestals with a high curb the pump sits on, just to prevent someone from accidentially hitting the pump when not paying close attention and trying to get past the car at the pump next to it. And that is really all they protect from, someone getting to close or turning into a pump. at some speed i have seen it happen that cars crashed into the pump, despite a high curb. (I think last time close to where I live an elderly person mixed up throttle and brake and went straight into the LPG pump, which even had kind of an additional guard rail on top of the curb.) But for this I guess, actually legislation may differ across countries on how much protection is needed for those pumps.

Where I live in the uk, there are lots of pedestrianised streets/areas and they will generally have a line of bollards blocking the entrance to those streets. But when people need to get deliveries in for their business, they have like a code that can put in and the bollards retract to let the van/lorry/truck in. They also have the retractable ones in car parks sometimes in place of the normal swing barrier things

[@rikardottosson1272]

In the UK you can’t do anything if someone parks in your driveway. It’s a civil matter so you can’t just have a car towed. Hence why some people get small removable bollards on their driveway to prevent people from parking there without permission, especially if they live next to a school - people make crazy decisions when late for school drop off and schools never have drop off lanes or off street parking.

[@zoolkhan]

think less anti-terror bollards, and more anti-parking bollards. So in europe you see the spots equipped with bollards, where fals parking notoriously would occur. Delivery trucks and other types of inconsiderade cunts. The automatic bollards are used to allow for first responders and legitimate (shop owners in pedestrian zones) traffic through. In only a very few occations (since 9/11) it has to do with protecting someone from weaponized vehicles.

[@carpediem4091]

Nice - the city - attack made it a whole lot about anti-terrorist. Also look at the christmas markets. Beforehand there weren't any bollars installed specially for it. Nowadays they're as much a part of things as all the decor. Truth is that it started as protection from traffic and in the last couple of decades they've been popping up a lot due to the terrorists. It is what it is. Lets stop pretending we aren't changing our ways due to those bc we all are.

[@rtw777]

Generally, smaller bollards are anti-parking on road sides. Big ones are anti-terrorism (or accident) around larger sites, or fuel pumps etc. They can also appear as flower beds, heavy duty benches etc. Raisable bollards are for traffic control or anti-terror at gates. Small bollards on properties are often foldable and lockable to allow only the owner to park.

[@Anson_AKB]

there are different purposes for bollards, and thus also different sizes and strength ... several decades ago, we had few or even none here (in germany), but when more and more cars parked illegally on sidewalks, they started putting them up. but that kind only needs to be strong enough to damage cars and drivers will stop even trying :-) and then with global developments all over the world, there are the more massive ones for important locations, where real protection is needed, including eg some mobile ones that they put up years ago when someone had stolen a truck and drove into a christmas market. those look to pedestrians only like a bit elevated cable protection at construction sites, but can stop trucks similar to the shown "mobile truck stopper" in the video.

[@Yvolve]

Bollards are most common in major cities, smaller towns don't use them as much as there is less traffic. They're especially common in cities that became very car centric, as protection was needed. The Netherlands doesn't use them that much, as there are a lot of bike lines, creating distance between the car lane and sidewalk. There are other measures used to slow down traffic where needed, to keep the roads safe. On narrow roads, the cycle lane is part of the car lane, so cars go slower to not hit a cyclist (remember, every Dutch driver grew up cycling, there is respect). When the cycle lane is separate, there are speed bumps and/or a tall curb between the car and cycle lane. Neighbourhoods often have brick roads, which make a lot more noise, so people slow down instinctively. Th roads are just wide enough for two cars to cross, which slows people down as they don't want a crash. Pedestrians and cyclists also hear cars coming from further away. Pedestrian crossings without a zebra get an "island" in between the two lanes, making it easier to cross without traffic lights and the car has to turn to avoid the island. This slows the car down and forces the driver to pay attention. Zebra crossings are often on a big speed bump. forcing the car to slow down. Some have a sign with flashing LEDs that are activated by a sensor. If someone wants to cross, it flashes. At night, the zebra crossing is lit as well in some cases, especially on roads where people drive fast, have heavy traffic or have many side roads. NotJustBikes has some great videos comparing American and Canadian roads to Dutch ones, as well as some other European countries. The ones on "stroads" will probably make you think most about the American road network, and why walking and cycling isn't common in the US.

Used to work in a corner shop, next to a street that got closed off to car traffic. It was still open for buses and police etc. They placed a bollard that would retreat into the ground when a bus or police/fire/ambo came close enough. Sometimes, people thought they could make it if they follow the bus closely enough. Nobody ever made it. The bollard would come up just as the car would start to go over it and ram the engine. The bollard was actually removed for a while because it kept destroying engines to such a degree that the engine fluids leaking into the ground were becoming too expensive to sanitate... Long story short: I've seen dozens of cars standing almost upright on their rear wheels with the fronts pushed up by a bollard.

When terror attacks were happening around Europe 12-15 years ago and trucks were popular weapons-of-choice and cities were building big concrete barriers, Prague was congratulated by EU higher-ups for having an effective anti-terrorist measure. All of the bollards and railings placed around the streets, town-squares and infront of airport to limit parking and car-access to pedestrian-only zones and limit pedestrians from crossing a road. It was just so funny it was found to be such a genius idea. The Office congratulations meme template fits here.

[@chassetterfield9559]

When I worked in Cambridge, there were automated rising bollards to keep cars out of the City Centre between 10:00 -18:00. Emergency services, buses & taxis could gain access during that time. They had a radio 'tag' on the front & rear bumper, which triggered the bollard to drop, allowing access. Of course, some 'clever' people thought that they could tail-gate a permitted vehicle through the barrier. One day I was sitting in the pub, waiting for the bus, to go home. Someone tried tailgating a taxi through the barrier, but it rises VERY quickly. It didn't lift the car up, it rose through the gearbox & engine [ FWD ]. When they came to clear the wreckage, they pressed the button to lower the bollard again, which happened, but the car could not even be pushed out of the way. The transmission was pulped, and totally locked up. I'd bet they didn't try that again.

In Europe - there are many different types of bollards - they serve different uses. First use - it is: Cars don't even think about parking (even stopping) here. Or Driving into this street / walkway. On that spot - that area. Second: Closing down some streets for cars passing through. Just stay on the destinated roads - no short cuts through residental streets. Third: You saw that bollard(s) going up and down. Mostly used to block pedestrial zones - mostly in city centers - but letting public transport (mostly busses) pass. Bus coming - bollard goes down - bus passes - bollard goes up. Cars aren't allowed to pass. Or blocking of an area like the location of the Munich Oktoberfest - but letting emergency vehicles entering that area at any time (if they have the "remote"). And being open at night for supplies - by truck. Fourth: The bollards are used to block cars, trucks and else to drive into a building. And - especially in Europe - you can even say in which country you are by looking at the type of bollards. Those "cannon-like" bollards are typical of the U.K.

If I am not mistaken those @12:00 are used to prevent unauthorized access to restricted buildings like embassy, military buildings, etc. Usually only the yellow part is visible and they retract underground (toward the vehicle) to allow passage. They are very rare because, usually, you do not have a path/street long enough toward the entrance of those buildings to get enough momentum to get pass bollards or the other yellow slice, so those are usually used instead.

They also prevent shoplifting, many of these thefts occur with a car that, reversing, breaks the shop window and literally enters it.

As others have mentioned, many bollards are just to stop cars from entering/parking, but not necessarily to stop something in it's tracks like the more heavy duty ones. There's even bollards which are just a flexible plastic, meant to be ran over by emergency vehicles, so they just need to drive over them slowly, and they spring back up when the vehicle has passed. Those are basically like a sign, but a bit more effective since you're clearly driving somewhere you shouldn't be. And the emergency vehicles don't need to stop, pull them out/lower them and put them back, losing less time.

The premise was, when traffic freezes up in winter (it's always bad here, the traffic, not the winter) - bollards would prevent driving on the sidewalk (and make congestion even worse). And the city chose the least conspicuous, very low bollard model so that snowplow tractors will safely clear it. Two meter underground, only 30 centimeters above it. Almost invisible in snow, and almost each winter night drivers hit them, smashing their oil pans and spitting hot oil all over.

Since you checked Paris : We tend to have smallish bollards in paris itself because the speeds are fairly slow in most of the city. Those smallers bollards are less sturdy than the ones shown in the tests; They will stop a vehicle, but will bend when doing so. They need to be replaced afterward, but since incidents like that are fairly rares and those bollard are a lot cheaper, it's not much of an issue. However, in the last 10 years, new polymer, flexible bollards are cropping up; they are small and bend which make them unable to stop vehicle. Those serve a role similar to a permanent traffic cone : they delimitate spaces, and shouldn't be run over, but let emergency vehicles through without issue. The white "curbs" on the sidewalk are just there to make parking on the sidewalks impossible.
